I'm looking for a tool to quickly implement syntax coloring in a RichEditCtrl. Most of what I have seen appears to be complex for the sake of being complex. Any suggestions to chase down some tools or some direction in creating my own would be greatly appreciated. I have created my own syntax coloring, but I'm not happy with the performance or flexibility.
Thanks!!

I have a problem when rendering a document in a CScrollView derived class. I started with both a simple approach (a version of HexView from a sample included with the book, "Windows 95 MFC"), and a more complex one from an MS site. In each case, everything "almost" works. However as you scroll, on occassion, it appears as though a remnant from a previous line persists. In adapting these two approaches, the problem either doesn't exist with the original code or is minimal. It is only when I try to add my own data that the problem shows up. Initially I thought that I had incorrectly adapted the sample's logic and while that is probably the case it is not obvious.
In both cases, the sample code is retrieving data from a file - reading the data into an array then pulling out the appropriate number of array lines for display. What I am trying to do is the equivalent of dynamically adding some data to what is pulled out of the array and appending that data for display in the view. The reason is that once I can determine the real problem I will use the logic to display information that is interpreted (not a one::one relationship with what is on the file/document).
Anyway, that is when the problem is exhibited, once additional data is added that wasn't retrieved from the file.
The problem must be obvious, but I don't see it.
There was too much code to try to decide what "snippet" would make this more understandable, so I havent included any. But I figured I am not the first person to run into (or create) this problem and maybe one of you have had the same problem.
Any ideas would be appreciated. Thanks - Mike

Hi everybody,
I have a problem with my dialog base window :
when "enter" or "escape" key is striked, my window is destroyed by OnDestroy().
I don't know why and how easily avoid this.
Could someone help me please?
Thanks.

Handle OnOk() for enter and OnCancel() for escape, in which you prevent the program from terminating.

Hey Guys
does anyone know how to enumerate all the key containers using the crypto API and then get them displayed in a list box which the user can select one from. I have written what i think should work but it doesn't it just ends up displaying a null string ie iiiiiiiiiiiiiiiiiiiiiiiiiietc so my guess is the key stores arn't even being read and put in the string.
Your Help Is greatly Appreciated

to tell the truth, im quite embarrassed to ask this question.
is it possible for me to still use the resource editor even though i will not be using mfc? 
you see, i'm new to visual c++, a newbie, and can't seem to understand the intricacies of the language, particularly mfc. i've decided that creating applications using the basic win32 windows api, without the use of mfc, would be a nice start for me. please tell me if this is true. or better yet, just answer the question. 
|
|
|
|
|
yes. I suggest that you read a book about visual c++.
|
|
|
|
|
i have. there's not much about books about visual c++ from where i am. the thing is, its a programming reference book. class listings, fields, methods ang all that stuff. not much about explaining the programming environment. if you please, kind sir, could you explain it do me, if it won't bother you.
|
|
|
|
|
What exactly do you need explained?
You can order books via the internet, you know..
|
|
|
|
|
thank you for your interest to reply. i need the resource editor explained, if you please. 
i am just a student. i have no income and books cost a lot. that is why i resort to programming reference books...best 'bang' for the buck.

If you can't afford to buy books ( and I was a student once too, so I know how you feel ) then I'd suggest looking for free books on the net. It's a poor substitute but could be your best bet for now. However, if you're serious about it, you *will* have to spring for some books eventually. Look at the list on this site for books that are highly recommended so you don't blow your cash.
However, it sounds to me more like you need to learn C++ before diving into Windows or MFC. MFC makes Windows programming *easier*, not harder. I'd recommend going Win32 AFTER learning it in MFC, unless you own Pethold's book, but even then, I still think it is more complex.
The resource editor allows you to create things like menus and bitmaps which you can load from the resource, meaning they are stored in your .exe file. The dialog editor allows you to design a dialog box, then you can double click on it to create a class that uses that dialog template, and use the class wizard to add message handlers for events and controls on the dialog.

i seem to have not placed my question correctly...
here is the problem. if i dont use the mfc, i seem to create the components in my program during run time. when that happens, it is my impression that i *cant* use the DIALOG editor. i shall ask this quesion:
is it possible to use the dialog editor, even though i will not use mfc?
it is also my impression that mfc will make my program easier to write but after several tries and several programs later, i still cant understand all that other stuff that gets included in my programs. that is why i think i will do better without mfc. thanks

I don't know if it can be done.
I would suggest again that you don't need to understand every line of code you get for free from MFC, you just need to learn bit by bit as you use them. You should also use the msdn online as much as possible, and there is a ton of online help for MFC there.

