Some months ago I used this code to write a resource to a file:
FILE *outfile;
if (outfile = fopen(OutDLL, "wb"))
{
fwrite(dll, 1, dll_size, outfile);
fclose(outfile);
}
dll is a void*-pointer to the resource, dll_size the size of the resource

Thanks,
What I don't understand is how to address the resource. For example, I have a resource ID IDR_DB that I loaded at design time. How do I read it so as to write it to a file.
Thanks for help,
Ron

Yes. See here for an example.

hi
What do I have to do to maintain the layout of a Form when I maximize the window?
Is it possible to desig the GUI working in a window that is 50% smaller than the final GUI and configure the window to maximize when executing such that all the containers in the form maintain its position in relation to the borders AND resizes. (i.e. if I maximize the window from 50% to 100& I want all the containers to double in size as well)

(assuming you're using MFC/win32 UI code )
you need to handle the resizing of the UI manually, handle the WM_SIZE message and resize and reposition each control.
or you could use a layout manager, have a look here at CP for different layout managers.

Hi all,
i need your help urgently.
i am facing problem with posting a DoModal FileOpenDialog from property sheet. i will explian my problem this way.
I hava a dialog D1 derived from CDialog. in its OnInitDialog(), i created a propertysheet PS1 at run time with D1 as parent, and PS1 having WS_CHILD | WS_VISIBLE as creation styles. PS1 has 2 propertypages - PP1, PP2 - added to it. PP1 has OPEN button. On Clicking OPEN, i need to post FileOpenDialog Box. My code is as below:
D1.cpp
-------
BOOL CD1::OnInitDialog()
{
CPropertySheet *PS1;
PS1 = new CPropertySheet("", this, 0) ;
CPropertyPage *pp1 = new PP1() ;
CPropertyPage *pp2 = new PP2() ;
PS1->AddPage(pp1) ;
PS2->AddPage(pp2) ;
PP1->Create(this, WS_CHILD | WS_VISIBLE) ;
PP1->ShowWindow(1) ;
}
PP1.cpp
void PP1::OnBtnOpen()
{
CString fileName ;
char charFilter[256] ;
char fileExt[100] ;
char *filename ;
strcpy(charFilter, "File Filter (.mmm)|*.mmm|") ;
strcpy(fileExt, "mwf") ;
CFileDialog fileDialog(TRUE, // Open File Dialog
fileExt, // default extension
NULL, // Initial File Name
OFN_HIDEREADONLY |
OFN_OVERWRITEPROMPT |
FILE_ATTRIBUTE_DIRECTORY,
charFilter, // File Filters
AfxGetMainWnd() ); // Parent Window
if( fileDialog.DoModal() == IDOK )
{
return ;
}
}
my application hangs at fileDialog.DoModal().
Please help me in rectifying it.

filter always end by Double | operator i.e. ||.
this may be causing the problem.
right way to write charFilter is
strcpy(charFilter, "File Filter (.mmm)|*.mmm||") ;

How can I detect resource leaks in my VC code. There are several articles on CodeProject which addresses the memory leak detection however I couldn't find any about resource leak detection. Any ideas?

How are you confirming that resource leaks are happening?

I have a Windows application programmed in C (SDK level) using VC6. My Windows 98 and Windows XP (on different PCs) are set up with task bar "Always on top" & "Auto-hide".
With my application window having the focus and maximised, the task bar pops correctly in Win98 when I bring the mouse pointer to the bottom of the monitor, but on XP, the task bar does not popup.
I register the window as:
memset(&wc,0,sizeof(wc));<br />
wc.style = CS_BYTEALIGNWINDOW | CS_VREDRAW | CS_HREDRAW | CS_DBLCLKS;<br />
wc.lpfnWndProc = MainWindowProc;<br />
wc.cbClsExtra = 0;<br />
wc.cbWndExtra = 0;<br />
wc.hInstance = hAppInst;<br />
wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);<br />
wc.hCursor = LoadCursor (NULL, IDC_ARROW);<br />
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);<br />
wc.lpszMenuName = NULL;<br />
wc.lpszClassName = szAppName;<br />
<br />
RegisterClass (&wc);
and I create the window as:
hwndPrimary = CreateWindow(szAppName,
szPrimaryTitleBar,<br />
WS_POPUP | WS_BORDER,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
NULL,
hAppInst,
NULL);
and then do:
ShowWindow(hwndPrimary,sw);<br />
<br />
ShowWindow(hwndPrimary, SW_MAXIMIZE);
Note - I use window style WS_POPUP | WS_BORDER because I need maximum size client area. I can't waste space on title bar, thick border, etc.
If I do not maximise the window, the task bar pops up just fine, but the moment the application is maximised (which I need to do), the task bar does not pop up properly. The problem only occurs under Windows XP. When I run the EXE under Win98, the task bar pops up as expected.
Any suggestions?

Statically linking a project includes all code in dll into exe file, so the dll is no more needed on target machine, how can we do same fo activex controls, ie linking or using in such a way that they are included in exe and no more need for installing/registring on target machines?
|
|
|
|
|
Dll are never statically linked to an exe !! Lib files are statically linked but dll never (a lib file is the same that a dll file, except that here the linkage is static and with a dll the linkage is dynamic).
So, for activeX, you cannot statically link them to your project. You need to install and register them if you want to use them on a target machine.

Take a look at the EscapeCommFunction (for setting/clearing RTS and DTR) and at GetCommModemStatus to get the status of the CTS line.

Hello,
Is there a way to configure the way VC generates the #include statements?
- Keep/Generate header file names case sensitive. (When using the 'Add Variable' wizard to add a member variable to one of your dialogs, the wizard will add the name of the corresponding header file but using lowercase letters)
- Do not use 'Absolute' Paths. (When creating classes, it adds an absolute path to the base class header file when the base class is one of your generic classes)
Is there a way to configure this?.
Is this OS deppendent? (If yes, where to configure it?)

Hi All,
I try to create some simple applications using WindowsForms. I use Visual Studio .Net 2003, Academic version.
Lets say I have a form and a button.
When I double click on the button, I create an event for click. Then I can
write all the code to deal with that event, and everything works fine. The
only problem I have is that the code gets written in the header file, instead
of being placed in the cpp file.
I have some experience programming with Borland C++ Builder, and I compare the results with the ones from BCB.
I expect that when I add an event, the function definition should be placed in the header file, and the function implementation, in the cpp file.
Did I miss a setup option, or is there an option set up wrong? I don't consider normal that all the code gets written in the header file. What is the right procedure, so that when someone adds an event for a button, the event function to be added to the cpp file?
I tried to move the function from the header file to the cpp file, and to leave the definition of it in the header, but now I get a lot of errors.
To make it worse, the samples provided by Microsoft don't contain code in C++, only VB and C#. Is C++ dying, should I start learning C# instead?
Regards,
Nicolae

Did the application run?

No C++ is not dying. There are times when you need C++ to write an application. But you should learn C#, it`s the future language.
