hi!
I wish, in my program to send Message via
"SendMessage" to the "NotePad".
For a start, I want to send a WM_KEYDOWN
to write a letter in notePad's writable area.
I have the handle of the notePad.
if any one can assist me, I would be very
very thankful.

Try it.
You will probably have to send a WM_CHAR as well.

Thank you for your help.
what I really need to do is:
I need to, from without the note pad, close a modal messageBox.
modal - messageBox is reffered to the messagebox you get once you try to exit the notepad and you're asked if you wanna save the changes .
this msgbox I need to eliminate , I assume, with a message from an outer application.
If anyone has an idea or has done such a thing before - I would be glad/relieved to know - for this is part of a very urgent assinment I have to accomplish.
Thank you (again) ,Eynat

Yes, you can use this trick to do that.
You'll find 2 windows in notepad - the main frame window (whose handle you can FindWindow based on the caption - e.g. "Untitled - Notepad") - and its child, which is an edit box.
To type text into notepad, post the key stuff to the edit box.
To send a key that will close the messagebox (Y, N, ESC), send it to the main window.

Anyone knows how to deal with ghost windows in XP? How to get rid of the ghost windows in windows XP system with Platform SDK? Thanks.
Windows XP: If a top-level window stops responding to messages for more than several seconds, the system considers the window to be hung and replaces it with a ghost window that has the same Z order, location, size, and visual attributes. This allows the user to move it, resize it, or even close the application. However, these are the only actions available because the application is actually hung. When in the debugger mode, the system does not generate a ghost window.

I'm using the following code to open a URL in the user's browser:
CString strUrl = "http://www.codeproject.com";
if ((int) ::ShellExecute (m_hWnd, "open", strUrl, "", "", SW_SHOW ) <= 32) {
...
}
This causes the same (I suspect the most recently opened) IE window to display the site. Does anyone know how I can force the system to open a new instance of the browser each time the code executes?
Thanks muchly!

For the verb, try running IE explicitly.
::ShellExecute(m_hWnd, "open", "iexplore http://www.codeproject.com/", "", "", SW_SHOW)
There might be another way also, and of course this would only work if IE is included in the path, so you may want to check the registry for validating this beforehand.

related-- (if you are invoking IE explicitly
using ShellExecute)
IE has some command line options
see MS KB article Q178058
try the -new option
but as long as you are limiting to IE,
go all out and use the exposed automation...
|

|
|
Use "-new" command line option.

Do you know how could i use the equivalent of C's escape sequences in VB to write strings like this: "a1 \"b1\" c1"?

Shame on you for cross posting! I'll answer this in the VB forum.

Mmmhh ... In a dialog MFC app, I have a thread MainThread in which i start a thread ChildThread. The ChildThread has a priority set to LOWEST, and the MainThread set to ABOVE_NORMAL. However, when I debug step by step, the ChildThread seems to run with a greater priority than the MainThread(100/1 instructions ratio). Why ?

How have you determined this ratio? Please note that it is higly unlikely you're calculating any significative figure within a steyp by step debugging process. Also, the number of instructions per second executed by a thread does not only depend on its priority, but also on the frequency of yielding operations it performs (ops for which the system deems it appropriate to pass the control to another thread till they complete, such as IO APIs.)

I determined the ratio this way : I have two 'for' loops in the Child threads, doing some stuff. So when I launch the ChildThread from within the Main, it starts and finishes the first loop in the CT, does one instruction in the MT, does the second loop in the CT, and return for one instruction in the MT. Since the 'for' limit is 102 in both 'for' loops, I had my ratio

That´s exactly what i wanted to know when posting my thread. I thank you very much ...

Probably a misimpression caused by debugger. How are you measuring this performance difference? Is the problem that the main thread is sitting in single step mode while the child is executing?
Also, be aware, setting priority is not the same as setting speed. It simply means that when given a choice between the 2 threads waiting for the same resource, the higher priority thread will go first (within limits).

