    - 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 General Hideable Panel Visual Basic

When I start the application and work with it for a while it somehow disappears from the taskbar.To get the Application button back on the taskbar I use Alt+Tab to switch to the application and voila,.. the taskbar button is back.

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 General Hideable Panel 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 General Hideable Panel Visual Basic

    - How do you manage your controls if there are many many controls placed on the forms? You can also create a user control, I have created ones that have over 100 textboxes, about 75 labels, 50 check boxes and runs calculations based on information entered into the text boxes and the check boxes that are checked. Once you create the control, you can bring it into the application and the controls in the user control will be...bound I guess I would say, to the user control. This has really helped me manage these huge items. The best part, if I have to change something on the user control, I am looking at that code, and pretty much, just that code, not trying to sort through code that is partially irrelevant to the control.

    - Background Worker I seem to have a semi-unique situation. I have to procedures that run in my program that last for a specific time frame (using the timers). The good news is, the timers work great! The bad news is I am having to use While (or do until) loops as other things are happening during the time frame. These loops utilize 100% of the processor time killing off the ability of the program to do the other functions. Shy of putting in "MsgBox" commands to force the processor to pause, I wanted to try using the background workers to process the while loop. This would work great except now my program doesn't wait for the events to complete before continuing on with the program. As the first loop is dialing a phone number and then waiting for an answer or call failure or dialling time out, I do need for the program to wait until one of those events occurs. How can I get the program to wait on the background worker to finish without adding yet another while loop I tried to have the background worker act as a function, but VB does NOT like that at all. I had figured that if I did a variable=start.backgroundworker() the program would wait but not kill my computer for all the other commands. Can someone please point me in the right direction on this I am really at a loss on how I can use the ASYNC in the background but still wait on the ASYNC process to complete before continuing. Thanks. Tag: Visual Basic General Hideable Panel Visual Basic

Re: Visual Basic General Hideable Panel

Frank Carr

MyPanelControl.Visible = False to hide it, = True to show it. Just put the code to toggle it in your button's click event.

Re: Visual Basic General Hideable Panel

I used radio button but you could do the same thing using button with image (Small Triangle)....

Code Snippet

Private sub Radiobutton1_Click(byval.......................... the click event

me.panel1.visable = false

me.radiobutton2.visable = true 'Made this visable so the user can click on it to make it reappear... in your case just change the image to show the pannel holds some thing...

end sub

Private sub radiobutton2_click( ..................... other click event

me.panel1.visabe = true

me.radiobutton2.visable = fales

end sub

Re: Visual Basic General Hideable Panel

cybertaz69

Easyest way is to add a button with image and no text..... To make it look Pro add a groupbox inside the panel with the button out side the groupbox...

Re: Visual Basic General Hideable Panel

SJWhiteley

An alternative that I've used is to use a TableLayout control: you can 'hide' a panel by changing it's width (or height) of the row or column that it's in to zero. All the other rows/columns as appropriate will resize.
