I am trying to add WTL support to the WinAPI DLL project.
I was write in the stdafx.h:
#include <windows.h>
// C RunTime Header Files
#include <stdlib.h>
#include <malloc.h>
#include <memory.h>
#include <tchar.h>
#include <atlbase.h>
#include <atlapp.h>
extern CAppModule _Module;
#include <atlwin.h>
#include <atlgdi.h>
#include <atlmisc.h>
Compiler messages was:
c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\WinSock2.h(1149) : warning C4005: 'BIGENDIAN' : macro redefinition
c:\MyProjects\TQPS\402Headers_Libs\Win\XTPLAT40.H(148) : see previous definition of 'BIGENDIAN'
c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\atlmfc\include\atlcore.h(246) : warning C4002: too many actual parameters for macro 'LoadResource'
c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\atlmfc\include\atlcore.h(246) : error C2589: '(' : illegal token on right side of '::'
c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\atlmfc\include\atlcore.h(246) : error C2059: syntax error : '::'
c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\MsXml.h(1932) : error C2059: syntax error : '('
c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\MsXml.h(1933) : error C2238: unexpected token(s) preceding ';'
c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\PropIdl.h(915) : warning C4002: too many actual parameters for macro 'Create'
and so on... There was 75 errors. That is the problem? The same includes in a blank WinAPI project are working well.
Could anyone help me?

Hello dandy_andy!
You have make like this:
CAppModule _Module;
BOOL APIENTRY DllMain( HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
{
HRESULT hRes = ::CoInitialize(NULL);
ATLASSERT(SUCCEEDED(hRes));
hRes = _Module.Init(NULL, (HINSTANCE)hModule);
ATLASSERT(SUCCEEDED(hRes));
}
break;
case DLL_PROCESS_DETACH:
{
_Module.Term();
::CoUninitialize();
}
break;
}
return TRUE;
}

Hi,
I'm pretty new in programming in c++.net, and I was wondering if someone could help me out.
The goal is to control Abobe Acrobat so that it displays a pdf file in my own c++.NET application. I have found an example in the Acrobat SDK called ActiveView which is exactly what I want to achieve, but I have really no idea how it works.
Can anybody give me an explination of how it works, or how to make a start?
thanx!

Hi,
I developing a component using ATL. This component is suppose to generate events. The wizard generated the Proxy Class implementation of Events (CProxy_xxx).
I am trying to Fire an event using this class implementation.
But I am recieving 0x8002802B ( -2147319765 ) TYPE_E_ELEMENTNOTFOUND error.
I am passing two parameters which are of type IDispatch*
The client used is VBScript.
Does someone here has any idea about what possibly would have gone wrong?
Thanks for looking into this.

hi there,
im using ado in vc++ for access db
i have used this query but it shows
"data type mismatch in critria expressing"
SELECT * from FDetails where ddate = '05/29/2006'
ddate is datetime field
any one has solution for this problem
regards,
Gan

Maybe
SELECT * from FDetails where ddate = "05/29/2006"
or
SELECT * from FDetails where ddate = #05/29/2006#
I believe this is not a post for the ATL/WTL/STL group...

HI
ya its working.
I had not got any response from ADO GROUP hence i posted here
thank you
|
|
|
|

Something like this:
SELECT * from FDetails where to_char(ddate, 'mm/dd/yyyy') = '05/29/2006'

 Hi
Gan,You have not any mistake in the query, But problem may there if your format in oracle registry is different.check the registri.
For urjent you can find by using like statement for date field.
Thanks

Hi,
I have an Window which has Edit Controls.
How do I change the font for an edit Control?
I am unable to trap the Backspace key for the Edit Control. When ever I press Backspace on the Edit Control, the backspace is caught by the parent window. Can anyone tell me why?

On setting the font: look up the WM_SETFONT message. You don't mention what libraries you're using but some libraries will have wrapper functions which send this message for you.

