Hi,
I am just about to finish my application (I could at last make the dlls work together). But now I want to take a look in some issues that I didn't take care about before.
My program saves and uses files with extensions *.fs and *.pc, I have no problem opening the files from my app, but if I go to the windows explorer and want to open them outside my programm... I must Shift+Right click to say open with... and look or my app in the selection dialog box.
I have make it automatic (to my laptop) from the options of the windows explorer in "Files Type" property sheet, but I would like to have it for all computers.
I know there is a way to do it automatically, but I dont exactly know how... (I guess through registry)
I was thinking to compile all release versions (app, dll...) and take them with the third party dll, the inis, all necessary things... and make an self-extractor exe. But i would like to have the file association.
Is an installator needed? Can I code it into my programm (i.e. on InitInstance, so the first time it is executed check if the association exists and if not, do it)?
Which APIs, Functions, registry paths (if needed) should I look for info about?
Greetings.

ExtractIcon()? Please explain how this helps.

I am sorry, I have never used ExtractIcon().
However, For file icon association please follow below steps. Hope this will work for you.
1. Create '.YourExt' entry in registry under HKEY_CLASSES_ROOT.
Key = .YourExt
Value = YourAppName.
2. Create 'YourAppName' entry under HKEY_CLASSES_ROOT
Key = YourAppName
Value = Your Application
3. Create 'DefaultIcon' entry under 'YourAppName'
Key = DefaultIcon
Value = YourResourceDLLOrEXE_WhereverYourIconResides,-YOUR_ICON_ID
4. Create Shell\Open\Command key under 'YourAppName'
Key = Shell\Open\Command
Value = YourApp.exe
Regards,
Paresh.

I never said you did. I did, however, call into question your suggestion of using such. Double-clicking a file in Windows Explorer and have it associated with a particular application has nothing to do with icons.

You need to make the following changes to your registry:
HKCR\.fs = Nelek.Document
HKCR\Nelek.Document\shell\open\command = NELEK.EXE %1
HKCR\Nelek.Document\shell\open\ddeexec = [open("%1")]
HKCR\Nelek.Document\shell\open\ddeexec\application = NELEK
HKCR\Nelek.Document = Nelek Document

Thanks David,
I will try it as soon as I solve another thing that has come today.

I used GdiGetBatchLimit in my program, it returns 20.
Does it mean 20 proper functions (which return BOOL) will be queued?
But test shows that functions like Rectangel, Ellipse, etc are not queued, and take effect immediately. Why?

How to modify private member variable of any class without using member function???
Is it possible? If Yes, How???
ThankXXXXXXXXXxx
|
|
|
|
|
 You mean, from an external class ? What would be the use of private, protected and public keywords then ?
What are you trying to do ?
|
|
|
|
|
Thanks for your kind reply.
Ya then there is no meaning of private access specifier but i heard abt it that though it is violation of object oriented concepts but still it is possible in C++ using pointers.
I am not trying to do anything great but just trying it out and i believe it is possible.

If that class declares your function or class as a friend, then you can access.
I think you are asking not for that. If so you just cast the class object to BYTE* and you can access the memory. Or, if you are aware the class structure then you can create a dummy class with all the member variables as public and can cast the actual object to that of this dummy class. Thus you can access the members.

Ya i got it, without using friend function,i did it..

Have a nice crack day...

It may be compiler dependent, however, you can calculate the memeber address first, and access it directly (not through the object, do something like writing memory).;)

ThankXXXXXXXXXXx
Yes..i do not know it is compiler dependent or not,but using ur second suggestion it is possible..
ThankXXXXXXXXx a lot.

Here is a dirty trick to do so:
class ClassProtected
{
private:
int m_One;
UINT m_Two;
int m_Three;
};
class ClassPublic
{
public:
int m_One;
UINT m_Two;
int m_Three;
};
ClassProtected test;<br />
ClassPublic* pTest = (ClassPublic*) &test;<br />
pTest->m_One = 1;<br />
pTest->m_Two = 2;<br />
pTest->m_Three = 3;

I think it's a better way.

Usually, you souldn't.
Anyway, you can modify a class private member variable inside a friend function (or friend operator, or a method of a friend class ).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

In one of your workspace, you can add an existing project. I think this is the best way to do it. I cannot tell you exactly what you need to do (don't have VC6 installed) but try to go to the explorer view and right click on the workspace, you should be able to add an existing project.
Just start from one of the two workspace, and add the other project (dsp) to it. You then need to configure the project properties (of both projects) so that the output folder is the same for both of them.
