ok i accept,
then is there any way to get the fun name and parameter set in a generic way before i access the function from my program , and this all should happen dynamically
|
|

Yes and no. There's a way, how to get the name of the functions, but problem is with parameter set. The best you can get without disassembling is a number of bytes that should be transferred to the function.
If you look at the SDK tool called depends.exe, you'll see what can you get.
If this is enough for you, you can look at the ImageHlp library as described in MSDN. This will help you to parse the info stored inside the dll (which is PE executable)

In addition to the above response, you can also use the DumpBin.exe utility to see all publicly exported functions available to you.
The parameters needed and usage will still be needed in advanced though.

Hey,
A sort question really. How do I get text from one of the lines in a listbox?
I thought I could do something like this:
SendMessage(listbox1, LB_GETTEXT, 1, 0);
But how should I then use a buffer to save the text?

From the MSDN doc:
LB_GETTEXT
wParam = (WPARAM) index;
lParam = (LPARAM) (LPCTSTR) lpszBuffer; Parameters:
index
Value of wParam. Specifies the zero-based index of the string to retrieve.
lpszBuffer
Value of lParam. Pointer to the buffer that will receive the string. The buffer must have sufficient space for the string and a terminating null character. An LB_GETTEXTLEN message can be sent before the LB_GETTEXT message to retrieve the length, in characters, of the string.

As Ravi said.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif) Here is a small example:
int
GetListboxSel( HWND hCtrl_Source, char* szItem, const int nItemLen )
{
const int nIndex = (int)::SendMessage( hCtrl_Source, LB_GETCURSEL, 0, 0L );
if ( nIndex != -1 )
{
const int nLen = (int)::SendMessage( hCtrl_Source, LB_GETTEXTLEN, nIndex, 0L );
if ( nLen < nItemlen )
::SendMessage( hCtrl_Source, LB_GETTEXT, nIndex, (LPARAM)szItem );
else
*szItem = '\0';
}
else
*szItem = '\0';
return nIndex;
}

I'm trying to wrap a pure MFC control into an ActiveX, and use it on an WTL App dialog.
Problem: TAB works spuriosly (it has some functionality within the MFC control's child controls), Return works not at all (the control doesn't see it).
Any ideas?
Here's the deal:
ActiveX Server: ATL DLL with MFC Support
ActiveX control:
ATL Full Control,
the MFC child window is created in OnCreate
Client:
WTL modal dialog based app, Control added to the resource.
Any stuff I need to add/call?
(I tried to add the OnPreTranslateAccelerator and SetFocus that ATL Wizard adds to a full control containing a windows control, but this didn't change anything)

Hi all,
I have a word Add-in from which i will open a word new
document. For this document I want to remove maximize,
resize option. I'm able to remove the resize option using
style &= (~(WS_THICKFRAME));
and applying this style property to the document window using user32.dll
library imported function.
Similarly I tried to remove maximize but its not working.
Any help in this regard is highly appreciated either through C# or
VC++(native).
Thx & Regards

I am displaying a windows form from within a TAPI event handler to display some information about an incoming call. However the forms window is not selectable. When the cursor is moved into that window it just comes up with the busy shape. My guess would be that it does not have any event handler associated with it. Can anybody help with this problem and how to fix it?
|

Create a modeless dialog or other window elsewhere in program.
Have your TAPI handler post messages to this window concerning the TAPI status.
Some window messages are not processed from within a handler, they are only processed the next time through the window's message loop and your TAPI handler is probably not in a regular message loop, as you suspect.

Hi all,
I'm trynig to show the main window of another process and it's driving me crazy!!!!
I get the process handle using
Process* MyProcess[] = Process::GetProcessesByName("EXCEL");
I found the MainWindowHandle property of a process
MyWnd = MyProcess[0]->MainWindowHandle;
But... how to use it. I wasn't able to find any way to make .NET 2003 accept the __int32 (IntPrt) the propery return in any window managing function.
PLEASE HELP ME!!!!

How about:
ShowWindow(MyWnd, SW_RESTORE); I don't use .Net so this is just a guess.

Hi all guru!
I tried to get the file associated icon location by using following code. but shinfo.szDisplayName is empty. Could you please point out the error?
<br />
SHFILEINFO shinfo;<br />
memset(&shinfo,0,sizeof(shinfo));<br />
CString loc; SHGetFileInfo("c:\\po.txt",FILE_ATTRIBUTE_NORMAL, &shinfo, sizeof(shinfo), SHGFI_ICON|SHGFI_SMALLICON|SHGFI_ICONLOCATION);<br />
loc.Format("%s",shinfo.szDisplayName);<br />
DeleteObject(shinfo.hIcon);<br />
Thanks

The icon index is in iIcon not szDisplayName. If you want to retrieve the display name, you need to add SHGFI_DISPLAYNAME to the flags mask.

Looks like you got everything handled.
Does the file actually exist?
Maybe you did not include this part...
You must initialize Component Object Model (COM) with CoInitialize or OleInitialize prior to calling SHGetFileInfo.

Hi All,
To create a new desktop we use CreateDesktop which returns the handle of the newly created desktop. Now when the work is done how do I destroy this desktop. CloseDesktop function just closes the handle but does not destory it. Any other API?

Why are you differentiating between "close" and "destroy?" When CloseDesktop() is called, the handle is closed. What's to destroy?

CloseDesktop() is compitible with OpenDesktop(). If one has used OpenDesktop() which retrives the handle to an existing desktop then he/she has to use CloseDesktop() to close the handle but it does not destroy the desktop which was already existing before. In my case I am creating a new desktop using CreateDesktop(). I want to destory the desktop after my work is done. CloseDesktop() is not sufficient here.

In MSDN documentation of CreateDesktop, it is said that after you're done with the desktop handle, call CloseDesktop to close the handle.
You don't need to explicitly destroy the created desktop. Instead, when you close a desktop handle, if there are no more open handles to the desktop, the object is automatically destroyed. You can think it as a COM object. First you call CreateInstance, use the object, then call Release. If no more references to the COM object exist, the subsystem destroys the object and frees the memory. The same happens with desktop objects.
This is the way it is designed to work, because explicitly calling 'DestroyDesktop' on a desktop object (such as the main Windows desktop) which is still in use can have highly devastating results. That is the reason why the destuction of desktop objects is left to the subsystem, and you can only open and close handles to the desktop. Call it a security feature, or just the prevention of malicious use, if you like.

Is this a .Net-related error?

Do you mean the function is exported outside any namespace and then tried to import inside a namespace? If so, I guess you're out of luck, namespace location has to coincide. Think of the namespace(s) a function is located into as part of its "name". A workaround could be the following:
declspec(dllimport) void foo();
namespace A
{
using foo;
}
