 - Winforms >> Huge Memory UsageHello all,
 I am writing an application in C#, VB.NET which basicaly
 has a form with a few pictureBoxes on it and a TabControl
 with 3 tab pages - in each one a treeView and a ListView.
 In addition it loads a few other dll's as a reference
 which should not be memory consuming since each have a
 few simple classes.
 The thing is - this application can take up to 40,000KB
 of memory!!!
 Any idea where to start checking? How can I debug and see
 what part of my application is responsible for such
 memory usage?
 
 One more thing: I did some tests and noticed that even a
 simple form with nothing on it can take up to 15,000KB ,
 am I doing something wrong???
 
 Thanks,
 
 Haim.

 - Net Framework >> Feature request:....When setting the [Flags] attribute on an enum, why should I have to specify
 powers of 2 when the compiler should see this is a bitfield and set the
 range accordingly, why should I have to do the work that the compiler can
 do?
 
 To me this is just asking for errors to be introduced by offloading this
 responsibility onto the programmer.
 
 Sure we should be able to override a value in the bitfield enum to allow
 ranges like All = Enum1Val | Enum2Val; etc.

 - Winforms >> Opening a child form from another child formHi
 
 I have this sub in a main form;
 
 Sub OpenForm(ByVal x As String)
 Select Case x
 Case "1"
 form1 = New frmClients
 form1.TopLevel = False
 Me.FormsPanel.Controls.Add(form1)
 form1.Show()
 form1.BringToFront()
 Case "2"
 form2 = New frmContacts
 form2.TopLevel = False
 Me.FormsPanel.Controls.Add(form2)
 form2.Show()
 form2.BringToFront()
 End Select
 End Sub
 
 I first call the sub in the main form as OpenForm("1") which creates the
 first child form1. Now in form1 I call the same sub as;
 
 dim frm as new frmMain
 frm.openform("2")
 
 Now even though the sub is called and code is executed, form2 does not
 appear on top as needed. What is wrong and how can I make form2 appear from
 within form1? Form1 & form2 are both child forms to the main form which
 contains the sub OpenForm.
 
 Thanks

 - Dotnet >> Converting dates with CultureAndRegionInfoBuilder ?Hi,
 the built-in CultureInfo in .NET 2.0 can convert calendar dates
 between cultures
 for instance this code shows current time in hijri calendar
 (arabic culture) :
 
 CultureInfo pcul = new CultureInfo("ar-SA");
 MessageBox.Show(DateTime.Now.ToString("F", pcul));
 
 it seems that MIcrosoft has not developed this feature for all
 CultureInfos
 for example :
 
 CultureInfo pcul = new CultureInfo("fa-IR");
 MessageBox.Show(DateTime.Now.ToString("F", pcul));
 
 must return the current date in persian calendar (jalali date) but
 it retrurns the
 Georgian calendar date time.
 is there anyway to override this routines in .NET 2.0 ? (it was
 possible in .NET 1.1)
 
 I found CultureAndRegionInfoBuilder class to build new cultures but
 I found nothing
 about date conversion routines.
 
 Thanks,

 - Dotnet >> Need two views for a datalistI have a datalist that displays catalog items on the page 4 in a row
 using the RepeatColumns="4" and RepeatDirection="Horizontal" the page
 displays two rows of data when first viewed and if there is more then 8
 products to display will create page numbers at the top of the page for
 each subsiquent page of 8. The customer has asked to place an image in
 the area occupied by the first two columns in the first row, but only
 on the first page. The image information is not stored in the database
 with the product information. I need to alter the template for the
 first page only in some way to show this new layout and i'm stuck. Any
 help or direction would be appreciated. Is this even possible?

 - Winforms >> Smart Client with dynamic app.configI am deploying a smart client app via ClickOnce. The config file gets
 deployed along with the application. However, once trying to edit the
 config file after deployment, the application no longer works because
 the manifest detects a change in the file.
 
 The app.config contains the path to a web service. I need the
 app.config to be dynamic so that when the app is deployed to various
 locations, I can change path.
 
 I do not want to pass the URL via the query string.
 
 Other than creating an external file with the settings, does anyone
 know how I can create a dynamic app.config?
 
 Thanks,
 Dave

 I have projects in Project Server 2003 that are grouped within an RBS

 about setting this up?

