Have you tried debug stepping into the DoModal function, this should give you more clues to what the problem. Also the sample code provided will show the dialog twice.
Is the DLL's resource identifier range different to the applications's resource id range?
Michael
Programming is great. First they pay you to introduce bugs into software. Then they pay you to remove them again.

You might have been bitten by MFC dialog creation code that tries to load the resource with the same name or ID from the executable, not from the DLL itself.
You must make your DLL an "MFC extension DLL". How to do this is reasonably well documented in e.g MSDN.

 Where can I find the registry key for the path of the current WebBrowser / EmailReader?
Who can I get/read the icons from these exe-files ?
Please, give me an answer ...

Thank you, but what about the default email reader (outlook / outlook express / ...) ???
Thanks again ...

Hmm.. maybe this !?

Thank you very much for your quickly response, but...
what can you tell me about the fallowing keys ?
1. HKEY_CLASSES_ROOT\mailto\shell\open\command
2. HKEY_CLASSES_ROOT\Microsoft Internet Mail Message\shell\open\command
3. HKEY_CLASSES_ROOT\Microsoft Internet News Message\shell\open\command

hi!
I'm working on a Consumer - producer program. It is required to measure the time that the producer producing, waiting and the consumer consumes and waiting. However i'm having some trouble measuring those. Does anyone have any ideas?
The following is my code that i've written so far:
<br />
#include "buffer.h"<br />
#include <windows.h><br />
#include "screen.h"<br />
HANDLE NFull, NEmpty;<br />
HANDLE mutexProTime, mutexConTime;<br />
int sleepTimePro = 100;
int sleepTimeCon = 200;
<br />
void Buffer::BufInit(void)<br />
{<br />
bufferSize = 8; <br />
NxtIn = 0;<br />
NxtOut = 0;<br />
NFull = CreateSemaphore(NULL, 0, bufferSize, 0);<br />
NEmpty = CreateSemaphore(0, bufferSize, bufferSize, 0);<br />
mutexProTime = CreateMutex(NULL, TRUE, 0);<br />
mutexConTime = CreateMutex(NULL, TRUE, NULL);<br />
proTime = proWaitTime = 0;
conTime= conWaitTime = 0;
<br />
}<br />
void Buffer::BufPut(char c)<br />
{<br />
<br />
if(WaitForSingleObject(NEmpty, 10) != WAIT_OBJECT_0)<br />
proWaitTime += 100;<br />
<br />
buffer[NxtIn] = c;<br />
NxtIn = (NxtIn+1) % bufferSize;<br />
if (NxtIn == 0)<br />
{<br />
scrWriteAt(0, 5, " ");<br />
scrWriteAt(0, 5, "Producer is waiting");<br />
}<br />
else<br />
{<br />
scrWriteAt(0, 5, " ");<br />
scrWriteAt(0, 5, "Producer is generating ");<br />
}<br />
ReleaseSemaphore(NFull, 1, 0);<br />
Sleep(sleepTimePro);<br />
<br />
proTime += sleepTimePro;<br />
<br />
<br />
}<br />
char Buffer::BufGet(void)<br />
{ <br />
char s; <br />
if(WaitForSingleObject(NFull, 10) != WAIT_OBJECT_0)<br />
conWaitTime += 100;<br />
s = buffer[NxtOut];<br />
NxtOut = (NxtOut+1) % bufferSize;<br />
<br />
if (NxtOut == 0)<br />
{<br />
scrWriteAt(0, 7, " ");<br />
scrWriteAt(0,7,"Consumer is waiting " );<br />
}<br />
else<br />
{<br />
scrWriteAt(0, 7, " ");<br />
scrWriteAt(0, 7, "Consumer is consuming ");<br />
}<br />
ReleaseSemaphore(NEmpty, 1, 0);<br />
Sleep(sleepTimeCon);<br />
conTime += sleepTimeCon;<br />
return s;<br />
<br />
}<br />
long Buffer::TimeProducerProduces()<br />
{<br />
<br />
<br />
return proTime;<br />
}<br />
long Buffer::TimeProducerWaits()<br />
{<br />
return proWaitTime;<br />
}<br />
long Buffer::TimeConsumerConsumes()<br />
{<br />
return conTime;<br />
}<br />
long Buffer::TimeConsumerWaits()<br />
{<br />
return conWaitTime;<br />
}<br />
it seems to me that the above does not work, and it always produce the same answer each run.

What OS do you design the program for? For example, you could get a quite accurate execution time of a thread using GetThreadTime().

|
|
|
|
it is for 2k! How about i just want to measure time of a part of thread? Thanks
|
|
|
|
|
Have a look at QueryPerformanceCounter and QueryPerformanceFrequency. It however displays the amount of "real" time used, not only CPU time for that thread. For the latter you can try GetThreadTimes.
|
|
|
|
|
I highly recommend Programming Applications for Microsoft Windows Fourth Edition by Jeffrey Richter. He demonstrates powerful Win32 API tools including the use of GetThreadTimes().

