My app CreateRemoteThread in other apps.
In the remote thread proc, call to GetWindowText fails,
but SetWindowText works.
What's the problem?

According to MSDN, GetWindowText is not able to get window text of other process.

I call it in the thread, and the thread is created in that process using CreateRemoteThread
|
|
|
|
|
In MSDN description:
CreateRemoteThread creates a thread runs in the virtual address space of another process.

Yes, so GetWindowText runs in another process (A) too, What I do is to get the text of window in A. But it still fails.
|
|
|
|

I suggest you to implement a user message handler in process A. And B sends the user message to A. Let A's message handler to do the job to get window text.

Have you tried sending a WM_GETTEXT message instead?

Hi All,
I've the following requirement.
I've an SDI application and an ActiveX component.I need to load the activeX component in the view of the SDI application. That is, host the ocx in a view. The ocx component GUI looks like a dialog having certain controls.When I open a view in the SDI application, I should be seeing the dialog which is nothing but the ocx.
How do i develop the ocx component. Should this be a dialog? how do I host the ocx in the view.?
Please help me.
Thanks in advance,
Yeskay

Why do you need to create and host an ActiveX resembling a Dialog when you can simply use directly a Dialog to the purpose?

The ocx is common component which will have many functionalities. this can be used by many applications. so, creating the dialog and handling it in all the applications is not acceptable.

If you haven't yet developed you ActiveX (taht was my impression when I read your OP) then you have the chance to separate off the "many functionalities" from the UI and go on with a simpler design. On the other hand, if you've already developed it then use MFC support for ActiveX controls.

I'm not very good in ActiveX implementation. So, I dont know what MFC supports for activeX. I just wanted tyo know if anyone had tried such funtionality that I've asked.
I've seen some activeX controls getting loaded in the view, but i cannot understand how.
Anyway, thanks for the replies.

Well, I made a little test (using the standard ActiveX Calendar Control) and it is not such a difficult task. I made the following steps (VS2005):
(1) Create an MFC SDI project (support for ActiveX controls is enabled by default)
(2) Select Project->Add Class menu item and then choose (in the appeared dialog) MFC->MFC Class From ActiveX Control, finally click Add button.
(3) Select Calendar Control in the list of available Active X Controls (in the newly shown window), then select needed interfaces (Calendar Control has only one available), finally click finish button.
Now the class wizard creates a class wrapping the ActiveX Control, and you can use such class. Hence, in the view source code:
(4) Include the created class (for me was CCalendar) header (again it was Calendar.h)
(5) Add a member variable to hold an instance of the class (I used CCalendar * m_pCalendar;)
(6) Override CView::OnInitialUpdate method and inside it create an instance of the class and the call its Create method, for instance, I made
m_pCalendar = new CCalendar();
RECT rc;
GetClientRect(&rc);
m_pCalendar->Create(_T("Calendar"), WS_VISIBLE, rc, this,100);
(7) Enjoy the calendar control (and don't forget cleanup)
I'm sure you're able to adapt the above scenario to your needs, but
please note this was a quick experimental attempt, maybe there are better ways to accomplish the task.

Thanks for the help.
But, how the ocx should be created? Is there any design aspect to be taken care? Because, for some ocx, we can see only the ellipse/circle when we do like above. We are not getting the ocx component with all its functionality.
May be this is a stupid question...But, I dont understand how the ocx's are created to get show the component when we host in view.

Does your ActiveX work? I mean, if you put it, for instance, inside a very simple VB6 container, do you see all the GUI magic?

I'm able to implement as per my requirement(with controls in the dialog).
Thanks a lot for your comments

Maybe he wants to make something like the ActiveX Control Test Container tool of VC++.

Hi,
It is somthing like that.
But, it should show the dialog with all controls working instead of the ocx icon.
Thanks for the response.

I know very little about ActiveX things. But maybe you can refer to the sample code.

Thanks for the link.
I'm able to understand the implementation. But, how do I create my OCX?
When I use my OCX or some other built in components, I'm able to see only the ocx icon (ellipse or circle) unlike calendar/DBGrid etc.

Hi all.
I need to emplement some problem, that its part is constantly running, for example, 20 threads.
I use the followong code:
<br />
<br />
<br />
<br />
#include <windows.h><br />
#include <stdio.h><br />
<br />
int counter = 0;<br />
int released = 0;<br />
int limit;<br />
<br />
int maxNumberOfThreads = 20;<br />
HANDLE threadCreator;<br />
HANDLE threadHandle;<br />
DWORD threadID;<br />
void Release()<br />
{<br />
CloseHandle(threadHandle);<br />
CloseHandle(threadCreator);<br />
}<br />
<br />
void Initilize()<br />
{<br />
limit = 0;<br />
threadCreator = CreateSemaphore(NULL, 0, 50, NULL);<br />
if(threadCreator)<br />
{<br />
Release();<br />
}<br />
}<br />
<br />
<br />
DWORD WINAPI Start( LPVOID lpParam )<br />
{<br />
WaitForSingleObject(threadCreator, INFINITE);<br />
printf("ID = %d\n", GetCurrentThreadId());<br />
--limit;<br />
++released;<br />
ReleaseSemaphore(threadCreator, 1, NULL);<br />
return TRUE;<br />
}<br />
<br />
void StartSimulation()<br />
{<br />
while(true)<br />
{<br />
if(limit < maxNumberOfThreads)<br />
{<br />
threadHandle = CreateThread(NULL, 0, Start, NULL, 0, &threadID); <br />
if(!threadHandle)<br />
{<br />
Release();<br />
}<br />
++limit;<br />
++counter;<br />
}<br />
if (counter == 100) break;<br />
}<br />
WaitForSingleObject(threadHandle, INFINITE);<br />
printf("Created %d threads.\nRelease %d threads.\n", counter, released);<br />
}<br />
int main()<br />
{<br />
Initilize();<br />
StartSimulation();<br />
Release();<br />
return 0;<br />
}
I understand that there is something wrong. Any ideas how to fix it and to make this work?
Thanks in advance.
