Try to change write and read modes to binary L"wb" and L"rb"
|
|

A very subtle situation which is a great lesson for the future. Both your read and write loops contain no error checking. However having completed the write processing, a visual check of the output file suggests that the content is correct. The read loop reads sixteen values and prints them out, but does not check that you have read the full values every time. If you take a look at the file produced by this program you will see the hex value 'x1a' at character position 26. This character is taken by the fread() function as signifying no more data, so the last value read in is incomplete which gives the strange value printed by the program. Every subsequent read will fail so the value stored in memory is whatever was there previously; in this case the values that happen to be in the array storage space. The solution is to always check the results of your read and write statements, but in this case you also need to use "wb" and "rb" on your _wfopen statements to ensure the 'x1A' is not taken as end of file.

Thanks for all your replies.
I tried with "wb" and "rb" mode and its working fine.

Good news. But don't forget my comments about error checking, particularly when reading the file. Never assume that the file contents will be correct, however they were created.

I want to get the default value of the KEY from the registry
if( RegOpenKeyEx (HKEY_CLASSES_ROOT,
"\\AcroExch.Document\\Shell\\Open\\Command",
0,
KEY_QUERY_VALUE, &keyHandle) == ERROR_SUCCESS)
{
size1=260;
RegQueryValueEx (keyHandle,
"Default",
NULL,
&Type,
(LPBYTE)rgValue,
&size1);
sprintf (fnlRes,
"Default value your Windows system is:: %s",
rgValue);
}
I am not able to do so

I have created MFC dialog based application using VS 2008 application creation wizard.
In project settings if I use "Use Unicode Character Set" option, I cannot see winXP styles on any of the controls on the dialog,
and If I use "Use Multi-Byte Character Set" option, I can see the winXP styles.
Why this is happening? can't I use "Use Multi-Byte Character Set" option without losing WinXP styles to the control.
Some one please help me out with this issue.
Thanks in advance.
-Rajesh.

1. The two paragraphs are contradictory. The second one is correct. isnt it?
This is because common control version 6 supports only unicode and a dependency to comctrl version 6 is only inculded if the unicode is enabled. Check the stdafx.h you can see the following lines
#ifdef _UNICODE
#if defined _M_IX86
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*'\"")
#elif defined _M_IA64
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='ia64' publicKeyToken='6595b64144ccf1df' language='*'\"")
#elif defined _M_X64
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='amd64' publicKeyToken='6595b64144ccf1df' language='*'\"")
#else
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")
#endif
#endif

Actually, if you remove the
#ifdef _UNICODE and the corresponding
#endif the common controls will still work with MBCS and give you the XP look.

Hi All,
In my application I need to execute some commands. For that I am making a .bat file and execute it using Shellexecute(). It is working well for Vista32 bit, but in Vista64 bit machine Shellexecute() is not running these commands(i am running with Admin privileges also). Does ShellExecute() not support Vista64 bit?
Is there any other way for Vista64 bit.
Thanks
Madan

It's probably some error in your batch file.
First run the batch file manually and check if all the commands work.

Thanks for replying. Yes all the commands are correct because if I run this batch file with command prompt then it execute successfully.
Let me explain- I am running following three commands command1)- bcdedit /set {bootmgr} device boot > D:\m1.txt
command2)- bcdedit /set {default} device boot > D:\m3.txt command3)- bcdedit /set {default} osdevice boot > D\m2.txt.
These three commands clears Bootmgr of Vista.
For runnong these commands I make a batch file and execute it with ShellExecute() For seeing output I used pipe. Then after ShellExecute() if I see these m1,m2,m3 files then these are blank.
I am confused now.

How can we get the acrobat path reader exe path in VC++
|
|
|
|
|
Why do you want the path?
Is it so that you can use it to launch a PDF file?
If so, you don't need to know the path.
You can simply use ShellExecute to launch it.

It's not because of my post Mr. Crow. 
I've gave him this answer after I saw his post about the exe path.
I knew that you will give him the right directions about the exe path and decided to show the OP how could he pass cmd line args to Acrobat reader in order to select given page.

Hi deadlyabbas,
Did you try searching the Adobe forums[^] before asking in the C++ forum?
Best Wishes,
-David Delaune
|
|
|
|
|
Try
SearchPath[^]
Pass "AcroRd32.exe" as lpFileName to that function.
|
|
|
|
|
Use FindExecutable().

I am trying to widen drop-down part of combo box but keep fixed size of combo box.
For the same i used following in my code. But drop down portion of the combo box remained as it is.
No change reflected in it's size.
LRESULT OnDropDown(WORD wNCode, WORD wID, HWND hWCtl, BOOL & bH1)
{
::SendMessage(v_ComboBox->v_hWnd, CB_SETDROPPEDWIDTH, 100 , 0);
::SendMessage(v_ComboBox->v_hWnd, CB_SETHORIZONTALEXTENT , 100 , 0);
}
Please help to solve this issue..

CB_SETDROPPEDWIDTH is used to set the maximum allowable width and not the exact width of the drop down list.
In your case the drop down list will grow up to 100 pixel if you have lengthy strings as its items.
For fixing a large width to the drop down, you may need an owner draw combo box.
This article could be of help - FontComboBox - a font listing combo box for .NET[^]

I guess thats not correct. To confirm I just tried the code and the width of drop down changed to 100( Provided the width of combo is less than 100 pix ).
