You can do this by ON_COMMAND messaging. ON_COMMAND messaging sends or pumps a message to your entire program. It gets very tricky when sending messages from one Dialog class to another. The best programming with respect to Dialog based programs, is to keep your Views ( Dialog ) loosely coupled from the inner workings ( Control ). Some go on the idea of MVC ( model, View, Control ) idea. Try to read up on this. Another way is to implement a GoF concept, by using the "Observer pattern" ( plenty of example here in codeproject ). This pattern does the job of keeping the Dialog class loosly coupled, and is continually updated when information is changed, or an action has taken place ( hint: such as a radio button clicked ). All in all, messaging from one dialog to another has its pitfalls.

I have created a view which need to be printed
by a printer , The base class for the view is
the CScrollView.
How can i print all the data, i also want to
ensure that if data is long enought not to
fit on one page then there should be some
blank space left at the starting and ending
of every page.

i made adialog based app and

would u tell me what will cause such a problem
thx

We can't answer this, by telling us what you want to happen, you're telling us what the code should do. You need to post some code so we can see why it's not doing that.
One possibility is that you're not cleaning GDI resources, and you're running out.

oh i havent access to code right now
when i use LoadBitmap() do i have to clean it or something??
i also releaseDC() the DC. do i have to delete memDC??
and i have another question. i have a Draw() func. i call it in onTimer()
is it acceptable? or i should call Draw() in onPaint()?
|

You need to release everything explicitly.
Yes, you should be calling Draw from OnPaint and calling Invalidate.

I want to get a list of system created folders like C:\windows, C:\Program Files, etc.
1. Are these the only two the system creates, or are there any more? how do we identify them all?
2. SHGetFolderPath with CSIDL_PROGRAM_FILES will give you only C:\Program Files, how do get the program files directory in other drives like D:?
|
|
|
|
|
if you have many 'Program files' folders in several hard disks, only one is owned by the system (because the other have been made by you - or a user). so, if the system is installed on C:, ShGetFolderPath() will return only that one...
understand ?

actually, thats my question too. Does the system own the Program Files folder? I thought it is the applications that get installed create this folder, and you can chose to install it in D:\Program Files. And the system installation also installs a few applications, thats why that folder will be there.
Anyways, C:\Windows, C:\Program Files and C:\Documents and Settings are the only ones the system creates, right? can any user's home directory be configured on a different drive than the system drive?

yes, but it own only the one it created during its installation.

certainly ! right click on a "My Documents" icon (on the desktop for example) and see the change target into the target property tab...
but i don't know how to do this programmatically...

Hi,
I have to get the Fully qualified name of my machine. I am using the function gethostbyname, hostent -> h_name attibute for the fully qualified name.
My problem is,
I can modify the "Primary DNS Suffix" value of my machine. The function gethostbyname returns me "MyMachineName.Primary DNS Suffix Value", if the Primary DNS Suffix given is invalid also. All the other settings(eg. DNS Server) are perfect.
My Question is,
How can i get the Valid FQDN? Or i have to do something to validate it?
Thanks

help needed
Thanking you all.

If it is to maximize the dialog, you can use ShowWindow(SW_MAXIMIZE);

To set the Dialog Box size at Runtime you can use MoveWindow or SetWindowPos Api's

For instance, RGB(255,0,0), how can I display it in different luminance?
Thanks.
|

When you do, it won't be 255, 0, 0. You need to convert to HSL, increase the luminance, then go back to RGB.

Hi friends,
Can anyone suggest tips or tools or tutorials for improve perfomance for old Visual C++ projects ?
My company maintains a lot of Visual C++ projects of our customers. Our customer gives C++ projects of about 2-5 years old and request us to improve perfomance.
If anyone worked for such kind of maintanence projects which includes perfomance tuning, please help us by your valuable tips. 
Thanks & Regards,
Jijo.

I offer this tongue-in-cheek:
When you initially create a project, lace it with gratuitous sleep and delay-type code. Then when the customer asks that its performance be increased, simply remove the extraneous code and voila...you delivered a faster product and the customer thinks you killed a bear!

It's hard to point to general techniques to improve performance in abstract.
As vague as it sounds, I'd say you first need to identify which are the parts of the program in which you find it slow to respond, and then visually inspect the code and make some profiling, looking for opportunities to improve.
Maybe if you posted about some concrete thing you want to optimize...

Dear Lamas,
Thank you for your reply. Actually that project is a mission critical backend application running in an ultrasound scanner product. Its build up on some alreay running frameworks. It uses a custom database. So no hope in optimizing those areas.
But the application is performing some communication by using winsock. So if you can comment on network communication optimization it will be helpful for me.
Regards,
Jijo.
