- Net Framework >> Looking for a book on writing ASP.NET Controls with VB.NETI am an ASP.NET developer who would like to start learning about writing
ASP.NET custom controls using VB.NET. I already have a reasonable amount of
knowledge with making ASP.NET pages, and am looking for a book specifically
on writing controls. Here are some things I would like the book to talk
about and my preferences as to how I would like it to be shown/explained:
1. I want it to use VB.NET for the examples, since that is what I write all
my sites using and have experience with.
2. I would prefer that the book use many examples, because I feel I learn
better when I see examples.
3. I want to know how to make the different properties be either displayed
or not displayed in the Visual Studio .NET Properties Palette, as well as
other things that affect the appearance in Visual Studio .NET.
4. I want it to concentrate only on ASP.NET Custom Controls.
Thank you in advance to anyone that can help me find a book on this topic.

- Visual C#.Net >> adding icons to controlsHi!
I have made a few custom controls. E.g. I have a ColorTextBox which inherits
the TextBox class...
When I build the project and add it to the toolbar (through Add/Remove
Items) the control has
the default icon next to it...
Is there a way I can change the icon displayed in the toolbar? Through some
attribute perhaps?
Thanks...

- ADO >> ADO.NET 2.0 - Simple question for you...I have an ASP.NET 2.0 website. I want to write a function in ADO.NET 2.0
(VB.NET) that does the following:
1. Opens up a connection to my SqlExpress db. (The connectionstring is in
the <connectionStrings> section of my web.config)
2. Runs a query, storing results in a datatable.
3. Closes connection
Can anyone assist?
Thanks!

- Dotnet >> ASP.NET Integrated AuthenticationI'm developing a web application for our local intranet that will allow users
to pull up a webpage and update or deleted or insert records into a database
as well as run reports etc...
Our DB server is on a Win2k3 OS using SQL Server 2000
Our Web server is on a separate Win2kr OS using IIS 6
Both the servers and the clients are part of the same domain.
We've turned anonymous access off on the web and are passing the integrated
authentication from the client's machine (through their domain login). The
user has been granted all the correct permission to the database server and
the database that will be updated. However it seems like the authentication
is being passed to the web server and then the web server is passing a
different set of authentication on to the database server? The
authentication it is passing on to the database server is DOMAIN\MACHINENAME$.
If we add that machine name to the SQL Server as having permission to do the
update/delete/select we can get the app to work just fine. However, what we
want to do is to pass the clients authentication on to the database server...
not the web serverâ??s authentication.
Any help I could get would be much appreciated..... this is driving me nuts
and seems like a pretty common practice (having the db and the web on two
separate machines).
Thanks in advance.

- ADO >> Crystal Report - Page break after Report header !Hi all,
I'm actually encountering the following problem. I've got a report
with standard report header, page header and detail sections. But on
viewing mode, CR generates everytime a page break right after the
report header section, so the data start to be displayed only on the
second page. When all data could fit on only one page, it worked good.
The problem came when i added more fields, to report, needing 3 pages
at least. I don't know why, CR does this, where is it told to generate
this page break, cause the options "New page after, before" are not
checked.
Any help apreciated,
Thanks,
Mike.

- Net Framework >> Profiling/Debugging Real Time Security ChecksI have a medium sized application (say 50k lines) that occasionally will
spike the % of time in RT security checks performance counter between 50 and
95%.
It can perform hundreds of thousands of code access security permission
checks in a few seconds in some cases.
I know that I can set a permission set on a higher level method and demand
then assert to help allieviate some of these checks, but how do I go about
determining what method to assert the permissions and which permissions to
assert?
I guess what I'd really like is to get a list of methods with the number of
calls and the number of code access security permission checks performed
(inclusive and exclusive).
Any ideas of how I can go about profiling/debugging this issue?

Installed Framework 2.0 on this box, and it says that it installed, but
the tab for ASP.NET on the properties doesn't show up. We've removed &

Does anyone have any ideas as to what's happening to this?

