Hi,
Please help me in derefernce a variable in VisualBasic or VBScript.
|

It's not directly possible to dereference a variable in Visual Basic, but you can do a workaround with the help of the api-function "rtlmovememory" (copymemory). This function makes it possible to copy the data of the variable when only having its adress (varptr-function in VB; some api-functions only return pointers to datastructs).
Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" _
(hpvDest As Any, ByVal hpvSource As Long, ByVal cbCopy As Long)
This function copies the value of a variable into another variable of the same size (hpvDest). The second parameter takes the adress of the sourcevariable. The third parameter takes the size of the variable.
I think there is an example of this technique in the Knowledge Base...

I have a requirement to detect when an application is launched and to determine if the application was launched by an existing application.
For example, when you create a new mail message in Outlook, Outlook actually launches a new application to allow you to edit & send the message. I can detect that a new application has been launched but there doesn't appear to be any way of determing that the application was launched by Outlook.
Any suggestions?

The following code uses the Scripting.FileSystemObject to rename the file specified in strFilePath to the format out mm-dd-yyyy.txt . Ex. for today, the file would be named
04-23-2001.txt
Hope this helps
Dim strFilePath As String
Dim strNewFileName As String
Dim fso As FileSystemObject
Dim file As File
strFilePath = "c:\myText.txt"
strNewFileName = Format(Now(), "mm-dd-yyyy") & ".txt"
Set fso = New FileSystemObject
Set file = fso.GetFile(strFilePath)
file.Name = strNewFileName
Set file = Nothing
Set fso = Nothing

Hi,
I need to write a function which takes special characters(ascii characters) eg: sm,Tm and convert them to HTML String.
I need to use VB to write this function.
Please help me with this.

I would use the split command to find the text that you are trying to replace. I'm sorry, but if I could see a few of your lines from the file I think that I could start the function for you.
I hope that you have found away to do this by now.

This may be a dumb question:
I have the variable Port of type integer declared in a module like this:
Dim Port as Integer
(in general declarations)
I then have it declared in each of my forms like this:
Dim Port as Integer
(in general declarations)
How do I pass the value of Port in my main form (frmMain) to another form called from frmMain?
David.

First of all, you have to change the declaration of Port from Private (Dim) to Public. Then you can just reference the variable using the form name. Ex:
form1.Port = frmMain.Port.
Hope this helps

You dont even have to declare it on each form. Just reference the one in frmMain as illustrated
by Jason.
Make it local to the function you are using it in
Private Sub cmdDoStuff_Click()
Dim iPort as Integer
iPort = frmMain.Port
' etc.
End Sub

I have a Variable Problem, that is being fill but I can't read it
I'm sending the variable to a DLL which is declared;
Private Declare Function GetList Lib "C:\Program Files\Microsoft Visual Studio\MyProjects\API\Debug\API.dll" _
(ByVal pszSch As String, ByVal pszQualifier As String, vNumber As Variant, ByVal pszMessage As String) As Long
The Function that calls this DLL is;
Private Sub Command1_Click()
Dim xStatus As Integer
Dim pszSch As String
Dim pszMessage As String
Dim pszQualifier As String
Dim vNumber As Variant
ReDim vNumber(2002) As String
pszSch = "TEST"
pszQualifier = " 'COM_NUM' = 123"
pszMessage = Space$(255)
xStatus = GetList(pszSch, pszQualifier, vNumber, pszMessage)
MsgBox vNumber(x), vbInformation, "vNumber"
Text1 = vNumber(x)
The MsgBox line with the vNumber will display the value in the variable
But the Text1 line shows nothing for the variable
What do I do to read this variable without the message box ?
thanks

|
|

I hope that this will work
Text1.Text = trim(cstr(vNumber(x)))
since the return variable is Variant type, before getting its value to the text box convert it into text type.

I would say that if vNumber should be a numerical value, explicitly cast it to what you need it to be. It is probably turning into a string. Set a breakpoint at the MsgBox line and set a watch on vNumber(x). That will probably help you determine how the data is kept and what you need to do with it.
Text1.Text = CInt( vNumber( x ) )
By the way, is x declared elsewhere?