Hi,
In a follow up to my post below, there is going to be quite a bit of text displayed in the edit control. Insteaed of using multiple .Replacesel statement, can I store the text as a string resource and then display it using a single .ReplaceSel statement.
Also is the resource file the preffered method or this ?
Many thanks
Mike

You can use CString::LoadString to load the string from string resource and then use the loaded strind in ReplaceSel.
It is of course better to construct the text in memory and then call ReplaceSel once.

If the text is static then yes, it's good for localization.

Try the following:
CString str;
str.LoadString(<string resource ID>);
m_ctrEditLocation.ReplaceSel(str);

Hi guys,
I am trying to output some information to a user in a dialog based app.
I would like to use an edit control (multiline) to dislay several lines (30-50).
Is an edit ctrl the best way to do this ?
Also when using the
m_ctrEditLocation.ReplaceSel(_T("LINE 1 \n\n\r"));everything appears on the same line.
Could anyone suggest any ideas on how to split text up on multiple lines / improvements to enable me to do this.
Many thanks
Mike

You need to insert "\r\n" as line delimitter.
You can use this[^] modified edit control.

 Dear All,
1) Am in real trouble i have a text file i need to open this file and convert the contents of it into another charecter set i need to read the contets into hexadecimal format. how can i do this.
2) how can i change the contents of a file from an IBM machine into windows format i.e i need to change the charecter set from IBM charecter set into arabic or ascii charecter set.
thank you very much
Best regards,
Mohammad Zakarni

ummmmm all file data is just numbers remember so open it in binary mode ... read it into memory (if its not too big else read it chunk at a time) ... use a lookup table to convert between ebdic (ibm stuff) and ascii (the rest of the world) ... you should be able to find a conversion table somewhere by searching for ebdic on google for example
"... and so i said to him ... if it don't dance (or code) and you can't eat it either f**k it or throw it away"

I've been injured my eyes trying to find the logical bug (since it is
not syntax or any other error that could VC report), so I'm asking you
if you could help me to find the bug.
Program is retyped from book and unfortunately and don't have the
original source code to compare it with.
Program should create main window and in it the other four child
windows and do some display in each of them except the main window.
But when I try to run the program, it only display the main window and
the client area, without child windows in it!
Just to say one more time, VC does not report any error or warning, so
it must be the logical bug in code.
Here's the source (I apologize for text length in mail):

In WndProc's body you must:
<br />
case WM_SIZE:<br />
cxClient = LOWORD(lParam);<br />
cyClient = HIWORD(lParam);<br />
<br />
for (i = 0; i < 4; i++)<font color="blue">
MoveWindow(hwndChild[i], (i % 2) * cxClient / 2,<br />
<br />
(i > 1) * cyClient / 2,<br />
<br />
cxClient / 2, cyClient / 2,<br />
<br />
<br />
Should be enough...

Hello, all
Can anyone tell is a message cannot be peeked in a thread? for example:
Program 1:
LRESULT OnOK(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
MSG msg;
unsigned int nTimerID = SetTimer(hWnd, 1, 2000, 0);
while(1)
{
if( PeekMessage(&msg, hWnd, WM_TIMER, WM_TIMER, PM_REMOVE) )
{
MessageBox(hWnd, "Timer out", NULL, 0);
break;
}
}
KillTimer(hWnd, nTimerID);
}
Program 1 has no problem, the WM_TIMER message can be successfully peeked by PeekMessage. but please take a look at program 2.
Program 2:
LRESULT OnOK(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
unsigned long nThreadID = 0;
HANDLE hThread = CreateThread(NULL, 0, ThreadProc, (void*)&hWnd, 0, &nThreadID);
WaitForSingleObject(hThread, INFINITE);
return 0;
}
unsigned long WINAPI ThreadProc(LPVOID pvParam)
{
HWND* phWnd = (HWND*)pvParam;
HWND hWnd = *phWnd;
MSG msg;
unsigned int nTimerID = SetTimer(hWnd, 1, 2000, 0);
while(1)
{
if( PeekMessage(&msg, hWnd, WM_TIMER, WM_TIMER, PM_REMOVE) )
{
MessageBox(hWnd, "Time out", NULL, 0);
break;
}
}
KillTimer(hWnd, nTimerID);
return 0;
}
I run program 2 in debug mode, i found the timer is successfully created, but there just no WM_TIMER message. Later i changed the "WaitForSingleObject"(in OnOK function) into "MsgWaitForMultipleObjects", i found the WM_TIMER again, but it is returned by "MsgWaitForMultiObjects", not in the thread function.
I'm confused now, can anyone tell me how to peek a message in a thread?