Hi.
Thanks for your reply. It is indeed the WM_SETFONT message. I am using WTL 7.0 so I could do it with SetFont().
One queston which I would like to ask is, How do I change the Height of an Edit Control? Well, I am using SetWindowPos, but the height is not being set accoring to what I give the SetWindowPos function. Does the Edit Control have any other means by which its height can be changed? Also you may be thinking that the height of the control will not be smaller than the height of the font. Let me assure you that I have changed the height of the font using the SetFont() method.
Any suggestions?

SetWindowPos should work just fine. e.g.
::SetWindowPos(hWnd, NULL, 0, 0, 100, 100, SWP_NOZORDER|SWP_NOMOVE);

Hi Stephen.

Well, SetWindowPos is not doing the Trick. That's why I asked!

Did you:
1. Pass the correct window handle. To check you can do something like call GetWindowText with the HWND and make sure its the correct control; or you could use Spy++.
2. Did you pass the correct flags to SetWindowPos?
Steve

Hey Stephen,
I am sure you aren't gonna believe this but I have been a #$%^#$ Ass  . I wasted one whole day trying to figure out why SetWindowPos is not working and I found the culprit. The culprit is ME. Instead of passing the Height and Width to the SetWindowPos function I was actually passing the position for the right and bottom corners of the control relative to the Left and top positions.
It was something like, if the top of the control is 20 then to get a height of 20, I was passing Top+20 to the Height argument. How silly of me.
Anyways, thanks a lot for your support. I really appreciate it.
Thanks once again.

I want to apply HTML hooking from my ATL project.
I seen articles from MFC examples,
i don't know how to use them in ATL.
If someone has idea then please reply.

What do you mean by "HTML hooking"?

This is probably a dumb question, but I will ask it anyway:->
In my app I am running two threads, the main GUI thread and a data gathering thread. In the application object I have a std::queue object that I am using for data entry. The gathering thread pushes objects into the queue and the the main GUI thread reads and pops the same objects off the queue. My question is do I have to synchronise access to the queue using a critical section or is it perfectly safe to push on one end and pop off the other without worrying about synchronzation? I ask because I want the data gathering thread to be able to run as fast as possible, without having to wait on a critical section while the main thread does it's data accessing.
#define WMU_NEWDATA WM_APP + 0
#typedef std::queue<CMyDataClass> DataQueue;
class CMyApp : public CWinApp
{
...
DataQueue InputQueue;
...
};
extern CMyApp theApp
...
CMyDataClass InputData;
...
...
theApp.InputQueue.push(InputData);
theApp.m_pMainWnd->PostMessage(WMU_NEWDATA, 0, 0);
...
LRESULT CMainFrame::OnNewData(WPARAM, LPARAM)
{
while (!theApp.InputQueue.empty())
{
CMyDataClass NewData = theApp.InputQueue.front();
theApp.InputQueue.pop();
}
}
You may be right
I may be crazy

Never mind, I tried it and gave my app a good rush of data and it crashed and burned. The critical section seems to be a necessity after all.

If the data item's small enough, can you pass it in the LPARAM/WPARAM of the message? Or, alternatively, new it in the data gathering thread and use/delete in the GUI thread.
Not using shared state is always the best way of doing concurrency - message passing, a la Erlang, is much less likely to break horribly

The only problem I have with passing messages is the size of the message queue. On windows 2000/XP it is limited to 10000 messages. Not that it is likely to happen often, but if that limit gets hit then I would start to run into other problems such as memory leaks and lost data. By using a custom queue I hope to avoid those problems.

Yeah, I'd have to agree about filling up a message queue - I've managed it when using a worker thread to update UI (a ProgressBar, using PostMessage) directly - had to reduce the update rate.
You're probably OK using critical sections anyway, so long as you're not sampling too quickly - I've got code that samples at something around 1ms (and does lot's of other stuff as well) that works perfectly OK. Just make sure you haven't got hard real-time requirements, 'cause Windows can't do that reliably.
