Hi,

You know when you load a non-normal resource it will open it in some sort of Binary or Hex viewer? Could someone explane very precisly what all of it means? There are three columns, one on the left that appears to mark lines, one in the middle that appears to have the data, and some strange column on the right. I'm most interested in the column on the right.

Thanks,

else who learned to spell after 1976] blame it on

I believe the right most column tries to show the data as text.

The three columns are in order:
1 Offset - the hexadecimal offset of the beginning of that line (within that resource)
2 Data - hexadecimal representation of that "line" of data. Often 16 bytes is represented/line.
3 ASCII representation of that data.

Is there a way to copy the "data"? Every time I try, I get the ASCII part of it?

What you get on the clipboard is the raw data. No, you can't copy the ASCII representation of the hexadecimal representation of the data. You can however paste it into a "binary file" (MSVC term) window, save that, and then use some "hexdump" command-line utility to get it.

No, I won't write a hexdump utility for you. Smile | :)

addin/program that display dialog resource with resource_id

Any program that does this?
This is required when i want to know the resource symbol/ID of the control on the dialog quickly. I hate clicking on properties and finding out what the symbol is.

This is used for ETSLayout, when i'm adding the controls to the panes.

Thanxs in advance!

unresizable dialog

I need an unresizable dialog. I was thinking of getting the size at the beginning of the program then if the user tried to resize it I would just reset it back to the original size. However, I've seen programs that don't even display the resize arrows. I tried playing with the dialog settings but it doesn't seem to work. Any ideas?

dialogs are unresizable by default, and you can disable the max/min/restore buttons in the resource editor.

hmmm, well my dialog is resizable. Do you know what the default settings are? When it is a popup or overlapped dialog it crashes when the program starts. When it is a child it works, but I can't add/remove the min and max buttons. It is a dialog based app. Is that the problem?

go in the resource editor, open your dialog. click the Styles tab. choose "Dialog Frame" as the border type. click Title Bar and System Menu. (and min/max boxes, if you want). those are the defaults.

Unhandled exception when filling up bmiColors property in BITMAPINFO

redeemer20-Jun-02 13:48

20-Jun-02 13:48

The unhanlded exception error appears at different times when i run this code. Sometimes when i is 100 and sometimes when it's 500.

for (i = 0; i < horzres*vertres; i++)
{
    bInfo.bmiColors[i].rgbRed = GetRValue(pCol[i]);
    bInfo.bmiColors[i].rgbGreen = GetGValue(pCol[i]);
    bInfo.bmiColors[i].rgbBlue = GetBValue(pCol[i]);
    bInfo.bmiColors[i].rgbReserved = 0;
}

Thanks very much in advance!

If you're trying to fill a bitmap with data, they are word aligned internally, and you need to skip the padding at the ned of each row. My GDI+ image processing articles show how - the principle is the same in C++/GDI because the internal structure is the same.

WHat do i do when a struct requires a "RGBQUAD [1]" type?

redeemer20-Jun-02 12:44

redeemer

20-Jun-02 12:44

The BITMAPINFO struct is defined as follows:

typedef struct tagBITMAPINFO { 
  BITMAPINFOHEADER bmiHeader; 
  RGBQUAD          bmiColors[1]; 
} BITMAPINFO, *PBITMAPINFO;

It's the bmiColors[1] property i'm confused about. This requires an array to RGBQUAD structs and all i have is a pointer to an array of them, how do i use the pointer when it wants an array?

Thanks

Re: WHat do i do when a struct requires a "RGBQUAD [1]" type?

20-Jun-02 12:54

MSDN :
The RGBQUAD structure describes a color consisting of relative intensities of red, green, and blue.

typedef struct tagRGBQUAD { // rgbq
BYTE rgbBlue;
BYTE rgbGreen;
BYTE rgbRed;
BYTE rgbReserved;
} RGBQUAD;

Members
rgbBlue Specifies the intensity of blue in the color.
rgbGreen Specifies the intensity of green in the color.
rgbRed Specifies the intensity of red in the color.
rgbReserved Reserved; must be zero.
Remarks
The bmiColors member of the BITMAPINFO structure consists of an array of RGBQUAD structures.

And keep in mind that an array is a pointer!

u can always write:

int a[5];
a[1] = 2;

*(a+1) = 3; // Means a[1] = 3;

This bmiColors is the tip of a variably-sized array of RGBQUADs. Suppose for instance your palette has nBmiColors entries, you'd allocate and stuff the thing like this:

unsigned nBmiColors=256;
BIMAPINFO* lpbmi=(BITMAPINFO *)malloc(
  sizeof(BITMAPINFO)+
  nBmiColors==0?0:(nBmiColors-1)*sizeof(RGBQUAD));
for(unsigned n=0;n<nBmiColors;++n)
{
  lpbmi->bmiColors[n]=...;  
}

MDI windows - using FileNew and FileOpen

20-Jun-02 12:20

Hello,

I don't know if someone could help me with this, but if they could I would very much appreciate it. I created a very basic MDI application to let me open Bitmaps. So that works fine. I click Open, select a bitmap, voila, my Bitmap appears! Cool | :cool:

But, when I start this program, it comes with one blank window open. If I decide to close this window (or if at any time I decide to close all windows) and have no windows open, I encounter a problem I'd like to fix. If I hit Open, and select a Bitmap, it opens a new window, but no bitmap appears. It is simply a blank window. I want the bitmap I had chosen to appear.

I tried to use OnFileNew, or even CWinApp::OnFileNew, but it tells me these methods are protected. If I take them out of protected and make them public, funny enough, it STILL says they are protected. I am sure that making them public instead of protected is the wrong way to do this, but I am currently out of ideas.

If anyone knows how to make file->open open a new window as well, I'd really like to know how you do it.

Thanks a whole lot,

Nick One

The CDocument derived class has an OnNewDocument method ( or something similar ), and that is where you want to do it.

To stop a window being opened at the the start of your application:

// stop a new document being created if just run normally
if (cmdInfo.m_nShellCommand == CCommandLineInfo::FileNew)
    cmdInfo.m_nShellCommand = CCommandLineInfo::FileNothing ;

Just before the call to ProcessShellCommand()

About Dialogs

20-Jun-02 11:40

Hi,

I have a MDI program, this program starts a Dialog using doModal function, but this function stop the main window, and wait for a user resp (press Ok or Cancel). I need that this main window don't stop ..

How can I do that?

Re: About Dialogs

Joaquín M López Muñoz20-Jun-02 11:51

Use a modeless dialog (search for info on your docs, basically you create and show the dialog without calling DoModal and keep on with your program, later on someone has to take care of destroying the dialog when the window associated exits.)