If the question is: can I use the Resource Editor in a Win32 application, not using MFC?
The answer is: Yes, sure!
If you create a new project with AppWizard, choosing Win32 Application -> Hello World , you can see the About dialog in the project's resources and all the other resources as well.
Is there something I missed?

Yes, you can use the resource editor without using MFC. I write programs all the time that do not use MFC but have dialogs, menus, icon, string, etc. I use the resource editor to create my dialogs, menu, icons, and string tables.
All the resource editor does is give you a graphical tool for editing the .rc files. There's no MFC involved when it comes to editing resources.

I thought that might be the case - how do you connect a class to the dialog template - is it just by putting in the enum
IDD = IDD_MYDIALOG
and passing IDD into the Create method ?

Using ATL (IDD = IDD_MYDIALOG), yes. Otherwise you have to call CreateDialog and pass in the resource ID.
HWND CreateDialog(
HINSTANCE hInstance,
LPCTSTR lpTemplate,
HWND hWndParent,
DLGPROC lpDialogFunc
);
lpTemplate
Identifies the dialog box template. This parameter is either the pointer to a null-terminated character string that specifies the name of the dialog box template or an integer value that specifies the resource identifier of the dialog box template. If the parameter specifies a resource identifier, its high-order word must be zero and its low-order word must contain the identifier. You can use the MAKEINTRESOURCE macro to create this value.
And the tricky part is to call IsDialogMessage in the message loop if you're main window is a dialog.

i've seen msdn and it does provide a LOT of help but not enough for me apparently...
i now see that it is possible to use the resource editor without mfc.
does it mean i can create a win32 .exe 'empty' application and i can still use the resource editor?
if the answer is yes, then i still have a few questions...
do i need to edit my own .rc file?
how do i link my class to the resource editor?
it really seems that the resource editor has no idea as to what i'm doing in my code thereby it cant see what components i'm using that is why i cant use the editor... i'm really confused.

yea u can use the resource editor without mfc, i'm a beginner too but i found out it was really easy to use mfc, u really should try it, especially when u already know a bit of visual basic its really easy. I started out with c++ with Dev-C++ (www.bloodshed.net). it doesn't have a resource editor u just have to do it manually with that one but i converted a win32 api example that show a simple window on the screen to a dialog application. i'm not going to enter the code here but you can find some help at: http://www.winprog.org/tutorial/
i will post the code here as soon as i can, i think this is a very interesting question because it was one of the first questions i asked myself too, because when u use resources for dialogs u can just draw them in the MSVC resource editor and u dont have to program everything in code + the final executable remains very small (in dev-c++ only 5kb or so, in MSVC about 24kb). I will send u both the code for dev-c++ and MSVC++ as soon as i can. i recommend u take a look at MFC and try to use the classwizard. A very helpfull tool  , when u have a dialog in mfc and draw controls on it u just go to View>classwizzard> member variables and u double click the controls u want to acces, u then enter a name for the handle and press ok. fromt hat point on its as easy as VB really. for example u've drawn a textbox on a dialog and u declare a variable for it called m_hText. when u want to put something in the textbox it would look like this:
m_hText = "coffee smells bad";
UpdateData(false);
its that easy!! u just put the code where u want it to happen as in OnCreate(). UpdateData(); is used for the interaction between de member variables and the dialog. When u use UpdateData(false); the values of the member variables are displayed in the dialog, if u use UpdateData(true); the entered values in the dialog are stored in the member variables. Ugh i'm gonna stop now :p i'll just mail it

Hey Guys
I really need help i want to be able o convert an unsigned char array (unsigned char string) to a standard char array (char string). I need this becaue i want to put the available key stores returned from CryptGetProvParam which will only take a pointer to a unsigned char into a list box which only takes a pointer to a standard char string.

Doesn't cast work?
unsigned char * pBuf;
char * pString = (char *) pBuf;

Hello,
I want to be able to display a dialog (connect to database) before my view is displayed.
The dialog contains my connect information and I've included a variable based on the dialog class in my Document class.
In my main application I put following statement:
cmdInfo.m_nShellCommand=CCommandLineInfo::FileNothing;
This works fine.
I have a problem to figure out in which function I need to call the GetDocument()->m_dlg.DoModal()
I tried in OnCreate of my view, but I don't know what function to call if I press the cancel button in my dialog so I don't see any document/view. If I call return -1 in CMMyView::OnCreate, I get an error message saying that the creation of my view was not succesful.
If I put the DoModal in OnInitialUpdate I already see the docuemnt window and this is not what I want.
Please help me out on this one
Thanks
Wim Jans

Not sure if this will help or not, but...;)
Try overriding OnFileNew in either your Doc or your View class. More than likely in your Doc class. Just make sure you return the function to the base class so that It can finish processing it correctly.
If this tip helped it was written by me, if not I don't know who wrote it.
