Hey,
I have a dialog appear while a thread is running.
But on this dialog i want to place a cancel button that cancels the thread when it is clicked.
Is there anyway that VB.Net knows which threads are running in the app so it can kill them?
Thanks for your help, this is really important

I need to create one application("New.exe"):
with this event on Form1_Load:
hIr = FindWindow("Ir", vbNullString)
If IsWindow(hIr) = 0 Then
Call Shell("Ir.exe", 1)
Do Until IsWindow(hIr)
hIr = FindWindow("Ir", vbNullString)
DoEvents
Loop
It opens another application("IR.exe"), but I need to press one button of IR.exe, it reads three textboxes and it prints the values in my new application. But in hide mode!! It's possible ??

If it's hidden, no. This is because in order to receive input, like clicking on buttons, the app, and the target control, has to have the focus. In order to have the focus, the form must be visible.
If the app has shortcut keys (ALT-something) assigned to the buttons, then you can just use SendKeys to send the appropriate keystrokes that do the same thing as clicking the button. If not, it's MUCH more difficult, because now you have to know the coordinates of the button within the form and use the Win32 API function SendInput to send formatted mouse button messages to the target window.
Reading the text boxes will also not be easy. You must get the window handle of the textbox, send it the appropriate window message, I think it's WM_GETTEXT, and a pointer to a data structure that the textbox can write it's information to.

Hi All,
Can U Tell me the Difference between DHTML and Web controls in VB6. I m waiting for your kind consideration. Thanx
|
|
|
|
|
What is DHTML?[^]
Web Controls are custom controls, written in VB6, that generate HTML.

Hi, I have a form in vb.net that use to search value in the database (msaccess) based on the user input. The result is display on the list view. The form that I connect to database is done by code, not by wizard. And I also design a report in crystal report. The result that search by the user will display in the report. My question is: how could I get value in the list view to display in (crystal) report? Or how could I display the value in the list in the simple HTML file?
A thousand mile of journey, begin with the first step.

I'd like to learn how to build some simple applications. I'm just starting out, I shouold be doing this in classes next year but i'd love a head start. I hear this is all about math, and i'm not the best math student. Please, i have the program on my machine at home already, just help me, please. Thanks in advance.

Welcome to the coding community, simiyah.
First of all, you need to think about what you want your computer program to do... what task is hard for you to do yourself, and you want your computer to do it for you. For example, would it be fine to have a program that would autmatically solve algebraic phrases, so when you are doing your math homework, you don't have to? (I know you could use software that you already may have for this, but the point is doing it yourself!). Do you want a 'more' customizable notepad? Do you want a tetris where pieces could be moved in all directions (even 'up')? Think! the sky's the limit!

Ok, this is how coding works (for me, at least). Think of coding as making a house... I can't give you an already made house, without the appliances, so you just put in a few appliances and that's it! YOU try to make a house, and when you have a problem fixing a window, or turning on and off a light, or setting up a stair case, I'll help you... but I definitly can't make the whole house for you! I suggest you read a few tutorials from the web, a search on google on that subject wouldn't be bad, but I can offer you the tutorial I made myself, to explain the basic concepts of VB programming, you can find it here[^]
Ok, hope you are moving forward with all this thing.

My boss just got a program. An executable file. He wants me to find a way of securing the executable i.e making sure that the program can not be duplicated and used on another system seamlessly. I suggested using activation keys but the problem I have is that someone can still copy the executable file and use it on another system. He doesn't want that. I know that activation keys can be implemented but I think its from within the program not outside. How do I protect an executable file from outside Need help, ASAP. Urgency is an understatement.

Well, search the web for "developer copy protection". You'll come up with all kinds of products that can do this. But 8) Copy protection is a pipe dream.
NONE of these products and schemes are foolproof. ANY copy protection scheme can be broken. Even the ones that require a little dongle attached to a parallel port. The reason for this is because no matter what, every copy protection scheme comes down to a single if statement that can be found and changed to allow the program to run, even if the protection key no longer exists.

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!
Chris

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 />

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.
