Hi all,
This is my constructor:
CUpdateServiceModule::CUpdateServiceModule()
{
m_status.dwControlsAccepted |= SERVICE_ACCEPT_PAUSE_CONTINUE;
m_bIsRunning = FALSE;
m_bIsPaused = FALSE;
MessageBox(NULL, L"Contructor",NULL, NULL);
}
I am wondering why the message box constructor appears when ever I rebuild my project, install the project and uninstall the project. Can anyone tell me why is that or what information do you guys need to know that?
Thanks,
jayjay

because the constructor function of CUpdateServiceModule() will be called by the com register.

even during uninstall and building?

When building your project, VC will register the component at the end of the compilation, thus the message box is shown.
And I guess an instance of that class is created when the component is unregistered (during an uninstall).

register and unregserver message during uninstall and building.

Be careful with the m_status.dwControlsAccepted.
The way the statement is written it will most likely contain garbage data when you build for release, unless it's initialized in some base class of CUpdateServiceModule.
Consider changing to
m_status.dwControlsAccepted = SERVICE_ACCEPT_PAUSE_CONTINUE;

I get similiar other warnings such as
warning C4996: 'strcat' was declared deprecated
warning C4996: 'fopen' was declared deprecated
warning C4996: 'itoa' was declared deprecated
why and when do these warnings arise ?
How to overcome them?
- thanks..

Because Microsoft introduced more secure versions of these functions. So either follow the advice given in the warning message (use the more secure version, like strcat_s) or disable the warning 4996 (you can specify that in the project options).

* You may suppress all the compiler warnings using /w option.
or
* Use /wd to supress a specific warning. Eg. /wd4996 will disable the compiler warning with ID 4996.

You can play with files in MFC using CFile class. Below shown code snippet will be of little help:
CFile cf_object;
cf_object.Open( "c:\\CP\\CP_test.txt", CFile::modeCreate|CFile::modeWrite);
char szText[100];
strcpy(szText, "File Write Test");
cf_object.Write (szText,100);

Rane

These guys are fast. Let me add up something that has not been said yet:
You can open the port to which the printer is attached (usually LPT1) as a file (just pass LPT1 as the file name to the function which opens or creates the file). You can then just write text to this opened file, and you'll see the printer is printing it out. If you consult with the printer documentation, it must have some specific ASCII command patterns (known as EPSON ESC CODE sequences), which you could follow to get formatted output, such as a receipt.

What does the link have to do with your question  ?
Anyway, there's no easy way to convert a MDI application to dialog based application. You need to restart a new project and copy/paste the classes and code you need. Of course, this is probably more complicated than that because the structure of the project changes completely.

Ok Can i show MDI out put on Dailog Application?
|
|
|
|
|
What do you mean ? If you want to put your MDI app contained on your dialog, that's not possible. Think a bit about it: you can have multiple documents open at the same time, how would do you put that on one single dialog ?
No, the best way to go is to completely rewrite your application and reuse part of the code. Otherwise this will be a complete mess.
|
|
|
|
|
ok can you give me some example how can i stat to rewrite application..
Plz help me
|
|
|
|
|
Not really no, because it completely depends on what you want to implement. The only advice I can give you is to create an empty dialog based application and then to add features little by little.
But converting from a MDI application to a dialog based application seems a very awkward choice, because the structure of your program and the way the user interacts with it are completely different. Are you sure you want to do such a thing ? What's the reason behind that choice ?

yes i want to change.Sir i have past here one link which is given information of current copy information and i want to do this in dailog based application,so i want to convert it.
Simply it is a programm of Clipboard viewer.And i search and ask question about it.But i havn't found solution.Now i am geting link from code guru and i want to change this application.
So plz help me

So, just because the guy use a dialog based application in his example, you are ready to throw out your existing MDI application and restart everything from scratch ? Sounds a very bad design decision, because as I said, MDI and dialog application are targeted for different usages.

SO in which way i go..Can you give me guid in which i go to do thatt?
Plz help me
|
|

|

Well, I don't even know what you are trying to do...
Anyway, the best advice I can give you is to read a good book about MFC, it seems that you are missing some fundamuntal concepts with MFC. A lot of people suggested this bool[^], never read it myself though.
