Mine did too for quite a while. Out of the blue, however, it would revert back to its original size.
This is also an issue with VS6. I guess ~10 years is not enough time to get it fixed!

David,
How do you know it is a bug? Considering that you have declared a static control as LTEXT (left aligned text) it makes perfect sense for the IDE to resize it so it will correctly draw the default system font. I would suggest that you try changing from LTEXT to CONTROL with the SS_ETCHEDHORZ property set. If you are not comfortable modifying the .rc file directly... from the toolbox in the IDE this is actually "Picture Control" with the "Etched Horz" set to true.
If after making this change you see the same behavior then I would agree that it is a bug.
Best Wishes,

The IDE should never make such an assumption. If I want a control to be a certain size, so be it. I can make edit controls too small all day long and assign a huge font to them, all without the IDE's or Windows' interference.
If the IDE was trying to be helpful, why would it not resize a static control that is 8 DLUs high with the SS_SUNKEN style? The default dialog font will not fit in such a control without the bottom of the text getting cropped. You have to make the control 1-2 DLUs taller.

I put the change in place. It may take a bit for the problem to surface, if at all.

Hi David,
Well I have never seen anyone attempt to use a static control in such a way. A single pixel is not even enough room to draw the LTEXT SS_SUNKEN static control. I suspect that the IDE is attempting to do something intelligent and the result is failing to meet your expectations. If you believe that this is a bug then I would suggest that you report it over at http://connect.microsoft.com/VisualStudio[^] and perhaps one of the guys on the Visual Studio team will explain the logic behind it.
The sunken border effect that you were looking to achieve should probably be done with the CONTROL static with the SS_ETCHEDHORZ set. Now that you have made this change I suspect that the problem you were having will go away. Please update the forum thread if the problem reappears.
Best Wishes,
-David Delaune

That's the way I learned how to do it way back in the early 90s (with Petzold's book). Old habits are hard to break. Back then MS did not have a resource editor. I routinely used Notepad, and then started using the one from Borland.

Hi David,
It sounds like we are around the same age. I was also programming with C/C++ back in the mid 80's and early 90's.
DavidCrow wrote: Back then MS did not have a resource editor.
Sure they did. The resource editor back then was called 'App Studio'. I still have my copy of Visual Studio 1.0 and I also have installed in a VM image. I made a screenshot of the resource editor for you.

I was mostly doing Unix (SunOS) development back then... the closest thing we had to notepad was pico (although most Unix C/C++ software engineers used emacs/vim). I moved permanently to Linux development around 1994/1995. Windows programming was only a hobby born out of curiosity at that time. I did not begin doing full-time Windows development until around 1999/2000 soon after RedHat bailed out of desktop development when they had a dispute with the Gnome developers.

I had a similar behaviour with the VS 2003 resource editor some years ago:
Whenever I changed something in a dialog using the resource editor, the style of a datetime control set to the time picker format changed to the date format. The DTS_TIMEFORMAT mask was removed while the DTS_UPDOWN mask was still present.
Finally, I hard coded the style in the PreCreateWindow override of my already existing CDateTimeCtrl derived time picker class.

Hi Everyone.
Not sure if anyone met this situation.
I have a program (client) sitting one one computer (WinXP) and a server sitting on another computer (win7). My programs works fine and will not crash when the ethernet cable is pulled out, when the server program is shutdown etc. BUT when the server computer turns off, the client program will crash when trying to connect (it will try to connect to a server every 3 seconds). If the computer is on and even if the server program is not running, the client is fine and will just continue to connect. Not sure what is happening when a computer is off but the ethernet cable is still plugged in.
Has anyone seen this kind of thing? Is there something that I need to do or check for in the client that will prevent this crashing from occurring?
THanks !

The first thing I would do is to try some debugging to find out what is causing the crash; and what sort of crash it is. Is it a bug in the client code, something in the system libraries etc? Without that information it's not easy to suggest how to fix it.

How long does it take to crash?
As a wild guess...something to do with Active Directory and DNS resolution. Of the scenarios you listed I would suspect that on shutdown AD is told about the server shutdown. Where in the other cases AD doesn't know about it.
Consequently AD fails for the one case where in the others connectivity failures are the result.

That is a very small retry window. Presumably you are correctly cleaning up after each of those attempts.
|
|
|
|
|
For debug purposes... did you try to extend the retry (longer than 3 seconds)? Did you make sure the last attempt was finished, failed, and was cleaned up before you attempted to connect again?
3 seconds may not be enough time for the initial attempt to timeout... something to consider.

Hi All
Is that any simple way to transfer files from one computer to another computer via internet using VC++ code
|

Try googling TCP/IP
Why is common sense not common?

I am not sure about the transfer, but a way to get proper answers in CP is not reposting[^]

thanks for your reply but i need to sending and receiving data across a internet

That is exactly what sockets were designed for. Try a Google search and you will find plenty of samples and tutorials that will help you.

Okay but i tried many sample socket program it's works fine within a network ips like 127.0.0.1 but i tried to connect dynamic ip( which is get for www.whatismyip.com) it's fails to communicate..

To use IP there are two computers: client and server.
To use IP there MUST be a way to route between those two computers.
To route the address of the server must be exposed to the client. There are ONLY two ways to do that on the internet.
1. The server MUST have a public IP.
2. The server MUST have a network setup (routers/gateways) such that a public IP will route to the server (the server need not have a public IP.)
whatismyip will always give a result but that result doesn't mean anything. All that matters is 1/2 above.
For normal ISPs there are three ways that they provide customers with "internet".
1. The customer has a static public IP.
2. The customer has a dynamic public IP.
3. The customer does not have a public IP. (in this case it does not matter whether it is static/dynamic.)
The result of whatismyip is only relevant to the above if the ISP is 1 or 2. If that is the case then the IP listed is the one that your computer (or router/modem) has.
Note that 127.0.0.1 is not a public IP nor is it a private one for that matter. (Also just because your computer has a public IP it doesn't mean it is public on the internet but it does make it more likely.)

i have a problem, how to make a file transfer UDP client-server by giving 1 bit error in the file being sent?
|
|

|

Your question is a bit unspecific. What do you have trouble with? UDP? Using the parity bit thing? Reading a file? What did you try until now?