According to the MSDN On-line, the "Programmer's Reference" installs, by default, a command-line utility called Bitmap.exe as part of ICM 2.0; I am in need of that utility. I've been unable to determine from where this program is installed (i.e., Platform SDK, DDK, Etc...) but I do know that I do not have it on my machine and the MSDN On-line does not indicate where this program can be downloaded from. 
Any ideas from what CD I can get this? 
Here's the link to the MSDN page that references this program
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/icm/icm_16pc.asp
TIA,
D.

It is included in the Platform SDK.
On my pc it is in the "Platform SDK install Folder\bin" folder...

Thanks for the response. Shortly after having posted this message, we discovered it as well on the Platform SDK CD.
Unfortunately, it does not resolve our issue, even if it's a really cool utility.
Thanks again,

Hi guys, whenever I place the following code into a module within my project, I get a linker error
(error LNK2001: unresolved external symbol _cmc_logon@36)
The offending piece of code is...
::cmc_logon(NULL,NULL,NULL,NULL,0,CMC_VERSION,NULL,&Session,NULL);
where I have set Session as CMC_Session Session.
I've already included xcmc.h into my project, any ideas on why I'm still getting a linker error?

is there any .lib files missed in Linker options?

Hi everybody,
Q1a: Why does a dialog based MFC app take appr. 1200KB of working memory?!
Q1b: I created an exact copy of this MFC dialog app with Delphi with the exact same functionality and it only aquires 150 KB of RAM... How come Delphi (Pascal) outperforms the living sh*t out of a regular C++ app?
Q2: Within my MFC app I wish to allocate an array of let's say 1 000 000 Things where Things defined as
class Things
{
int m_nType;
int m_n123[3];
}
I do it like this
ptr_things = new Things[1000000];
This, as far as I've understood it, allocates memory this way:
1000000 * (4 bytes + (3 * 4 bytes)) having integers with 4 bytes, correct?
Now, I can see in the task manager (w2k) that the memory used by the app increases violently when this line of code is executed.
BUT, when doing exactly the same thing (not quite, i statically declare a 1000000 array) in Delphi the memory increases only by a few hundred kilobytes.
Can anyone explain this to me please? Feels weird to develop with C++ when Delphi seems to rock the world! Is there another way to allocate more efficiently?
Q3: If I have a lengthy process where I do something like this...
int nSomeStuffCounter = 0;
int nNumberOfLoops = 243;
CString str;
for (int a = 0; a < 3; a++)
for (int b = 0; b < 3; b++)
for (int c = 0; c < 3; c++)
for (int d = 0; d < 3; d++)
for (int e = 0; e < 3; e++)
{
DoSomeStuff();
nSomeStuffCounter++;
str.Format("%d%% done", (int)(((double)nSomeCounter/nNumberOfLoops)*100));
wndStatusText.SetWindowText(str);
}
... it takes very (!) long time for the process to finish where as I remove the status reporing it works quickly. Trivial enough... BUT how can I report the progress of a lengthy process without slowing the process itself down too much? And I don't wanna hear progress bars... they kill the performance of any app. Or am I wrong? Can threading help me here...?
Thx for any advice,
/Tommy

A1a: MFC is a class library which resides in DLLs. Windows will load these DLLs when you run your app.
A1b: I don't know jack about Delphi, but its probably built on top of the WinAPI. MFC apps add a layer in between you and the API. As far as out performing the living sh*t out of a regular c++ app, I would have to see the performance stats to believe it. Try writing a windows app with the API in c++ and see which one wins.

I don't believe this for a second. Besides, a class is different than an array so I wouldn't expect it to be the same. I just doubt that Delphi only allocates a few hundred kb.

A3: If you want to report the progress, you're going to have to sacrifice a little speed. GDI is not the fastest thing in the world so updating text or a progress bar using GDI is going to suck some speed out. Threading will help, but it will still be slower than having no updates at all.

This is a c++/mfc forum, I suggest you take the "Delphi kicks MFC a$$" attitude elsewhere.
