It depends on the type of file, for a plain text file i'd use MEMO or TEXT, if it was a binary file your best bet would be BLOB or BINARY.
I'm not sure if these are the MS SQL Server types or one of the many other DB's i've used

Hello all,
I am working at a MFC application and I am using the STL containers also. The problem is that I am trying to use valarray and when I include
[pre]
#include <valarray>
[/pre]
I get all sorts of compiling errors

Error executing cl.exe.
[/pre]
However it compiles fine in a Console App.
Anybody have an idea?

Include valarray like this:
#undef min
#undef max
#include <valarray> The problem stems from some pesky min and max macros defined in windef.h that interfere with valarray::min and valarray::max.

Thank you Joaquin, apparently they fixed this in VC 7.0

Does anybody know how to access Ports in Windows NT?
|
|
|
|
|
What kind of ports? Message ports?
Now that we've taken care of the educational bit (be precise), I assume you want to access some I/O port (serial, parallel, ...).
You talk to (or even write yourself) a device driver. Try searching Google for something like "Windows NT direct I/O".

Anyone know how to disable the list control from automatically displaying a vertical scroll bar when there are too many items to display?
I tried the LVS_NOSCROLL style but this disables scrolling entirely. I just want to get rid of the visual scroll bars but still have the ability to scroll the list control (I am using another method to scroll it as the program is designed to run on a touch-screen PC and the default scroll bars are to small to use).

I don't have a sure-shot answer for you, but I took a look at the CWnd class and noticed that it has a couple of functions you might wanna try: ShowScrollBar and EnableScrollBarCtrl.

Hello, I'm a beginner programmer and I'd like some advice if possible.
I'm TRYING to make an application that displays a bitmap (a map) and then I want to put values on that map, values that I take from a file. This wasn't a problem till I knocked my head to screen resolution changes and screen-to-printer changes. Now this is where I want some advice. Can anyone please tell me some CDC methods to use for this ? I don't want the program made, just some advice to build upon.
How do I pDC->TextOut(100,100,"Value") without bothering about screen resolution changes and display-to-printer conversions. Do I have to take screen rect coord and then do smtg like this : pDC->TextOut(100*(screenreswidth/800),100*(screenresheight/600),"Value") after inputing the coords with the resolution of 800x600. Or, do I have to use SetMapMode(MM_....) and then the Device to Logical() method ? If that, can anyone explain the concept since i'm not english and It's a litte difficult to translate (conceptually) device to logical. An example perhaps ?
And then, the screen-to-printer conversion problem. Is it absolutely necessary to calculate the screen-to-printer scale and then x*scale and y*scale. If so, it's a lot of work to do cause I have to display values for over a hundred cities on the map.
What can I do ?
Thank you !

you wish to draw text on the bitmap right??? You can try CMemBm class in codeproject.
|
|
|
|
|
No, I dont't wanna draw on the bitmap, I wanna TextOut some values and I needed advice for coordinates transformation which I can't get so easy.
The CMemBm class, from what I've seen it's just for drawing, so it's not helpfull.

Open the Quick watch window and in the edit box enter the function name (i.e. myfunc (0) ). Most likely will not work.

This is my third post now, can't anyone help me? I would like to know how to close/open a DeskBand from another process. Also why does explorer hang on to your deskband when it is closed? Am I doing something wrong? When I close my deskband, I can't delete the dll because explorer keeps it open.
If you know anything about this please help.
Thanks

The reason why IE is holding on to your DLL is because you have not properly destroyed all of your COM objects. There is a reference count in the object server of your DLL that keeps track of how many objects that are still active. And there is a function call DLLCanUnloadNow that lets OLE know if it can unload your DLL. This function will not let the owner process unload the DLL as long as there are outstanding objects.

Thanks, I knew this, but the other posts have confirmed my fears.

Explorer hangs onto the DLL whether the bar is actually open or not; you'll need to kill explorer.exe (or log off) to modify the DLL. I seem to remember hearing about a way to disable this, but can't bring it to mind right now... maybe TweakUI?
That's the extent of my knowlege; there are several articles on the subject here though; do a search for "explorer bar" and see what comes up.

IIRC it's the AlwaysUnloadDLL registry key.
|
|
|
|
|
I couldn't find this key I'll have to look further for the location. Although its a start, it's not the solution I want, I guess I can't change how they implemented it so I'll just have my install reboot the machine when updating.

Thank you for replying. I was afraid someone was going to tell me this. I don't understand why they do this other than as an optimization. It doesn't save that much time and they are just using more memory.

Does anyone have a list of CP web services - you know, the CP URLs ending in ".xml"? I could've sworn I saw at least one reference (the last "n" posted articles service), but it was 4am and I was fading. I didn't save the link and am now kicking myself.
Thanks,