 - Visual C#.Net >> Not a Question - Anyone tired of guessing types coming from a database?Try this instead:
 
 // T - the type you are attempting to retrieve.
 // o - the data that you want to turn into a T
 T get<T>(object o)
 {
 // handle nulls - turns Nullables into null, reference
 types to null and value types to 0.
 if (o == null || o == DBNull.Value)
 {
 return default(T);
 }
 // we have real data so cast it
 else
 {
 // Gets the underlying nullable type. Null if the type
 is not Nullable.
 Type t = Nullable.GetUnderlyingType(typeof(T));
 
 // ChangeType is especially nice for dealing with
 casts.
 // Where explicit casting fails, ChangeType often
 succeeds.
 // It is dangerous to convert from Object to
 Nullable directly, since Object may not be a U.
 // However, from U to Nullable always succeeds, so
 make Object into U first.
 // Since we already handled nulls, we need not worry
 about casting away null-ness.
 return (T)Convert.ChangeType(o, t == null ?
 typeof(T) : t);
 }

 This generic method allows you to send in whatever type you desire to
 pull off as T. This method will do its best to take what is on the
 database and turn it to your type.
 
 It even handles Nullable types so you can put nulls into numbers and
 dates.
 
 It will return nulls into the default value of your type, so numbers
 become 0, Dates become DateTime.MinValue and reference types become
 null.
 
 This is absolutely necessary to provide an efficient, universal and
 safe way of managing data types for business objects, especially if
 your DBAs like to change precisions on your a lot.
 
 I have been using this code for months now and have been pleasantly
 surprised how little I have to worry about guess work anymore.
 
 Let me know if you find any problems with it. Like I said, we have
 gone months without any issues at all.
 
 Cheers,

 - Winforms >> Clipboard - custom format bug?I want to put a custom object in clipboard and later to be able to extract
 it. I had red the Charles Petzold book "Programming Microsoft Windows with
 C#" at chapter Chapter 24. In Petzold book I have read that is possible to
 put a
 reference to a custom type in clipboard and later you are able to read it.
 As an example was shown how to put a System.Windows.Forms.Button class in
 clipboard. I tried this but it doesn't worked.
 I also tried to do this with a DataRow that also have Serializable attribute
 
 For details see code bellow.
 
 using System;
 
 using System.Windows.Forms;
 
 namespace TestClipboard
 {
 /// <summary>
 /// Summary description for Class1.
 /// </summary>
 class Class1
 {
 /// <summary>
 /// The main entry point for the application.
 /// </summary>
 [STAThread]
 static void Main(string[] args)
 {
 System.Threading.Thread.CurrentThread.ApartmentState =
 System.Threading.ApartmentState.STA;
 
 System.Data.DataTable dt = new System.Data.DataTable("Test");
 System.Data.DataRow dr = dt.NewRow();
 Clipboard.SetDataObject(dr);
 
 IDataObject dataObject = Clipboard.GetDataObject() as IDataObject;
 if(dataObject != null &&
 dataObject.GetDataPresent(typeof(System.Data.DataRow)))
 {
 object fromClipboardAsObj =
 dataObject.GetData(typeof(System.Data.DataRow));
 // here the extracted object is null
 
 if(fromClipboardAsObj != null)
 {
 // this is the path that program should use.
 // Unfortuantely is not using this.
 System.Diagnostics.Trace.WriteLine("fromClipboardAsObj != null");
 }
 else
 {
 // this is the path code that program is following.
 System.Diagnostics.Trace.WriteLine("fromClipboardAsObj == null");
 }
 
 }
 }
 }
 }
 
 Please let me know if I'm wrong and where I'm wrong.
 Same thing is happen by replacing DataRow with Button
 I used visual studio 7.1 with .NET Framework 1.1.4322 SP1
 
 Same source-code work as I expected on .NET 2.0.4115
 that comes with vs2005 December CTP
 
 If this is a .NET Framework 1.1 bug where shoud I report it
 and what is the workaround?

 I want to move printjobs from one windows 2003 queue to another.
 This far I have the following code:

 Dim jobs1, jobs2 As ActiveDs.IADsCollection
 Dim job As ActiveDs.IADsPrintJob
 
 queue1 = GetObject("WinNT://server/printer1")
 queue2 = GetObject("WinNT://server/printer2")
 
 jobs1 = queue1.PrintJobs

 How can I move the jobs from printer1 to printer2?
 I tried to achange the property job.HostPrintQueue, but that one is
 ReadOnly.

 - Visual C#.Net >> Dependency Injection - Can It Be This Simple?Does the following accurately summarize the notion of "dependency
 injection?"
 
 Class A needs to cause "Some Activity" to happen (in addition to other
 things that Class A does).
 
 Class A may or may not have a default implementation of Some Activity.
 
 Class B is able to do Some Activity.
 
 At runtime, a reference to an instance of Class B is passed to Class A
 (perhaps via Setter, or to the constructor of Class A).
 
