If you trying to retrieve content from Window/Edit box thats belong to some other process... then GetWindowText(..) api will not work..
You have to use WM_GETTEXT and WM_GETTEXTLENGTH message to reterive the text of that window.

You cant read the edit box because it not in you process however do not fret
lResult = SendMessage(
// returns LRESULT in lResult
(HWND) hWndControl,
// handle to destination control
(UINT) WM_GETTEXT,
// message ID
(WPARAM) wParam,
// = (WPARAM) () wParam;
(LPARAM) lParam
// = (LPARAM) () lParam;
);
Look up further documentation on the web but this will take care of your problem.

Hello,
At the moment Im writing on a code-comment macro that shall automatically generate comment-dummys for namespaces, classes, functions, etc., because I want to use my code with doxygen.
After matching with several problems Ive come to a problem I cannot solve myself.
Im using the CodeElements Interface to go through all elements and use the Comment-member of the CodeElement (eg. CodeClass) to set my comment-dummy.
In fact the problem is quite simple:
Visual Studio only assigns a comment to a CodeElement when it is looking like that:
// bla blub
// further blubb
but not if it looks like that
/* hrhr
*/
or that
//! codecomment
It wouldnt be any problem to make comments that are accepted by doxygen, but these comments are not assigned to the CodeElement and this way are not shown in the information-window that opens when you are goind to use the function in your source.
Is there a way to change this visual studio behaviour, so it would accept a comment like this as the comment assigned to the function?
/* void JustDoingSomething()
\brief does something
*/
void JustDoingSomething();
|
|
|
|
|
Hm, just forget about it - my visual studio now also shows the other comments - no idea why this wasnt the case before...

What is the conditions of displaying the message box?
From which function you display the message box?
Did you try with AfxMessageBox(...) instead?

Hi,
only a try
::MessageBox(NULL, "Your text", "Error", MB_OK | MB_ICONERROR| ... );

i want to chang the data of VT_DATE to the one of VT_BSTR with the VariantChangeType function, but only a part of the data is changed. for example,2005-12-20 0:00:00 is converted to 2005-12-20 of VT_BSTR, but 1899-12-30 21:30:00 is converted to 21:30:00 of VT_BSTR. both 2005-12-20 0:00:00 and 1899-12-30 21:30:00 are from sql server, and 2005-12-20 0:00:00 is smalldatetime; 1899-12-30 21:30:00 is datetime. how can i get the complete VT_BSTR data?

How do I lock a file pointer (FILE *) in MSVC? On Linux, this is achieved via flock(). In Visual Studio 2005, there's _lock_file() and _unlock_file(), but I can't fine any function in VS2003. So how can I implement file locking? I don't want to use LockFile(), as I already have all the functions implemented using stdio instead of windows file managment.
|
|
|
|
|
Use _fsopen() if you wan't to lock the entire file. It returns a FILE *, just as fopen().

Thanks for your reply, but I don't want to fclose the file afer each fread/fwrite. In fact, there will be multiple threads and processes trying to access the file, so each one needs to lock the file first.
|

|

Hello.
I understand your problem. Another way to do it is to use sopen() and lock(). But then you have to use handles instead of FILE *. But if that's not a big deal, check it out. lock() can lock regions of a file.

I am wondering why this code works:
<br />
<br />
#include <windows.h><br />
#include <tchar.h><br />
#include <stdio.h><br />
#include <stdlib.h><br />
#include <winreg.h><br />
<br />
int main(int argc, char *argv[]) <br />
{<br />
<br />
<br />
HKEY hk, hk2; <br />
DWORD dwData, dwDisp; <br />
TCHAR szBuf[MAX_PATH]; <br />
<br />
<br />
_snprintf(szBuf, sizeof(szBuf)-1, "SOFTWARE\\Microsoft"); <br />
<br />
<br />
if (RegCreateKeyEx(HKEY_LOCAL_MACHINE, szBuf, <br />
0, NULL, REG_OPTION_NON_VOLATILE,<br />
KEY_READ, NULL, &hk, &dwDisp)) <br />
{<br />
printf("Could not create the registry key."); <br />
return FALSE;<br />
}<br />
<br />
<br />
if (RegCreateKeyEx(hk, "Windows", <br />
0, NULL, REG_OPTION_NON_VOLATILE,<br />
KEY_WRITE, NULL, &hk2, &dwDisp)) <br />
{<br />
printf("Could not create the registry key."); <br />
return FALSE;<br />
}<br />
<br />
<br />
LONG retValue = 0;<br />
if ((retValue = RegSetValueEx(hk2,
"TestWrite",
0,
REG_EXPAND_SZ,
(LPBYTE) "data",
(DWORD) (sizeof("data")))))
{<br />
printf("Could not set the value., error=%d", retValue); <br />
return FALSE;<br />
<br />
}<br />
<br />
<br />
<br />
return 0;<br />
}<br />
1. I was expecting RegSetValueEx to fail as the key "SOFTWARE\\Microsoft" is opened with KEY_READ. Is it not the case that RegCreateKeyEx succeeds only if the samDesired parameter is only a subset of the one its parent key object is created with?
2. I need to write a registry wrapper class that prevents writing to HKLM. Does any one have ideas what is the way to go about it? I was planning to clear off the (KEY_CREATE_LINK|KEY_CREATE_SUB_KEY|KEY_SET_VALUE) bits before calling RegCreateKeyEx when the key is HKLM but any RegCreateKeyEx opening any sub key doesnt seem to inherit the access mode of its parent. Appreciate any ideas in this regard.
Thanks in advance.
