LINK : warning LNK4089: all references to "MSVCIRT.dll" discarded by /OPT:REF youssef16-Apr-02 1:27 youssef 16-Apr-02 1:27  Hi, with this message, when I compile my soft, he can't recognize my members variable from a class. How can I do for recognize it ? Best Regards youssef Re: LINK : warning LNK4089: all references to "MSVCIRT.dll" discarded by /OPT:REF Tim Smith16-Apr-02 2:17 Tim Smith 16-Apr-02 2:17  Are you talking about in debug? Well, /OPT:REF is usually found with release mode builds and thus you wouldn't have any debug information by default. Tim Smith I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk? file properties 16-Apr-02 0:43 16-Apr-02 0:43  Can someone please help me, I'm trying to edit the poperties of an exe file. Right clicking the icon only brings up the general properties and not the other tabs. I want toget the program tab up so I change the path name. And there is also a check box for ms dos programs "Exit after Run" I want to uncheck that. Re: file properties Christian Graus16-Apr-02 1:57 Christian Graus 16-Apr-02 1:57  You want to edit the path name of an executable ? To change the path, you need to cut and paste the file. Klara wrote: And there is also a check box for ms dos programs "Exit after Run" I want to uncheck that. Where have you seen this dialog ? If you want a program to wait for you after it finishes running, you'll need to put in the code to wait for a keypress. As I've said already, I can't help you because I only know how to do that in C++, that is, using iostreams.

Re: file properties Christian Graus16-Apr-02 10:27 Christian Graus 16-Apr-02 10:27  I've worked it out - you want the tab you get for a shortcut, and it allows you to set the directory that it links to.

You need to impliment some degree of transparency between layers ( obviously, or you'll only see the top layer ). I'm told GDI+ actually draws using the alpha layer, so you could try that, it certainly supports colour keying at least. The Intel image processing library was what I used to write a paint program with layers, it also supports tiled images beyond what is physically possible for a Windows bitmap. rainfallc wrote: BTW: i used CTypedPtrArray to store every layer What are you storing pointers of ? If they are CBitmaps, you're going about it all wrong. They need to be DIBSections ( or GDI+ Bitmaps). I'd also recommend vector over dodgy MFC containers, or list or set if you want to be able to swap layers around.

Could u give me some more advices? i am not familiar with DIBSections , so could u show me some codes? thank u for your reply Re: how to write an eraser for layers Christian Graus16-Apr-02 10:47 Christian Graus 16-Apr-02 10:47  Ah, it's a DRAWING package ? You have one image, and you keep track of all the things you draw on it ? A DIBSection is like a CBitmap/HBITMPA, but it can be any bit depth, regardless of the screen depth. Are you using GDI+ ? How are you drawing the shapes ? Christian The tragedy of cyberspace - that so much can travel so far, and yet mean so little. "I'm somewhat suspicious of STL though.

Each layer has an array of pointers to a base class. Your WM_PAINT steps through these arrays in order and draws everything again to a CBitmap, then to the screen. rainfallc wrote: i used another CArray to keep track of which layer is hiding. Why not make a layer class that has a hidden property and holds all the things you are drawing, if you're doing it that way ? You're risking fragmentation between different aspects of what should be the same data. rainfallc wrote: please give me more hints OK. 1/ If you don't need W95 support, use GDI+. It's the easiest way to do layering 2/ Don't use CBitmap, because when you come to save & load images, you'll only be able to deal with images the same bit depth as your screen. Use GDI+::Bitmap, which has the advantange of letting you load and save a ton of formats as well. 3/ Don't draw everything to the screen every time, unless you want to be able to reselect items you have previously drawn to edit/move/delete them. If you're trying to write a drawing package, you're stuck with this, but I'd still impliment suggestion 4, and redraw a layer using your array only when you want to select/delete something 4/ Make a vector of layer objects, a class that encapsulates the bitmap that represents the layer ( which has it's alpha channel set so that it can be drawn on top of lower layers correctly ), the objects in the layer if you want to select them, if the layer is to be drawn or not, etc. Christian The tragedy of cyberspace - that so much can travel so far, and yet mean so little.

By erasing by reseting the alpha channel in just the layer you are drawing on. Making an eraser would seem to suggest you'd be better not keeping track of individual shapes, but just bitmaps. It's not going to take long for your paint method to groan under the strain of rerendering all this stuff. rainfallc wrote: u said: Make a vector of layer objects, a class that encapsulates the bitmap that represents the layer ( which has it's alpha channel set so that it can be drawn on top of lower layers correctly ) could u offer a short program for the suggestion above? do u mean to draw a bitmap with its alpha channel set on other layers` images? thanks again A short program ?

It allows a callback fn to be specified. Can anybody tell me, using the hwmd supplied in the callback is it possible to access the dialog's device context. Can this be done with Subclassing. Thanks for reading John Re: getting a dialog's dc Paul M Watt16-Apr-02 5:33 Paul M Watt 16-Apr-02 5:33  I have never used this function before, but does the HWND represent the dialog or the owner of the dialog. Anyway, you can always call GetDC to get the DC of a window. The thing that you will need to worry about is if that handle is the dialog or not. If that handle is the parent of the dialog, you can always enumerate through the windows to get your dialog handle, or cache a handle somewhere.

Memory), we don´t have time to chop it into smaller pieces ( now it´s not the time for that )... ... But we have like three more computers free, so would it be possible to send to that computers a bunch of files, and that machines could compile them ? ( so if I have 400 files I could compile 50 here, 50 there, 50..., in paralel). Does can be done on VStudio 6.0 ? And .net ? ... or that´s to good to be true ?