 Class A causes Some Activity to happen by calling a method of its Class B
 reference.
 
 In the future (or even immediately), we need for an alternative
 implementation of Some Activity, so we create Class C.
 
 We can then pass a reference [to a Class C instance] to Class A, which then
 initiates Some Activity on the Class C instance.
 
 In the above account, Class B and Class C both implement an interface or
 derive from a common abstract base class -- and Class A knows only about
 that interface, and initiates Some Activity as a method of that interface or
 base class.
 
 The most important benefit of the above arrangement (dependency injection)
 is that we can extend the application specifically to perform alternative
 implementations of Some Activity by adding a new class and updating the
 application configuration (so that Class A can be passed a reference to the
 new class), without modifying Class A in any way. In other words, Class A is
 open for extension, but closed for modification, and dependency injection is
 one way to achieve that objective.
 
 Your comments are appreciated, as I'm wanting some verification or
 clarification of my understanding of dependency injection.
 
 Thanks.

 - Microsoft Project >> How do I filter for Overallocated Tasks in Project?Hi,
 
 I'm beginning to level my resources, but I first want to know which tasks
 have overallocated resources assigned to them so I can decide what priority
 level to give them before leveling the project.
 I first tried to set a filter for task overallocations, but that doesn't
 help since only overallocations for the individual task show up (in my case
 none, because, although during any given day there may be three tasks
 assigned to Bob totalling 24 hours-- a definite overallocation-- each
 individual task is not overallocated at 8 hours).
 I also tried to filter for resource overallocations but that didn't help
 since 1) it only works on resource views and, 2) it simply highlights the
 resources which are overallocated without giving you a list of the tasks
 which are creating the overallocations.
 Finally I tried messing around with a custom filter but wasn't able to find
 the right combination of fields and values to give the desired results.
 If anyone has any suggestions I would really appreciate it.
 
 Thanks,

 - Net Framework >> Install a Service Programmatically ?Hi there,
 
 I'm designing an application in C#. One of the files in my application
 is "server.exe". This assembly listens for inbound connections and handles
 various incoming requests. I want to give the user of my application the
 option to allow server.exe to execute and handle requests even after the
 user has logged off.
 
 My plan is to ask the user "Would you like this service to continue
 running after you log off?". If the user answers yes, I want to install
 "server.exe" as a service. I've done this successfully in a manual way using
 the 'installutil' .NET helper application, but my application will need to
 do this in an automated way.
 
 How can I accomplish this? Shall I shell out to a command prompt and
 execute installutil against server.exe? Does the user need to be an
 administrator of his machine? Can I be 100% certain that if the user has the
 .NET framework installed that 'installutil' will be installed as well? If
 so, how do I find it? Is there some sort of macro (i.e. %DOTNET_FOLDER% for
 example) that will allow me to easily determine the dotnet folder where
 'installutil' resides?
 
 Is there any way to get server.exe to execute after a user has logged
 off *other* than using a service? I'd appreciate any suggestions.

 - Dotnet >> How can I see what's in a collection during debugging?
 
 Hello,
 
 Can someone tell me how I can view the contents of a collection when in
 debug mode?
 
 For example, I working with a dataset and when the app stops at a breakpoint
 I'd like to see what is actually in the Tables collection of the dataset. I
 add a watch on my dataset variable and expand the Tables object. It just
 keeps showing me the following: Count, IsReadOnly, Is Synchronized, Item and
 SyncRoot. Expand SyncRoot and you're at the beginning of a big old
 recursion.
 
 So if I want to see what's in row x of table y for example, I have to create
 a variable in my code representing that row in that table and add a watch
 for THAT variable. I have to believe that there is an easier, more dynamic,
 way for me to inspect the content of this during debugging.
 
 Any help would be greatly appreciated.
 
 David.

 - Visual C#.Net >> Isolated Storage bug at design timeHello,
 
 We use several user controls and derived custom controls. Some of
 which actually hit the database at design time to show data (such as
 filling a list box, etc...)
 
 Our c# client server app uses the .NET Isolated storage libraries for
 storing connection string and other info about the application. The
 problem is that the Isolated storage bombs at design time (when you
 try and view a control that hits the database at design time).
 
 The workaround we have in place is the Isolated storage check is in a
 try / catch. If it fails, we load a hard-coded xml file with the same
 settings at a specified path that never changes... which defeats the
 whole purpose of Isolated Storage.
 
 This isn't a huge issue cuz it only happens at design time and we have
 a (hackish) workaround, but I was wondering if anyone has had this
 problem and/or knows why it would be happening?
 
 Thanks,
 Dave
