    Create PDF to Allow Elctronic Signature

    How are you creating the PDF, with a library or something? I used to rock and roll every night and party every day. Then it was every other day. Now I'm lucky if I can find 30 minutes a week in which to get funky. - Homer Simpson Arrrr, mateys! Ye needs ta be preparin' yerselves fer Talk...

    How many child SDI forms are open in a parent MDI form?

    It seems you should do this in the code that opens the child form, not in the child form's load even handler. For example, say this is the code to open a new child form, FormChild, from the parent: Dim frmChild As FormChild frmChild = New FormChild 'here, Me is the MdiParent For Each loForm...

    How to prevent vertical flickering while moving a form at runtime?

    I'm sorry, I wasn't clear before. You *should* set Me.DoubleBuffered = True - it might help with the flickering. Set it in Form_Load, before anything else. I used to rock and roll every night and party every day. Then it was every other day. Now I'm lucky if I can find 30 minutes a week in...

    Is there equivalent in VB .NET to the VFP'S ADDBS()?

    Take a look at the String.EndsWith function. As to your function: ' Parameter's verification If VarType(tsPath) <> VariantType.String Then MsgBox("Invalid parameter passed: " & Chr(34) & "tsPath" & Chr(34) & " must be of type String", MsgBoxStyle.Critical, "Fatal Error: INVALID PARAMETER")...

    Error &quot;Variable 'loStreamReader' hides a variable in an enclosing block&quot;

    The problem is occurring because you're *declaring* 2 variables with the same name. So, Using may destroy the *object* created by the declaration, but the declaration still exists. There's no way around this other than using different names in the declarations. Or, just use one declaration...

    Re-declare/re-use local memvar - How-To?

    This should work: ReDim lcBuffer(2^14) This will clear any data already in lcBuffer. If you already have data in lcBuffer and want to keep it use the Preserve keyword: ReDim Preserve lcBuffer(2^14) Also, trying to read more than 14 chars into the buffer (before the ReDim) will result in an...

    Is there a replacement for Public memvars?

    Environment is not read-only. Use Environment.SetEnvironmentVariable(variable As String, value As String) to set an Environment variable. Use Environment.GetEnvironmentVariable(variable As String) to retrieve. I used to rock and roll every night and party every day. Then it was every other...

    Is there a replacement for Public memvars?

    If all you want is to distinguish between IDE and EXE runs, what I do is set a command line argument in the project properties, then do a check to see if there are any command line arguments when the program starts. If there are, it's in the IDE. To do this: Go to the PROJECT menu, then select...

    How to prevent vertical flickering while moving a form at runtime?

    Well, DoubleBuffered is indeed a property of a Form object. The mouse-over text of DoubleBuffered reads: "Gets or sets a value indicating whether this control should redraw its surface using a secondary buffer to reduce or prevent flicker." Here's a couple of links I found...

    First, create the handler code for the ToolStripMenuItem's Click event: Say it's named RecentFilesMenu, so use Private Sub RecentFilesMenu_Click(Sender as Object, e as EventArgs) 'code here End Sub Then, in the form's Load event, put the AddHandler code: AddHandler...

    Parameter data type verification in VB .net

    You could put a Try...Catch block around the call to the function: Try MyFunc(123, "String") Catch ex As Exception MsgBox(ex.Message) End Try You can get a lot of information about the exception thrown via the Exception object (ex). In the Catch code you can take various actions, like logging...

    Throwing Exception

    The purpose of throwing an Exception like this is to halt processing of the code and return the Exception to whatever procedure called this code. When the exception is thrown, it stops processing at that point and returns the Exception object to the calling code. If that code has a Try...Catch...
