I guess you can. As long as you provide a way to inform your application's user about what the hell is happening i.e. why is it taking too long. are you getting my point? (Ofcourse, I am talking about interactive applications)

Yes I understand your point but what I am not sure about is if the dialog box's controls will still be accessible while the disk drive parsing is running. I mean, the question now is whether or not the dialog box will not freeze (if the message proc will still handle messages from the dialog box) ?

Do I really have to?
Thanks a lot for your replies and for taking the time.

i have two questions:
1) how do i go about creating a gui for a dos (not dos-mode) application? ie. what program do i use to creat this?
2) if i don't want to make a gui then what do i need to make a command based application in dos? and are .exe and .com the same thing?
thanks,
Rob Tomson

1) DOS has not a gui support, you need a third party library like Borland's Turbo Vision (text mode windows) or other.
2) All reasonable programing tools (Turbo Pascal, C/C++) for dos can create command-line programs.

i know dos doesn't have a gui support....so how do i make one? ex. i've seen some bios screens that have a gui.
i made a console app in c# but i guess it won't run in dos. can i make a console app in c++ .net or c++ 6.0?
thanks,
Rob Tomson

certainly ,you can make a console app in c++ 6.0.and you can make a gui like some bios screens .In visual c++ 6.0 you can't use windows classes like CWnd .

Hi all, 
In a dialog, is it possible to align a control with layout guidelines such that if the dialog is resized, the conrol is also resized accordingly?

Hi there,
I am writing an application where I want to open a file... but not via CWinapp:OnOpenFile(), I do my own DoPromptFileName().
My problem now (maybe very simple): How do I tell the OpenFileDialog, IN WHICH DIRECTORY it should start?
Example:
I got two different file-types to handle, one "*.abc" and the other "*.def". I also got two buttons, A = "Open ABC-file" and B = "Open DEF-file".
Now I have two default folders, maybe "C:\files\abc\" and "E:\Files\def\" where the files lay.
Now how do I tell the OpenFileDlg to initially browse in the "C:\files\abc\"-folder when pressing Button A, but browsing folder "E:\Files\def" when pressing button B?
I hope everyone understood my problem and anyone out there can help me...
Thanks in advance!

thanks for your help, but that wasn't it...
my situation:
I handle videofiles and they are in C:\video\. I opened one from there some time befor and now I want to open another video from a location I want to set beforehand. so I tried this (just for testing):
<br />
CString newName = "";<br />
if(SetCurrentDirectory("D:\\"))<br />
AfxMessageBox("yep");<br />
else<br />
AfxMessageBox("nope");<br />
<br />
DoPromptFileNames(newName, AFX_IDS_OPENFILE,OFN_HIDEREADONLY | OFN_FILEMUSTEXIST , TRUE, NULL, "MPG-Video", "mpg");<br />
The message I got was (surprise, surprise) "yep", so I thought, OpenFileDialog would browse "D:\" but - pow! - it went straight to "C:\videos\"...
any other idea ?
Thanx!

Unfortunately, setting the current directory won't work because Windows stores default dirs for the file open dialog in the registry (on a per extension basis).
You can make the standard Open/Save File dialogs use a custom initial directory by setting the lpstrInitialDir member of the dialog's OPENFILENAME struct. See this MSDN link[^] for details.

Does anyone know of an API that will return the localized descriptive name of a language, given its language id? Eg: ZH_CN = "Simplified Chinese", ZH_TW = "Traditional Chinese", etc.
Or is this information stashed somewhere in the registry?
Thanks,

I think GetLocaleInfo() is what you are after, but am not sure where ZH_CN and ZH_TW come from. From where are you obtaining these values?

Thanks, David! GetLocaleInfo() is exactly what I need!
ZH_CN and ZH_TW are variants (simplified and traditional) of the Chinese language. The MAKELANGID[^] macro allows you to specify primary and secondary (i.e. the variant) keys in order to create the locale passed to GetLocaleInfo(). Thanks again!

Top of the mornin' to ya!
Right then - using Visio OCX in a dlg app. Need to take soeme CAD drawings (dwg format), convert them to visio fmt and add to a custom stencil sheet.
Am using the following process(PSEUDOCODE obviously!)
<br />
GetAddon("Convert CAD Drawings...")<br />
Run<br />
<br />
Select all on page<br />
<br />
Drop to Stencil<br />
Only prob is that when I run the function a second time, the add-on converts a different dwg (since time take for converison varies wildly), but the object that appears in the stencil is the same as the one converted the first time.
Have tried to do a selection.delete, but on the second pass, visio reports that "the requested operation is currently disabled"...
Can supply full source if anyone can help - but can someone PLEASE stop me banging my head aginst this one!!!

Where are/were you doing the selection delete?
I'd do it after the drop, or before the first select.
Is any of this done asynchronously? That would leave the selection object locked during the 'drop', for example. I don't have Visio on any of my machines right now, and at the risk of seeming unhelpful, I'm not about to install it to try this at home  Hey, I have a life somewhere, I'm sure...
At the risk of sounding fatuous, have you tried this in VB code? It might be, for instance, that you have a lingering interface that you don't need, or something similar that VB manages. If it works there, your problem is your code, not the way it works (but you've heard me say that before...)

Ah - the man himself!! Hope all is good sir!
Have managed to get it sorted now, but thanks for the advice anyway...
The history is that originally it was a VB app, but if it was run more than once under the debugger, it was crashing and taking the IDE down with it - and by run, I mean F5, do some stuff, stop the app, F5 again, try to do some stuff and BANG....
Tried various things up to and including service packs for VB, but to no avail, and since urgent, was forced to do a re-write....
In terms of what was going on with the selection, since I did a straight port from someone else's code, stuck with their algorithm..part of it was to save the imported document to temp.vsd. Unfortunately, the second time round the loop, it was not overwriting the file, so when setting the src for the control, it was using the (unchanged) same file. Got around it by using lots and lots of different files (you know me Steve - why use one file when can use dozens!)

That's why the C runtime includes the capability to create a uniquely named file (see mktemp). You did, I assume, have error-checking when opening the file the second (and subsequent) time, to be sure you really could write to it? (rhetorical).
Main thing is that it's sorted, and you know why. Nothing worse than a problem that wriggles away, leaving you with a nagging 'what if it comes back?' feeling...

I am having trouble doing this program.
write a simple menu-driven program to allow a user to request a record by KEY. You should search (read) the file for the record, and display it if it exists in your file. A user can delete a record. If it exists, you need to add its vacated block location to the free list. A user can add a new record. if it does not exist, you will take a free block from the free list, and place the record there. Be sure to update all "next record" and "previous record" pointers on all add and delete operations. A user can update a record. if the record existsall you need to do is to allow the user to enter a new field value, then write the record back to the file. Finally, you should allow the user to display the file to screen as well as write it to a text file (not a binary file).
THe record can be a couple of fixed-length strings and an ID field, say an integer. To maintain both record blocks and empty blocks, each physcal record will have a pointer (really a file offset) to the next physical block and the previous one. In a sense this will be similar to a linked list - but it will exist in a file, not in memory.
Make data set large, at least 10,000 records. Gather data randomly or get a large data file from the internet. The exact data is up to you, but you should have int class an integer key value, plus at least two other fields. At least one of them should be a string (use a C-style string which is fixed length, to allow for easy random access binary file movement with seekg() or seekp().

I am having trouble with th eentire program, it would be great if u can run me thru the whole program. firstly I need to generate a free list using seek(). I think it would be easy if u can explaing me how to do the entire program.
