- Microsoft Project >> Filters: How to filter all the task relationated with one specified taskI'm working with a project that has a planning of more than 900 tasks.
Each 7 days i need to check in detail dome tasks and its incluence in
others relationated with this.
It is possible to customize one filter that permit to see only the
tasks that are in relation with one specified task? Its means that if
I want to see the tasks that are in relation with task "A" (i.e.) I
applied the filter an then i could see the task "B" which is
relationed with task "A", and task C which is relationes with task B,
and task D which is relationed with ttask C, and so on.
This is very urgent for me, because I need to watch the schedule in
details faster.
I was trying for many many time, and i found no solution. Could anyone
help me?

- Visual C#.Net >> Textbox: Select Text On Tabed FocusI thought when you tabbed into a textbox that the text it contained
was automatically highlighted. This use to be the default in win32.
Is there an easy way to do this in .NET. I don't want this to happen
if the mouse is used to select the TextBox.
Seems wierd, If the Textbox has the default text in it the higlight
works but not if you edit it.
Thanks.

- Winforms >> Threading problem with Managed ExtensionsI have a Windows Form developed in C# using the Microsoft
Web Browser control, which is an old-style COM control.
When I run the form from a .NET application that has an
[STAThread] attribute on the startup object, it works
fine. However, when I run the same form from a C++
application using Managed Extensions for C++, I
get "Server Busy" messages when the message loop blocks. I
believe I need to indicate somehow to the Managed
Extensions that I want to run the code in an STA. How do I
do that?

- Net Framework >> FolderBrowserDialog crashes when path is too longHi!
I'm kind of dissapointed right now :(
I've got a FolderBrowserDialog in my form, and it works fine, until I choose
a path that is over approximately 135 characters long. Then it crashes the
entire app. (Haven't got the exact count, but it works with ca. 130)
Is this behavior by design, or is it a bug? Anyway, it's really annoying.
The error that occurs is the following:
An unhandled exception of type 'System.Runtime.InteropServices.COMException'
occurred in mscorlib.dll
Additional information: Invalid access to memory location.
Any help appreciated!

' Clear all text from the RichTextBox;
rtbSetUpInstructions.Clear()
' Set the font for the opening text to a larger Arial font;

rtbSetUpInstructions.SelectionColor = Color.Orange
rtbSetUpInstructions.SelectedText = "Oranges" + ControlChars.Cr
rtbSetUpInstructions.SelectionFont = New Font("Arial", 12)
rtbSetUpInstructions.SelectionColor = Color.Purple
rtbSetUpInstructions.SelectedText = "Grapes" + ControlChars.Cr
' End the bulleted list.
rtbSetUpInstructions.SelectionBullet = False
' Specify the font size and string for text displayed below bulleted list.
rtbSetUpInstructions.SelectionFont = New Font("Arial", 16)
rtbSetUpInstructions.SelectedText = "Bulleted Text Complete!"
Am I missing anything. I haven't done any modifications to the original code.

- Dotnet >> Dot Net Components Reviews?Folks,
Perhaps, this is a very commonly asked question. Pardon me for not being
attentive before. Is there a website/resource where I can get some reviews
on Dot Net 3rd party components. Until VB 6.0 days, I did not care if
Mabrys and Dev-Softs charged 100-150 for their suite of products and they
turned out to be lemons. However, in the dot net world, when I have to
shell out $400+ for the components, I just want to make sure, I am making
the right choice.
Any help will be greatly appreciated.
Regards.

- Net Framework >> Discovering exception thrown by a methodHello all,
I would like to know if there's a way to discover what exception(s) is
thrown by a function. I can imagine it is possible using reflection, but I
cannot find it.
For example:
toto instance of class Toto.
toto.myFunction(); // inside myFunction some exception are thrown, this is
what I try to figure out...
Thanks in advance.

Winforms >> Question on ClickOnce Deployment
If you are using click once then just publish the exe after you made your
changes.
In other case you need to deployee the assemblies in which includes the code
change. Moreoevr you also need to take care in case you didn't made any
changes in a particular assembly but assemblies its is referring.

- Visual C#.Net >> How to make SoapHttpClientProtocol create different TCP connection for web service invocation?I use VS auto generated code to invoke a internal network webservice.
The auto-generated code use class SoapHttpClientProtocol to do Soap-on-
http communication. It turns out that for single
SoapHttpClientProtocol instances, TCP connection is always maintained
for reuse. This is understandable. Now, I have one load balancer
between client and backend webservice cluster, so, single TCP
connection for single invocation is prefer-ed.
How to make it create TCP connection for one method invocation and
then close it?
Thanks,

- Visual C#.Net >> Alternative to 'abstract' in base forms?I'm creating several forms that inherit from a base form. I want to require
the derived forms to implement certain methods of the base form. The easy
solution would be to declare abstract methods in the base form. But I can't
do that, since the WinForms Designer can't instantiate an abstract form.
So, what would be a good alternative to using abstract methods. I'm thinking
about declaring an interface, but that seems kind of klunky. Thanks.