- Dotnet >> .NET control event with java script handlerHi all,
I have created a .NET Windows control with c#.
I have placed the control on a HTML page within the OBJECT element.
Everything works fine up to now.
Now, I wanna implement the following stuff that the control must support.
The control must provide a method called InvokeJavaScriptFunction
The prototype of this method is:
InvokeJavaScriptFunction(<point to java script function>)
where <point to java script function> is a pointer to an existing java
script function in the HTML page.
The InvokeJavaScriptFunction method of the control is invoked within the
HTML page when the page is loading
<head>
<script language="javascript">
function MyJScriptFunction()
{
....
}
</script>
<OBJECT id="MyControl" .....>
</OBJECT>
</head>
<body onLoad="MyControl.InvokeJavaScriptFunction(MyJScriptFunction)">
.....
</body>
Inside the control.... the InvokeJavaScriptFunction is performing some stuff
and after that it should invoke the java script function on the page.
In other words, the InvokeJavaScriptFunction takes some actions and then it
must turn back the control on the page invoking the script function.
You can think at this like to an event.. the InvokeJavaScriptFunction is
doing its job and then fires an event on the page, where the handler of the
event is the provided java script function.
Do you have any idea how to implement this must have functionality of my
control?
Thanks,

- ADO >> Use OleDB DB2 provider type without extra software?I recently realized that I need IBM's iSeries Access installed to use
Provider=IBMDA400.DataSource.1 in an OleDB connection string.
Is there any .NET 2.0 class or dll that provides DB2 data access

alternatively, can I pack whichever specific class/dll provides
IBMDA400.DataSource.1 into the project itself (and not as a reference

- Microsoft Project >> Changing resource units and levellingI want to change the resource units assigned on the
resource sheet i.e. reduce from 100% to 50%.
Then reflect this change in the tasks on the plan. Tasks
are set to fixed unit and I'd expect the maximum
allocation for the resource to change to 50% and the
duration of the task to extend.
Currently the duration stays the same and levelling
returns errors.
Is there a quick way to update tasks to reflect the

- Dotnet >> Subclassing the PropertyGridFolks -
I've done some searching on the 'net, and I think I know the answer to my
question, but I wanted to pose it anyway, just in case.
I'm embarking on a new project, and we're investigating the use of the
PropertyGrid. I've used it in a couple of places before, but never in an
application that goes out to my general user base. We really like the
functionality and capabilities it provides, but some of the display choices
are not exactly what we want.
Some initial tests of creating an inherited control (and my above-mentioned
searching) seemed to show that I'm SOL if I want to override the drawing of
the control elements. I really do not want to go through the effort of
re-creating the majority of this control just so we can draw a couple of
things differently.
Any ideas?
TIA

- Dotnet >> XML->Dataset->DatabaseI am developing a type of data warehouse. Basically, we have 20 client survey
machines that are each separated from the server by space and lack of
network. Yet both need to speak to each other such that the clients know the
latest configuration information and the server contains completed survey
data from the clients. Currently I'm accomplishing this by using a few
special database tables to control the flow of information, and using XML
serialized datasets on both ends and a USB drive to move them back and forth.
The design seems to work.
However, some of these tables have 50+ columns and creating manual insert
statements has gotten absurd. For example, on the server I generate a dataset
based on what needs to be sent to the client, it works fine. I then read in
that XML into a dataset on the client. So now, how do I best get that data
into the SQL database on the client side? The only way I've found to do it is
to create a DataAdapter and insert each row at a time, after setting up all
the commands, parameters, and filling out each row. This is absurd, it winds
up being hundreds of lines. I really want something like this:
Dataset ds;
ds.connection = my connection;
ds.update();
After all, the schema is exactly the same on both ends! So, I don't really
expect the above, but there has to be an easier way than reinventing the
wheel. Basically, I have a dataset full of data that matches the database I
want to get it inside, only it wasn't taken from that database so it's not
just a simple sqladapter.update() call.
Any ideas? Thanks in advance.

- Winforms >> Delegates & EventsI need some clarrification.
I have a class called ChatManager that will manage the interaction between
the ClientUI (WinForm) and the chat server.
The ChatManager will have a number of public events.
When the ClientUI is instantiated it will subscribe to these events
providing its own methods to be used as event handlers.
In the ChatManager code when I raise a particular event...which in turn
calls the delegate...
Will the delegate execute on the same thread as the ClientUI (which it must
do to update the WinForm) or does it execute on some other thread?

- ADO >> Dataset code...is this correct?ok, I am trying to make one call to the db and create a datalist and then
populate a datalist and a datagrid with different filtered versions of the
dataset. I presume this is a better way of doing it than making two seperate
calls to the db where I could just use 2 stored procs to filter the data.
Any help or advice if I'm doing it the wrong way would be appreciated.

