This is sort of related to a question I had before. I'm writing a program that needs to have an edit control with a very specific format. It needs to have a format of L#LLLL#########LLLL### (where L is any letter A-Z and # is any number 0-9). I'd like to write this control from scratch since this is a type of learing lesson for me. I'm wondering if the best way to go about this is subclassing the CEdit control. If not some ideas on the best way to go about this would be much appreciated. Thanks.

Take a look at these[^] before you write code...

I've got an app that has several static libraries. In the main App I've defined several dialog resources that I want to implement classes for in my static libraries. When I create the classes and put them in my static library I can no longer associate members or message habdlers with the class and the Dialog Resources using the wizards and such in VS. Is there something that I can do to get this working?
I'm using VS.NET 2003, coding in C++.

Hi everyone!
I have a CString variable and it must be passed in a function as TCHAR. I don't know how could I convert it. Does anybody knows?
Thank you in advance! 
|
|
|
|
|
SomeFunction( TCHAR ch )
{
...
}
CString str;
SomeFunction(str[0]);
will work.

TCHAR is simple "char" type. If you want to pass CString data into a function, you should use "TCHAR*" instead of "TCHAR". Example as below.
void f(TCHAR* prm)<br />
{<br />
do something<br />
}<br />
<br />
void main(void)<br />
{<br />
CString szPrm;<br />
f(szPrm.GetBuffer(szPrm.GetLength()));<br />
return(0);<br />
}
Otherwise, you can pass only one character into function.

Now it works perfectly, thank you

If you do this you should also call szPrm.ReleaseBuffer(). The MSDN doc says the following:
If you use the pointer returned by GetBuffer to change the string contents, you must call ReleaseBuffer before using any other CString member functions.
If you are not going to change the string the following should work (LPTSTR)(LPCTSTR)szPrm

Hello.
I would to know how efficient is an assorted CListCtrl's search feature. In other words, is CListCtrl's find feature efficient when finding random item in a list that is assort? Is it faster than O(n)?
Thanks,

Hey everyone,
I am currently working with some windows styles i.e. WS_SIZEBOX, WS_OVERLAPPEDWINDOW, WS_MAXIMIZEBOX, WS_MINIMIZEBOX, WS_SIZEBOX, etc. Is there a way to create my own windows styles? I am assuming you can do it with enum? but not really sure.
Thanks everyone

|

Mm..
No, I don't think that you can override the default type flags. Basically, the window style flags determine both how the window is painted and how it behaves. This having said, you can override the WM_PAINT function in order to paint your window in any way you can imagine.
Providing different functionality of the window is all about writing custom handlers for different messages the window receives. For example, the sizing box is drawn around the window, it's client area is reduced, and then a hit test is made if the cursor is over the sizing area. The window flags enable you to gain some basic functionality provided by Windows, but again, I don't think you can create your own flags.
This is because if you created new flags, you'd need to hack the Win32 API to determine what these style flags mean. Of course, if you derived an MFC CWnd, you could create custom window flags for your own windows that determine certain painting and/or behaviour styles. But this is not about creating new styles, more like extending the already available ones.
It's difficult to answer your question, but perhaps my ramblings shed some light on the issue

hi,
i have modified the code of brochure machine which is available in the MSDN for my requirement.
what the earlier Code does??
----------------------------
It gets the handle of current IE instance get the handle of the document and invokes print command on the OLECOMMAND TARGET
Earlier Code snippet(Microsoft)
----------------------
launcPT()
{
CComPtr<iolecontainer> spContainer;
CComPtr<iserviceprovider> spSP;
CComPtr<iwebbrowser2> spWB;
CComPtr<idispatch> spDisp;
CComPtr<ihtmldocument2> spDoc;
CComPtr<iolecommandtarget> spCT;
CComVariant vPTPath = "res://CramerPrintControl.dll/PT.htm";
m_spClientSite->GetContainer(&spContainer);
spContainer->QueryInterface(IID_IServiceProvider, (void**)&spSP);
spSP->QueryService(SID_SWebBrowserApp, IID_IWebBrowser, (void**)&spWB);
spWB->get_Document(&spDisp);
spDisp->QueryInterface(IID_IHTMLDocument2, (void**)&spDoc);
spDoc->QueryInterface(IID_IOleCommandTarget, (void**)&spCT);
spCT->Exec(&CGID_MSHTML, IDM_PRINTPREVIEW, NULL, &vPTPath, NULL);
return S_OK;
}
----------------------------
I want to print the document which is residing in one of the frames of the document ,so i traverse through the frame collection and get the document in the desired frame and try to print it.when i try to do this,after repetitive invokation,the IE crashes,i dont know the reason may be there is a memory leak in my code or may be i am doing something wrng.i am new to vc++.so please have a glance at my code and point out the problems.
i am really stuck here.

(1) What character set do you display with? UNICODE? MBCS? etc...
(2) What language packs do you have installed on your computer?
(3) What operating system?

I guess!  The problem is that my contact in Israel, whom have the Hebrew package installed, told me that all the strings in my app were ???????. Should have mentionned that earlier 
One thing that I should mention is that the string table language's is Hebrew but the dialogs are in english. Perhaps the problem lays there?

Does your friend's default locale is hebrew and what locale do you use in your program, default ?
Note : it seems better to use STL's locale class to set the locale, rather then win api directly, this all locales are set the same, win32 and c runtime.
I would recommend to switch to Unicode, it is so much easier to deal with, especially when you mix two or more langauges, the effort might well worth it. Also, try to install hebrew support on your machine (On my w2k it's in Control Panel\Regional Options\General tab, check hebrew, don't have xp machine nearby, but beleive it's in the same place). And of course the font you using must have hebrew charset.

Here's what I did so far :
in the .rc files :
#if !defined(AFX_RESOURCE_DLL) || defined(AFX_TARG_HEB)
LANGUAGE LANG_HEBREW, SUBLANG_DEFAULT
#pragma code_page(1255)
...
...
...
I did change every dialog's language to Arial so it can show Hebrew
FONT 8, "Arial", 400, 0, 0xB1
Heck, the editor won't even open the .rc file anymore because it says it's in Hebrew... so I guess the .rc files are fine!
Every place that I could find English as the language I would set it to Hebrew.
Now, in the Outlook toolbar and in the system menu's, the strings are showing correctly (I have Office 2003 and I added Hebrew) but all my dialogs are showing ?????????. I haven't been able to set Hebrew as a language for Windows XP. I'm using LoadString, is there something particular to do?
It's not showing correctly on my computer but I'll check with my contact in Israel...

I looked at the page you've sent. Does "arial" on your system has hebrew charset ? Since the menus are shown corretcly you can try to change "arial" to "MS Shell Dlg" (it's probably mapped to "Microsoft Sans Serif" whatever it is it has hebrew char). Since the title and labels appear to be RTL I assume you have set code page to hebrew.
LoadString loads the string for your current thread locale (same applies to DialogBox, FindResource etc.), this way you can have resources for multiple languages in your resource file and those functions will try to find the closest match for the current thread's locale.

Ok, so far I've been 30% successful : the toolbars are showing correctly and some controls in my dialogs are fine as well (see link for screenshot). I was also able to display Hebrew correctly on Win XP and in Visual Studio.
Why are there some controls that won't display correctly?