- ADO >> Progress bar doesn't incrementI created a windows form that has a progress bar on it. I am running a bunch of statements to update data on the database. I want the progress bar to increment (perform one step) after each update. The problem is that the progress bar doesn't move (it just sits there until the end) can anyone give me an example of how to accomplish this?
example:
progressBar1.Visible=true;
progressBar1.Show();
progressBar1.Maximum = 24;
progressBar1.Step = 1;
progressBar1.PerformStep();
Perform_update1;
progressBar1.PerformStep();
Perform_update2;
progressBar1.PerformStep();
Perform_update3;
etc.
thanks in advance

- Microsoft Project >> Material Cost Input and CalculationOur Material Cost View is not acting consistently and am wondering if anyone
knows what the reason and/or fix might be.
In some instances it is working as desired where once the material resource
is assigned to a task you must enter the units into Actual Work then Actual
Cost is calculated. Entering directly into Actual Cost is blocked.
In other instances it will block from allowing input into Actual Cost on the
first input column then will allow it after that. If data is input into the
Actual Cost field Actual Work is not calculated and the 2 become out of sync.
In even other instances it allows input into Actual Cost on the first try.
The problem does not seem to be project specific either. Sometimes it works
OK on a project and other times it doesn't. I have not been able to identify
any commonality in occurance.
Thanks,
Debbie

- Microsoft Project >> Resource across projectsI'm getting there - thanks to this forum!
I now have a shared resource across 3 projects (one of which is absence,
i.e. sickness & holidays!)
If I open my resource file (in resource usage view), I can see by person,
all the work that they have done across the projects in a week (to make sure
it adds up to 35 hours) then by project I can see the progression - LOVELY
But, of course, a problem remains (!), since I receive worksheets (across
the projects) by man, I would like to be able to enter the hours worked from
the resource usage view in the shared resource file, and then have that
update the hours worked in all the projects (and consequently hours remaining
etc etc) - I don't seem to be able to do this (it doesn't have any effect,
and will not save), I have to go into each project & update them individually
(which then updates the shared resource file)
I'm sure there must be a way of doing this, all help appreciated
Thanks

- Visual C#.Net >> Calling a parent class methodI have a class (sharedClass) that is instantiated (not derived) by two other
classes (guiClassA and guiClassB). The sharedClass needs to be able to call
a method that is defined in its parent class (guiClass).
Specifically, when guiClassA or guiClassB calls a method from the
sharedClass, the sharedClass needs to log its actions by sending strings to
the guiClass (via guiClass method calls), which in turn display or record
this log information in their own unique ways.
How can the sharedClass call out a function from its parent class without
knowing exactly what kind of class the parent class is? (I can however
guarantee that the parent class will implement the logging function).
Since both guiClasses are not used in the same application, I was able to
solve this in C++ by declaring the logging function prototype in a header
file that was included by all the classes, and then defining the function
implementation at the same level as the guiClass was instantiated. Thus, the
connection was made by the linker. Is there any way to do something similar
in C#?

- ADO >> improving executenonquery timesHi,
We are new to ADO.NET, and any help would be appreciated.
The scenario is as follows: we have a large number of objects
(thousands) to write to a database. Each object has a method that
returns the SQL query which will update a relevant table in the
database.
We had opened a connection to the databse, and for each such string
did executenonquery (on that one connection). The results were
horrible. Then we had moved on to aggregating all the queries,
separated by newline in a one huge string (with StringBuilder of
course) and doing only one executenonquery per all the objects - that
was a big improvement.
Is the paradigm of doing one large executenonquery instead many small
ones, for one connection is indeed optimal ?
Is the paradigm of having one connection (instead of say, thousands,
each per object) optimal ?
Do you have any idea how the times may be improved further ? Is there
any other method ?

- Net Framework >> Re: Question on ConfigurationElementCollection designA while back, a question was posted on ConfigurationElementCollection design as follows:
"I have 2 questions on using element collections when building a custom
section handler. I'm using the "declarative" model and I can post the code
if necessary.
My code works and the XML in app.config for my custom section looks like this:
MySection name="x"
Stores add name="store1"
add name="store2"
Stores
MySection
But I have 2 sort of "cosmetic" questions about changing the XML:
1.
...
2. In some cases it might also be nicer to skip the outermost "Stores"
element and just have this:
MySection name="x"
Store name="store1" Store name="store2"
MySection
But I don't see how to arrange for this in the declarations of a
ConfigurationElementCollection. It seems to require the outermost element to
key on its name. What I want is sort of an "unnamed" collection of Stores."
The first part of the question was answered by using the ConfigurationCollection attribute.
Did you ever get a solution to the "unnamed" part (part 2) of your question? I'd like to also add a section collection to my config section and adding a name is redundant. ie., the "Stores" element in you sample. Can an "unnamed" section be added?
