With ASP the following script on your website should do the trick.

<% @ Language="VBScript" %>
<% Option Explicit %>

<title>Start an exe-file with ASP script

<%
dim wsh
set wsh = Server.CreateObject("wscript.shell")
wsh.Run("C:\Windows\Notepad.exe")
set wsh = nothing
%>

ASP does only work with the Internet Information Server from MS (as far as I know). If you use another webserver you need another (server side) scripting language (PHP for example)
Furthermore you need to set the file-permissions for access through the webserver in the correct way.
Search Google for "ASP Tutorial" and you will find a lot.

What do you mean by use it ? Could you be more precise ? Do you want to reuse the sources files and compile them in visual C++ ? Or do you want just to run the program executable ?

If this is the first option, it depends of the sources files themselves. I don't know PowerBuilder at all so I don't know if it uses some libraries of its own. If this is just plain C/C++ files that doesn't make any call to specific API or libraries from Power Builder, then there should be no problem to compile them.

If this is the second option, you can use ShellExecute.

Ok ! You could have say it was a dll Laugh | :laugh:

. That changes a lot of things. There are two options to use the dll: either implicit loading of the dll or explicit loading.

For implicit, you will require the header file which contains the prototypes of the exported functions. Then, you add this file to your project and you add the dll in the project (I don't remember exactly where in the project settings, you'll have to look a little bit for that).

For explicit, what you will make direct call to the API through functions like LoadLibrary (to load the dll) and GetProcAdress (to retrieve the adresses of the functions you would like to call). Take a look in the MSDN for more documentation (it is a little bit long to explain in details here).

Hope this helps

Sounds like you should use a CListCtrl. It allows you to insert items with checkboxes and has a scrollbar too.

Hello all,

When use callback function, and what is the purpose?
Which cases we should use the callback functions?
Could you tell me about?

Thanks!

Callbacks are typically used when the function needs to notify its caller for some reason. This can be for simply informing the caller or for getting information necessary for the function to continue execution.

For example, you can have a timer function that runs in a loop and needs to notify someone whenever a timer expires. You'd write something like

void TimerFunc(CallbackFunc *func)
{
   while (1)
   {
       // Wait for specified time
       ...
       func();
   }
}

They can also be used to alter the function's flow depending on the caller. For example

void SomeFunc(CallbackFunc* func)
{
  int x = ...; // Some runtime parameter
  if (func(x) == true)
  {
     // Do this
  }
}

As you can see, func gets the ability to change SomeFunc's control flow.

why doesn't TRACE output correctly?

liuyue30-Jun-05 22:47

CString strTemp
strTemp.Format("%-60s%-20.1f\r\n%-60s%-20.1f\r\n%-60s%-20.1f\r\n","Global Wall",0,"Limiting Potential",0,"Roughness Correlation",0);
TRACE("output:%s\n",strTemp);

when debugging, the output is:
output:Global Wall 0.0
(null) 0.0
? -2.0

how can i dispose of the problem?

Try casting your 0 to (float) 0
Now, they are int's.

// important to case the CString since the TRACE does not know argument type
TRACE("output:%s\r\n",(LPCTSTR)strTemp);

All you need to do is replace each 0 with 0.0 instead. When Format() encountered the %f, it attempted to pop a float type from the stack but got an int type instead.

help to solve this

Looks like you are trying out the ADO tutorial in MSDN. The variables adVarChar etc.. are in msado15.dll. Did you import the "c:\Program Files\Common Files\System\ADO\msado15.dll" into your program?

Just right click the file in Solution Explorer and click 'Properties'.

You can't make the file compile with the Release settings while the project compiles as Debug. But you can make the file properties for the Debug configuration match those in the Release one.

Hope that helps,

UpdateDriverForPLugAndPlayDevices fails to upgrade the printer driver dll (language monitor) to the latest version provided (even with INSTALLFLAG_FORCE option.)
Can any one tell the reason for the this?
More Info : The driver I was trying to upgrade had the same driver version as already installed driver, but one of the dll was changed, which I needed to upgrade. I had the proper signed cat file for the changed dll.

Hi Is there any restrictions on the packet size that the server can send to client?
Because when my server sends data of the size 5KB to client after some time a run time error is generated at my client side.

But when i change the data size to 2KB, run time error is not generated.

Why so?

Waiting for suggestions.
