Hi Experts,
How can I pass a message from dll application to other application?
|
|
|
|

With PostMessage, of course.

What's a "dll application"?
We deal in "processes" here
Do you need to pass a message from one process to another?
If so... Interprocess Communications[^]

Hi all,
I am writing this code in VC 2005
TCHAR szPath[MAX_PATH];
CStdioFile sys_file_ptr;
GetModuleFileName(NULL,szPath, MAX_PATH);
PathRemoveFileSpec(szPath);
suppose file is located at this path
szPath = C:\New Folder\new.exe
and after using PathRemoveFileSpec() API i am getting this result
szPath = C:\New Folder
i want to add a slash at the end of the string. i do it using this code
szPath = szPath + _T('\\');
it gives error
error C2440: '=' : cannot convert from 'TCHAR *' to 'TCHAR [260]'
i have tried strcat()also but it also gives some error.
somebody can tell me how to do this......

use _tcscat() inplace of strcat, as you are using generic text data type.

You cannot do string concatenation that way with a character array. you must go on with a C-like approach:
_tcscat(szPath, _T("\\"));

Aside from that being syntactically wrong, why not just use PathAddBackslash()?

Hi everybody!
In a project I am working on I have a modal dialog and I would like to show an other modeless dialog by clicking on a button.
The modeless dialog is created before the DoModal is called, and therefore after clicking on the button (only ShowWindow(SW_SHOW) ) the modeless dialog it will appear, but I can't click on it, because it has no focus.
Have anybody an idea how can be solved this problem?
Thanks in forward.

that is the behavior of Modal Dialog, the user cannot interact with other windows until the dialog box is closed, then you have to go for Modeless dialog instead.

Why not create and show the modeless dialog after the button is clicked?

Because is too late to create after button click. I have to communicate with that dialog, it is alive (but not visible) durring the project run.

How can I have my application always in top
|
|
|
|
|
what about,
SetWindowPos(hWndApplication, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);

Or create window with WS_EX_TOPMOST extended style.
You can change position after window is created only using Rajkumar'a approach.

HI,
Iam a VC++ programmer having 3 years experiance.
Few of my friends telling that no new Project or Product starting using VC++, only maintenace products need VC++.
I want to know is there good future to vc++ ? or shall i need to migrate to .Net Technologies.
I hope there must be experianced People in this group please advice me.

IMHO the above is wrong. Anyway .NET (and Java) probably will grow their market share. You may have a look at recruiter agency websites (like Jobserve) to get a rough idea of C++ (against .NET languages) opportunities.

Thanks for your replies.
Iam intrested in VC++ and COM.
We are doing a product Using MFC and COM.
My Company dealing many projects in C# and Asp .
Presently one of our onsite Coordinator Also telling that there is lots of opportunities in .Net than VC++.
Our Product didnt get any strong Client to get good Revenue.
But All these .NET Projects are from good Clients.
All these issues, make me to think.
Bye,
Krishna.

Hi Krishna,
It is not a wrong thing if someone tells you that there are more opportunities with .NET than with MFC. But I won't agree if someone says MFC or Visual C++ has no future. I would suggest you to give .NET a try too. If that interests you, you could then easily decide which way to go. .NET have more opportunities, but to my mind, Visual C++ is more interesting. I think it is too personal and must be left to the individual to decide. Good luck.

The future of any programming languge is in the hands of developers like you. Keep using it and proving that you can produce great software with it in an economical time frame and it will continue to be valued and supported.

Stop worrying so much about which tool is going to be around longer, or has more followers, and focus more on what tool best solves the problem. Until you have laid out the problem in detail, you have no way of knowing which tool is best for the job.

Small business applications and in-house binary tools will most probably be dominated by .NET technologies as they generally require rapid development. However most major commercial applications will continue to be developed in C++ for the next several years.
Both C++ and MFC have a very secure future at least for the next 4-5 years in my opinion.
Best Wishes,

I don't agree completely. Rapid development has become a major requirement. I think that most commercial applications, included big ones, will be developed using .NET languages. Anyway, that doesn't mean C++ will be abandoned.
