Hi,
My application is running fine , When Active Configuration is Win32Release and Project->Setting are "Use MFC in a Shared DLL"
but it crashes when Active Sonfiguration is same Win32Release but change the Project->Setting to "Use MFC in a Static Library"
it crashes at following code.
m_pListenSock is an object of CSock class which is inherited from CSocket class.
UINTCServerHandler::OnMsgStart(WPARAM wp, LPARAM lp)
{
m_pListenSock = new CSock();
m_pListenSock->Create (200); // It crashes at Create call
m_pListenSock->Listen ();
return 1;
}
Regard

So have you stepped into the call to Create() to find the offending statement?

This should work!!!
<code>
int nText = 12345;
char szText[10];
int nHex =0;
itoa(12345, szText, 10);
nHex = strtol( szText, NULL, 16);
</code>
Regards
Anil

Either write your own converter (multiply each digit with powers of 16), or convert to string using sprintf and convert back to hex using sscanf.

This makes non-sense. A number is neither in decimal, in hexa, or whatever else; it is just a number. Its representation may change but the number will always be the same. You can say 0x14 or 20 or 0b10100, all these three strings represent the same number.

Hallo
1. Well at least it makes sence. cause i have to controll some hardware. To calculate the needed commands the shortes way is to interprete int as Hex bit shift this and the result is the needed command.
Outherwice if you cant see the sence then become a lectural
2. int - char - hex is what i have and this is as fast doing a lot of if else
combinations - well but i need somthing fast - much faster ?!?!
Well the THX

123456 in base-16 is 0x1E240. Use itoa() or sscanf() to do the conversion.

Thanks for all ur support
I am looking for Win32 support.
and i am trying to use GetOpenFileName as suggeted by you all.
The my code snippet is:
<br />
OPENFILENAME ofn; <br />
char szFile[260];<br />
HWND hwnd;<br />
HANDLE hf;<br />
<br />
ZeroMemory(&ofn, sizeof(ofn));<br />
ofn.lStructSize = sizeof(ofn);<br />
ofn.hwndOwner = hwnd;<br />
ofn.lpstrFile = (LPWSTR)szFile;<br />
ofn.lpstrFile[0] = '\0';<br />
<br />
ofn.nMaxFile = sizeof(szFile);<br />
ofn.lpstrFilter = (LPCWSTR)"All\0*.*\0Text\0*.TXT\0";<br />
ofn.nFilterIndex = 1;<br />
ofn.lpstrFileTitle = NULL;<br />
ofn.nMaxFileTitle = 0;<br />
ofn.lpstrInitialDir = NULL;<br />
ofn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;<br />
<br />
DWORD err;<br />
if (GetSaveFileName (&ofn)==TRUE) <br />
{<br />
hf = CreateFile(ofn.lpstrFile, GENERIC_READ,0,<br />
(LPSECURITY_ATTRIBUTES) NULL,<br />
OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL,(HANDLE) NULL);<br />
}<br />
else<br />
err = CommDlgExtendedError();<br />
<br />
But i am returned with err = 0xFFFF .i.e.
CDERR_DIALOGFAILURE: The dialog box could not be created. The common dialog box function's call to the DialogBox function failed. For example, this error occurs if the common dialog box call specifies an invalid window handle.
Please help.

thanks for all the help.... but i also require the name of the function to open the open directory... like the one that opens when u try to set the directory for any application

Please check out Davide Calabro's CFileDialogST[^] class. Good luck and keep the good coding!

You still haven't told us if it's MFC or Win32, but if you just want to pick a directory you can use SHBrowseForFolder. Otherwise the function is actually GetOpenFileName. You can check out msdn[^] for more info

Hi,
I'm pretty new in programming in c++.net, and I was wondering if someone could help me out.
The goal is to control Abobe Acrobat so that it displays a pdf file in my own c++.NET application. I have found an example in the Acrobat SDK called ActiveView which is exactly what I want to achieve, but I have really no idea how it works.
Can anybody give me an explination of how it works, or how to make a start?
thanx!

Hello
I have a question ?
What is the advantage of writing ASSERT instead of VERIFYS ?
As far as I understood, there is no need of using ASSERT, as you can use VERIFY, because it works both in Debug and Release builds and ASSERT does not work in debug builds
Correct me if I am wrong.
Thank you
PS. I have written VERIFY(0) in my program(OnInitDialog) and built in Release mode, but it did not halt my program ?? why

the answer is there in your question.
If u use VERIFY in ur project u may need to delete all assert statement which u have used for debuggin purpose. So if there is only debugging purpose, use ASSERT and if something "should not" occur in your program at any cost use VERIFY.

ASSERT or _assert is for developers to make sure there nothing wrong during the development. When he/she is sure that everything is just fine, he/she compiles it in release build. ASSERT is defined as "nothing" in release build.

In release versions ASSERT evaluates to nothing. This means the statements given inside ASSERT are not executed. This could be trouble sometimes when you write statements like...
int i;
ASSERT( (i=GetI()) != 0 ); This statement won't execute in Release versions but will work fine in debug builds. In Release builds all statements depending on the value of 'i' will fail as the code expands to nothing.
In such cases use VERIFY. Which executes in both versions. But will only show an alert box in the debug versions.
int i;
VERIFY( (i=GetI()) != 0 );
