Especially when i is equal to 0. Then, referencing an array with -1 would be very suspicious.

If you suspect it is, then try:

@DavidCrow

Good idea and I tried that just now and it still failed after five times through. I have yet to try waldermort's suggestion, so let me try that here in a few hours, after I get off work and I will let you know if that fixed it. I am sure it is something very simple. I write in assembler too and when I first started I kept forgetting to initialise the DS in my code, went through everything over and over, got real frustrating but showed my code to a friend, he saw it and that was that. --something so simple it hurts. I bet that is what this is too.

Im off in three hours, talk to you again then. thanks guys.

Which indicates the problem (probably) has nothing to do with pkt_data.

I think your right, I am about to send my project or source to waldermort -- as soon as he tells me what he preffers. Hopefully, he will be able to look through it and correct the problem, or at least identify it better than I have.

I want to say, yeah it is the pkt_data variable, because when it is non-existant, my dll works, when it is existant, it fails. So it can't be the device I am reading from, which is what I first assumed. Then I thought maybe it was the file output portions, but if I remove that it still fails. I have no idea whatsoever.

It's a riddle. I am stumped.

best regards

Eureka. I have it working. After picking at it, it turns out I was leading us completly the wrong way --miles away. It happened to be from a variable further down in the code that deals with the hex dumpage, it becomes corrupt after a few times through the loop. Why, I have no idea as of now. However, it is now printing to the file as intended.

Hi ya'all,
I'm sure this might be a very easy and simple thing but I would like to find out how to package my project application so it can run without the developing environment; yes, just want to make it executable. Any pointers will be appreciated.

first of all, build it in release mode.
then, use the "Dependency Walker" tool to find which DLL are required
provide them with your exe, and use installshield (or any install packager) to provide an installer if you like...

MFC: Button press and release?

Rostfrei5-Apr-06 6:30

Hello!

I'm just a basic MFC user. Mostly I do my UIs in resource editor in VS.NET 2003. I know how to handle BN_CLICKED message from button and do something with it (trough message map). But now I have a problem. I should do something on button "press" and something different on button "release". It's the situation when event is dispatched on press and release not just release like it is the case with BN_CLICKED. Is it even possible?

Thank you for all the help.

Best regards,

Rostfrei

Which means you need to supply handlers for the WM_LBUTTONDOWN and WM_LBUTTONUP messages.

I managed to supply the handlers. I have the Dialog based application. If I press the mouse anywhere on the dialog I can detect it and can read the coordinates. The problem is when I click on the button. Click is not detected and I guess its intercepted by button. I want to detect the button down and check if mouse down happened in the area where button is. I don't have any method registered with the button. All I want to use it for now is button press/release shadow effect. What can I do? I don't want to draw custom button pictures and place them on the button region.

One way is to derive your own class from CButton and put the message handlers in it. If that does not work, perhaps message reflection will.

I already tried that but it is not possible to declare message map in there

<br />
class CCustomButton : public CButton<br />
{<br />
private:<br />
	DECLARE_MESSAGE_MAP ()<br />
};<br />
<br />
<br />
BEGIN_MESSAGE_MAP(CCustomButton, CDialog)<br />
<br />
END_MESSAGE_MAP()<br />

because I get error

<br />
mainAppDlg.cpp(106): error C2248: 'CDialog::GetThisMessageMap' : cannot access protected member declared in class 'CDialog'<br />
        c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\atlmfc\include\afxwin.h(2864) : see declaration of 'CDialog::GetThisMessageMap'<br />
        c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\atlmfc\include\afxwin.h(2767) : see declaration of 'CDialog'<br />

What is message reflection?

Sure it is. MFC would not be worth a whole lot otherwise.

Too lazy to download SDK for two files: Usp10.h,Usp10.lib

Hi,
Detecting a "Missing Character Glyph" without looking at a window

I am developing a dialog similar to Windows Word - Insert - Symbol Table Dialog.
For this all the charaters have to be displayed for the selected font (from all the existing fonts) and subsets which support the current font.
I am able to display the characters but some are appearing blank. These are the characters which are not supported by the the current font.
Can anyone tell me how to detect missing glyphs?
Till now I have tried with WideCharToMultiByte and GetCharacterPlacement.
But nothing seems to work.
I thought of using uniscribe function ScriptStringAnalyse.
Is this the correct function I should use?
Also I dont have Usp10.h and Usp10.lib on my system. Though I do have Usp10.dll
I thought of downloading same but looks like it comes as SDK package.
I just need this .h and .lib file.
Can anybody send me these two files?
Thanks a ton,
Arti Gujare

I know the SDK can be quite a pain to download, I managed to put it off for months and months, but 400mb laters, I already feel the benefits.

I would really advise you download it and burn it to CD. Scrounging files here and there will just end up causing more conflicts than a drunk french man in an english bar.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