- Visual C#.Net >> Call Static Methods from Another ApplicationJust wondering what it would take to call a static method in a static class
of an ASP.NET 1.1 Web app from a different application.
Specifically, I have a little "utility application" (C# Windows desktop
application) that I have on my Web server. All of the ASP.NET Web
applications on the same server each have a static class with static
methods. I'd like to be able to execute the static methods in the ASP.NET
Web apps FROM the "utility application" if possible. Do I need remoting to
do this, or is there another, perhaps simpler, way?
Thanks!

- Visual C#.Net >> C# vs Java SerializationHello,
I have two Java applications that exchange serialized
objects. Although I would like to ultimately convert both
to C# it's a pretty monumental task, especially for
someone just learning both langauges. I thought it might
be more reasonable to start with simply converting the
simpler one of the two and getting it to work. I have
used Microsoft's free Java to C# converter to convert most
of the code, but of course I must complete some of the
conversions manually. I have this basic concern,
however: Will the serialization done in C# be the same as
that done in Java? Also, do all Java compilers serialize
the same way for the same source code? How do I determine
exactly what the serialized data looks like, both
theoretically and emperically? I'd like to be able to
view it at the byte level just for general debugging
purposes. (Of course I could use a packet sniffer, but
that's a little too gross even for a hardware person like
me!)
Thanks,

- Winforms >> Why events are behaving differently for controls in 1.0 and 1.1 of .NET?Hi all,
I have observed that some of the controls in 1.0 .NET framework behave
differently in 1.1 .NET framework.
For example - the ComboBox control:
The combo box is in DropDown mode. Consider the behavior of KeyPress event.
In 1.0 framework, the combobox Text property contains the modified value
during KeyPress event handling.
For eample, if the text in the combobox is "test" initially and I modified
it to "test1" then in key press event the Text property is "test1".
But this is not the case in 1.1 framework. The Text property is old value
i,e., in this case "test" but not "test1".
private void testComboBox_KeyPress(object sender,
System.Windows.Forms.KeyPressEventArgs e)
{
System.Diagnostics.Debug.WriteLine("Text Value in KeyPress :" +
testComboBox.Text);
}
run this in both 1.0 and 1.1 framework.
Due to this my applications are not working properly when I port them from
1.0 to 1.1 .NET framework.
My main concern is: Is this behavior is a bug or intentionally done ?
Because this is causing problems: Help!!!!
Thanks,
Anil.

- Visual C#.Net >> To really understand the Page_Load eventDear colleagues,
I kindly ask the C# developers community to help me to REALLY understand
the Page_Load event, so to REALLY have it under control.
Reason for this question is that I cannot anymore accept passively the
behavior of the â??Web Form Designerâ?? automatically generated code because of
the fact that, in some circumstances (that I can reproduce at will), my code
is victim of a Page_Load multiple â??firingâ??. In other words the Page_Load
event handler inexplicably enters more than once and, at the second entry,
Login credentials are asked again interactively. With disruptive effects for
my current project.
Let me begin this discussion with what I certainly do not know, or I do not
know for sure.
P1) I do not know what really triggers the OnInit event, beyond the fact
that it is overridden in the â??Web Form Designerâ?? automatically generated code
(see hereafter).
P2) I do not know what really the original base.OnInit(e) at last will do.
Indeed Iâ??ve found documentation only about Control.OnInit, but Iâ??m not
convinced it can apply to this case, where no server control in involved
(please see next point), and such an article, as the â??ASP.NET Server Control
Event Modelâ??, doesnâ??t exactly apply. Does it?
P3) Consider that, by definition, â??events associated with server controls
are raised on the client but handled on the Web server by the ASP.NET page
frameworkâ??. Here the case of OnInit, of an .aspx Web page, is rather
different, isnâ??t it? Indeed the OnInit event happens BEFORE the presence of
the Web page on the client computer, indeed this is the very event of posting
a page from the server to the client. And this event shouldnâ??t happen again
until I deliberately ask for another .aspx page. Shouldnâ??t it? But, alas, it
DOES happen, out of my control. And all that is precisely the reason of this
call â??To really understand the Page_Load eventâ??.
As you see Iâ??m really confused (and baffled tooâ?¦).
Thanks for your time.
P.M.
