This has the advantage when you plan to have multiple language versions of your product.

I do that when work with diferent languages.
I put the resource into dlls, and share it from the dll....

Radio buttons not playing fair

I'm sure this is a basic interface mistake, but if anyone could shed some light on it I'd be very grateful.

I've got an existing dialog with 5 radio buttons on it, I need to put on a sixth radio button, but when I do I can have the new one selected with one of the others selected (instead of only one as intended). Can anyone let me know how to get this new radio button to be part of the group that the others are in?

TIA

You need to go into the .rc file and make sure this radio button is defined in the same group as the others, i.e. move it's defintion before any other controls that have also been added since the radio buttons where added.

You don't have to edit .rc file manually - just use Ctrl+D to change the tab order.

Does that work ? Changing the tab order will move the radio buttons into a group ? Does changing the tab order change the rc file ?

Wait for external App closing

12-Mar-02 2:14

Yes, it works. Radio buttons have to be in one group. First of them must have WS_GROUP bit set. One group ends where another begins, so first control *after* radio buttons must also have WS_GROUP set.

If you add new radio button and set its tab order, everything will work OK.

Absolutely - 'tab order' is actually the order of control statements in .rc.

Hi there. How i can do this ? My app call another app by ShellExecute. I'm need inform user by msg window if external app end work

Tomasz Sowinski12-Mar-02 0:36

1) Use ShellExecuteEx to get the process handle
2) start the worker thread in your process. The thread will immediately call WaitForSingleObject passing the process handle received from ShellExecuteEx
3) when thread exits from WaitForSingleObject, the external app finished work. PostMessage to the main thread and exit from worker.

Hey it's a great idea to start WaitForSingleObject() in a different thread.

But how do I send a PostMessage() to the main thread and which parameters do I need to send?

#define WM_EXTERNAL_PROCESS_FINISHED (WM_USER + 1)
// ...
// from the worker thread, just before exiting
pMainWnd->PostMessage(WM_EXTERNAL_PROCESS_FINISHED);

Read this article. It gives a sample code snippet on what you want to do.

Que:- ATL equivalent for the MFC CArray class

User 665812-Mar-02 0:41

Use ShellExecuteEx() instead.

SHELLEXECUTEINFO sei = {0};

sei.cbSize = sizeof(sei);
sei.lpVerb = "open";
sei.lpFile = "yourapp.exe";
sei.nShow = SW_SHOWNORMAL;
sei.fMask = SEE_MASK_NOCLOSEPROCESS;

ShellExecuteEx(&sei);
	
WaitForSingleObject(sei.hProcess,INFINITE);

WaitForSingleObject will return when the other app has quit

I would like to know whether there is an ATL equivalent for the MFC CArray class. Assuming I do not want to use STL. Basically one reason for using ATL is to avoid bloated libraries (even if only slightly bloated) like MFC and STL.

I don't believe your code will bloat significantly if you use only std::vector.

There's a CSimpleArray in ATL, but AFAIR it's designed to be an internal class.

Thanks Tomasz. Lemme add here that I am not very comfortable with STL. I am not smart enough to use it. Frown | :-(

That's why I need to depend on simpler solutions.

You don't need to be smart Smile | :)

To use std::vector you don't even need to know about iterators and other fancy stuff. Just do the following:

1) include <vector>
2) instantiate a variable:

std::vector<int> v;

3) set the size

v.resize(100);

4) load elements

for (int i = 0; i < v.size(); i ++) v[i] = i;

5) load even more

v.push_back(999);
v.push_back(888);

6) access the elements

int x = v[33];

Thanks Tomasz. I'd like to avoid this step. I dont want to set a start size. I want to create an array and keep inserting stuff into it. Then after I am finished I simply return the array Smile | :)

Is that possible?
I am too tired now to look up MSDN to find out whether push_back does this for me. It probably does.
