Hi,
I am trying to run Visual C++ stand alone executables in Visual Basic. The Visual C++ executables read in text files and load pictures from the folder in which they are located. When I try the shell command within VB it runs the executable but does not load the text files or the pictures. I also tried using an html link and had the same problem with the files not loading. Help!?
Thanks in advance!

AS for your html link
are you using Vb 6?
if so, you can do this
ShellExecute Me.hWnd, "Open", "PAth to File\Doc.html", "", "", 1
put this into a Click event
Help is great only if you ask correctly

Ho wif i wan to make C# and VB6 send strings of text to each other on a network is this possible...how?
i'm lost plss guide me thanks

Is it the C++ program that isn't loading the text/picture files? Is the C++ .EXE in the same directory as your VB app? Are the data files in the same directory as the C++ app or are they in the directory with the VB app?

I have tried putting them in the same directory as the VB app as well as trying an absolute path "C:\colorfill.jpg" and "C:\helpfile.txt" and it did not import the files. Any ideas? I am concerned that the recent Windows upgrade for security issues has disabled this ability because I could swear it worked not long ago. Any ideas?
Thanks,
Chris

IMPORT? 
What are you talking about? What does your code look like that does the shell thing and what EXACTLY is it supposed to do?

I found the problem, your last response made me go back over where everthing was. You were right that if all the resource files were not in the same folder as the vb project it would not work. That works now! The html calls still do not work but I believe that is because the html is being run by another exe. Thanks again for your help!

hi all ihave 2 questions
# 1 I have a application that allows users toswipe their ID badge to log them into or out of a system. problem is, i put this code into the text_Change () event. which works fine. BUT if the user forgets their badge, i also have it set up to allow them to enter a password so they can manually log their selves in or out. the app won't take the password because of the text_Change() event. how can i work around this?
# 2 if the ser swipes their card, and answers NO to the first message box
and YES to the second, ( i have to have th second nag msgbox,to be sur the user didn't mess up)the code follows correctly it then goes to a function tha strips the delimitting chars. when it comes back, it doesn't return to the code spot it left off at. it returns to the beginning of the text_Change () Event and re-tests the value in te textbox. but if does retain te value of the textbox, and it flashes the message Wrong messagebox (see below)
here are the order of events with a card swipe.
1 checks te string for chars.
2 asks if user is logging In?
3 if user answers NO and then YES to the next message box
4 goes to replace charaters Function
5 returns to the top of the event
6 tests the txtPassword again ? <--- why?
7 goes to the "message Wrong "
8 returns to where it left off in the code after it left to the function
9 continues to log te user out
the app needs to allow a card swipe and a manual password entered i would like to keep the card swipe automation if possible or do i have to put this into a click Event and forget about te auto card deal?
here is the code from the text_Change()Event
<br />
Private Sub txtPassword_Change()<br />
<br />
'test the input from the user to see if tey swiped their card correctly<br />
If Left(txtPassword, 1) = ";" And Right(txtPassword, 1) = "?" Then<br />
<br />
Dim cardID As String<br />
Dim X As Integer<br />
' x is te user response to the message box<br />
X = MsgBox("Are you logging In ?", vbYesNo) Question 1<br />
<br />
If X = 6 Then<br />
Load frmCardLogIn<br />
cardID = txtPassword.Text<br />

<br />
Else<br />
'If X = 7 Then<br />
Dim Y As Integer ' y is the answer to the message question<br />
Y = MsgBox("Are you sure your logging Out?", vbYesNo)Question 2<br />
If Y = 6 Then<br />
txtPassword = ReplaceCharacters(txtPassword, txtUnwanted.Text, txtRepl.Text)<br />
Dim SearchSQlPassID As Integer<br />
SearchSQlPassID = txtPassword<br />

Hi,
I have developed one application using Vb6.0. The application will use my custom dlls. I made installation package using Microsoft Package and deployment wizard, it was running perfectly. If the client wants some changes then i will do modifications on the custom dlls and compile the dlls. one moretime i will make the installation package with the revised dlls. Like this i made lot of versions on my application.
Now i installed .net, i made slight modifications just commented a message box on the dll code and compiled. I verified with the application without making package, it run perfectly. I made package, and run on the same machine, Now i am getting the Runtime error 430, whenever my application is try to run functions on the dll.
I refered the MSDN, they given the solution to unregister the dll and register manually. I did but then also i am getting the same error.
Then I upgraded by latest MDAC_TYP.EXE, then also i am getting the same error.
Please help me to comeout of this problem.

Hi,
Thanks for sending the reply. I referred "PRB: Runtime Error 430 in Client After Server Type is Changed" and unregistered the dll from system directory and the dll from compiled directory. I compiled the dll one more time,Then in the development time the dll is functioning perfectly with the application. If i made a package and installing on the same pc,i am getting the same Runtime error 430. I tried by including MDAC_TYP.exe version 2.0 with the installation package, then i changed to version 2.5 still the problem was there, then i upgraded MDAC_TYP. EXE to 2.8 still the problem exists.
Please suggest to solve this problem.

Do they have the same version of the .NET Framework installed? If not, it won't run...

Does the computer of your friend have the .Net Framework install?? If Yes, then check the version of .Net framework. If NO, then install the .net framework that match with your computer too.

Hello,
Whenever I start up my Pocket PC emulator, it says that it is installing the .Net Compact Framework 1.0, however, it does not install the framework every time I go to debug my application.
In other words, if it is my emulator's first boot, it installs the framework.
I hope this helps

Hello,
I am having troubles allowing only certain keys to work in Visual Basic .Net 2003, using the .Net Compact Framework.
My current code is (on the KeyPress event of a TextBox):
If e.KeyChar = ChrW(110) Then 'Decimal Key
e.Handled = True
ElseIf e.KeyChar = ChrW(46) Then 'Delete Key
e.Handled = True
ElseIf e.KeyChar = ChrW(8) Then 'Backspace Key
e.Handled = True
ElseIf IsNumeric(e.KeyChar) = False Then 'Number Keys
e.Handled = True
End If
However, only the Delete and Number keys work. The keys that I do want to work are the number keys, delete, backspace, and the decimal key.
If anyone could help, it would be greatly appreciated.
Thanks

I have two questions about the print preview dialog.
(1) The MSDN talks about a "zoom" property for the print preview control. I am unable to select find or select that property?
(2) I am wanting to call printer dialog box to select a printer from the print preview dialog when the print button is hit.
Any help with either of the questions above is much appreciated.
Thank you,
Chris
