    - TypeOF doesn't work correct for Interfaces.. Hello I have a "Baseclass". This "Baseclass" implements two interfaces. In the WinApp i try to check with "TypeOf" for the used interface.

    - Convert VB script to C# Hi all, I have the following code for testing WMI for a driver. I got these vbs samples from OSR and was wondering how to port these to a C# application. Code Snippet Set fso = CreateObject("Scripting.FileSystemObject") Set a = fso.CreateTextFile("nothing.log", True) Set Service = GetObject("winmgmts:{impersonationLevel=impersonate}!root/wmi") Rem Nothing_Statistics - Set enumSet = Service.InstancesOf (" Nothing_Statistics ") a.WriteLine("Nothing_Statistics") for each instance in enumSet a.WriteLine(" InstanceName=" & instance.InstanceName) a.WriteLine(" instance.TotalIrpCount=" & instance.TotalIrpCount) a.WriteLine(" instance.TotalIrpRate=" & instance.TotalIrpRate) a.WriteLine(" instance.WmiIrpCount=" & instance.WmiIrpCount) next 'instance I read that you need to add a reference to System.Management in your project to start with, but that's as far as I can go. The "Nothing_Statistics" is a class defined in a MOF file for the driver. "TotalIrpCount","TotalIrpRate" and "WmiIrpCount" are all members of this class as defined in the MOF file. Could you please help me in progressing further with this Any pointers to where I should look for samples is gr8ly appreciated...Thankx. Tag: Visual Basic Language VB.Net/Crystal Reports Visual Basic

    - Store RTF text as string on clipboard? I have some data in a DataTable, including a column of RTF (Rich Text Format) data. I wanted to be able to create a comma or tab-delimited string which I could then put on the clipboard, and then retrieve back later on or send it to Excel. I used a StringBuilder to 'build' the text string. What happened, though, is that after the first string line was created (separated by a carriage return/line feed), I added additional lines but they never show up when getting the string back via the StringBuilder ToString. I checked the data length of the string as I was building it, and it did increase constantly in size; however, only that first record would show up on the display and when I did the ToString. This also occured even if I did a plain old concatenation via & or Concat. I -THINK- it has something to do with the RTF field being placed on the string - it almost seems that after the first one is placed no other strings are displayed (even they the length says they are being added). So... The real question is: If I have to build a string that is composed of multiple RTF fields, how do I do that Thanks. Chimp (Tom) Tag: Visual Basic Language VB.Net/Crystal Reports Visual Basic

    - Stacktrace tab gone Using VS05 Pro SP1... I have lost the stack trace tab that is at the bottom of the debug screen while debugging that shows you the stack strace when you hit a break point. I don't see how to make it re-appear. Any suggestions I don't see anything in the View option that would do it. Also, how do you remove tabs from the bottom or right that you don't use I don't see anyway to remove them. Thanks! Bob Tag: Visual Basic Language VB.Net/Crystal Reports Visual Basic

    - Convert Delegate Hi, I hope this is the right place to post this. I found on www.netfx3.com a sample workflow application and it has a section of code that was written in C#, we need it in vb. I have worked with delegates before, but never like this.. Dictionary < string , Activity > activityIdToActivity = new Dictionary < string , Activity >(); Walker walker = new Walker (); walker.FoundActivity += delegate ( Walker skedWalker, WalkerEventArgs eventArgs) { Activity activity = eventArgs.CurrentActivity; activityIdToActivity.Add(activity.QualifiedName, activity); }; walker.Walk(root); My questtion would be, how would i do this in VB. If you would like to see all the code download the sample from here http://wf.netfx3.com/files/folders/sample_applications/entry4074.aspx , Where i'm talkin about is in the WorkflowAdminService Project...ClassesRemoteFromHost.vb..Line 965...

    - Use of VB 2005's ImageList Upgrading from VB6 From my side of the World, Good Evening to You All!! I' m asking your assistance once again regarding upgrading from VB6, this time I' m enquiring about the use of ImageList. I was instructed to upgrade from vb6 the following: Case 0 Image1.Picture = LoadPicture("c:\animals\gorila.bmp") Case 0 PictureBox1.Image = New Bitman("c:\animals\gorila.bmp") And it works perfectly but as VB 2005 provides the ImageList I assume that will be tydier especialy on transporting.

    - Mask: optional but no spaces. Number or numbers only textbox entry. For what it sounds like your doing and you want to simply validate that the textbox has a numeric entry in then you can do this with a normal textbox. You'll probably want to restrict the textbox to enter numbers only and there are numerous examples of how to do this in the VB forums - search for textbox and numbers only. This simple code validates that a number has been entered and that it is within a specific numeric range. This would allow decimals to be entered which may not be desirable and adding the numbers only code would prevent the addition of decimal places limiting the numbers to integer only. Masks are good if you have a fixed format and not a variable one. ie. zip codes are always 5 digits long. Social Security Numbers are 9 digits in specific format. Public Class Form1 Private Sub TextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged Dim Tb As TextBox = CType(sender, TextBox) If IsNumeric(Tb.Text) = False Then MsgBox("Please enter a number!!") Else Dim x = CType(Tb.Text, Single) If x < 0 Or x > 100 Then MsgBox("Out of range") End If End If End Sub End Class Tag: Visual Basic Language VB.Net/Crystal Reports Visual Basic

    - thread timers and garbage collection I have created and started a thread timer in the application event sub "myapplication_startup" using the following code: Dim TheThreadTimerStateObj As New ThreadTimerStateObj Dim TimerDelegate As New Threading.TimerCallback( AddressOf TheThreadTimerStateObj.ThreadTimerTask) TheThreadTimerStateObj.TimerReference = New System.Threading.Timer(TimerDelegate, TheThreadTimerStateObj, 5000, 5000) And here is the object definition: Public Class ThreadTimerStateObj Public TimerReference As System.Threading.Timer <irrelevant code not pictured> Public Sub ThreadTimerTask( ByVal ThreadTimerStateObj As Object ) <...bleah bleah...> End Sub End Class I stored a reference to the new System.Threading.Timer object (created by the 3rd line of code) within my ThreadTimerStateObj class so that the garbage collector wouldn't destroy the new timer after I exited the sub, and it seems to be working. THE QUESTION: Must I also save a reference somewhere to the new ThreadTimerStateObj object "TheThreadTimerStateObj" to prevent it from eventually being destroyed, or is a reference already being saved internally somehow when TheThreadTimerStateObj.ThreadTimerTask is passed as an argument to create the new System.Threading.Timer Tag: Visual Basic Language VB.Net/Crystal Reports Visual Basic
