Ops, I have only a little experience working in turbo c graphic. I guess you might be using the
initgraph() to intialize the graphic screen isn't it? At the time when I worked in TC++, the graphic driver that came with the TC allowed me to set only a maximum 640X480 resolution. I think now they will be providing some new drivers. Get it and copy it to your TC\BGI folder also specify this file in the initgraph function.

Then why did you ask a "through C++" question in the VC++ forum?

try mode 13h... or it's better you shift to Windowsprogramming.. graphics programming is pretty much easier in windows programming..

Hi
I am a beginner visual c++ programmer and I have a difficulty.
There are two buttons on a dialog box and both of them will create a new dialog box.In the new dialog box I should know which button is pushed to create this dialog box.I tried CButton::GetState() method but it did not solve the problem because I think this method is for radio buttons.So how can I know which button was pushed.
Thanks

in the resource editor, open your dialog template, and double click on the button which is supposed to open another dialog. it will ask you to give a name to the event handler being created. press enter, and place your code there...
also, maybe this[^] could help.
|
|
|
|
|
when a button is pushed OnBnClicked(button name)() function will be executed and you will know which button is pressed. put message box in each of the button clicked functions with different message
|
|
|
|
|
But can I use the event in a different dialog box from the dialog box which the event is created.Because I want to know in the second dialog box that which button is pushed in the first dialog box.
|
|
|
|
|
can you show me the code whr u are calling the new dialog(or creating a dialog)
|
|
|
|
|
thanks
I solved the problem from another way.

So why not just pass some sort of identifier to the new dialog's constructor?

I am implementing a CString object and I want to convert a string in CString to char buffer.

|
|
CString str;
Use str.GetBuffer() and str.ReleaseBuffer()
|
|
|
|
|
I dont how to convert from CString to char buffer but you can get a char by using variablename.GetAt(int CharAt) function
|
|
|
|
|
CString str = "hello world";
char pszStr[50] = {0};
::strcpy(pszStr, <code>(LPCSTR)</code>str);
never use GetBuffer, until you need to modify directly the internal CString buffer. the CString class provides some useful cast operators, such as the one quoted here

I believe the more correct cast would be LPCTSTR.

not quite.
LPCTSTR is when dealing with TCHAR. here, i woluntarily used char, because i didn't want to enter unicode types considerations (and i didn't know the equivalent strcpy() function  )

wcscpy(), or _tcscpy() if you are supporting both.

If you're using CString then you're using TCHAR.
For CString, LPCTSTR is appropriate.
For CStringA. LPCSTR would be ok.

No cast is needed in this situation, the following code works identically:
CString str = "hello world";
char pszStr[50] = {0};
::strcpy(pszStr, str);
Casts which are not needed – especially when they are C-style casts – are a pet hate of mine. Note the whole LPCTSTR vs LPCSTR is no longer an issue as such.

in this code how can one call the button clicked function on pressing enter. i have tried adding virtual void OnOK(); but still the enter key doesn't execute the button function but now the dialog is not closing.
I have used a CxSkinbutton class which creates button with different skins. do i need to add a function in that class to capture the enter key

I didnt check the CxSkinbutton and all...
But wish to tell you that, if the return vaue of the WM_GETDLGCODE message send to the button didnt contain the DLGC_DEFPUSHBUTTON values set, the button will not respond for the enter key. Try overidding the WM_GETDLGCODE message and passing DLGC_DEFPUSHBUTTON too with it..
UINT CxSkinbutton::OnGetDlgCode()<br />
{<br />
return CButton::OnGetDlgCode()| DLGC_DEFPUSHBUTTON ;<br />
}
