Also Stuart, how do we access the Document from a Dialog that I added through "insert new dialog" in resource option?
|
|

|

Well, you would need to tell the dialog about the document. You could add a CDocument* member variable to the dialog and set it before you call DoModal.
Alternatively (and I prefer this one), just pass the relevant attributes of the document to the dialog, so the dialog doesn't need to know about the document - letting the dialog have visibility of the document class upsets my aesthetic sense.

Hi to all again,
Here is an another doubt of mine.
while creting an mfc application it ask "how would you like to use the mfc library" .And the options are
1. as a shared dll
2. as a static linked library
What does this actually means?What is the difference?Is there any relation between this option the exe size.
Thanks in advance
I am a beginner

It specifies how you will link to the MFC libraries:
- static linking, in which case, all the required MFC functionalities are imported into your application. Which makes the exe size larger.
- dynamic linking (dll), in which case you use a MFC dll which makes your exe size much smaller. The draw back is that you need to distribute the MFC dlls along your application (if they are not present on the target machine).
|
|

|

(probably bad explanation, I'm still not fully awake)
1. Will use the shared MFC dll : meaning that if you have 2 different MFC applications with this setting, they share the MFC code in the DLL; meaning the MFC code is NOT included INSIDE your application, making it size smaller. There are potential issues if there are different versions
of MFC dll installed (or not) on the target machines (refer to DLL hell), most of the time you will need to ship your application with the "redistributable" (sp?) DLLs, makeing the installation packages bigger.
2. static linked : ill include the MFC code INSIDE your application, making it fully independant and stand-alone, and should run on target machines without MFC installed; this will make the application bigger, but will remove most (if not all) external dependancies, and limit DLL hell.

I think someone explained you few hours before.[^]
When you statically link it. (just like you link an MFC runtime) This gets added to your executable. You will not have a dependency but the executable size becomes bigger. When you link dynamically, the dll is kept independent and your exe uses it everytime and hence the advantage. Any number of exes can share the same dll.

I am using spread controller in my code.(i am using farpoint7.0)
I have spread data like
This is header one1
Type | col1 | col2
-----------------------------
GroupA | 35 | 38
AA | 12 | 11
Bb | 12 | 13
cc | 11 | 14
when user right click on header GroupA row also getting sorted.
i don’t want to sort first row always how to do it ..please help me out…

please help me to draw a arc betwwen two lines without using windows API.
and then i have to find angle betwwen these lines.
this code is being written for a embedded project in VC 6 thats why i cant use windows APIs.
|
|
|
|

Your question is a bit vague. Which information do you have for each of the lines ?

 And how will you draw something if you can't use the windows API ? With your pen maybe ?
There is still a windows API even if you develop for an embedded platform.

Well, for instance, my mobile phone hasn't Windows API...

actually i am new in this field thats why i wrote as per my scope and thats why i am here to take help from you guys...
so details for first question-->
i have these three co-ordinates for these two lines.
these arc will be drawn basically to show angle measurement
and in this product there will be some RTOS thats why i wrote not to use windows API..i may be wrong in this context 
|

Are you afraid of giving details ?
vikas choudhry wrote: i have these three co-ordinates for these two lines.
Which 3 coordinates ? I guess (but it's just a guess) the coordinates of the intersection point, and of the two other end of the lines ? Are the two segments the same lenght ? If yes, that would help a lot because then you know that the center of the circle is the intersection point.
vikas choudhry wrote: and in this product there will be some RTOS thats why i wrote not to use windows API
You told us you were using VC6 . So, which platform are you targeting ? To draw something on the screen, you'll probably need to use OS specific functions.

If you have the coordinates of three mainingful points (for instance one of them must be the intersection between the lines ) then you may calculate the component of the vectors, take the dot product, divide by the vector modules and finally use the inverse cosine function to get the angle (well one of the two...).
As about drawing without APIs, I have a suggestion: [^].

1. Find the forumla to generate all the points[That makes up the arc] between given two points.
2. SetPixel() all those points.

What API could you use?

That's not difficult. Have you the equations of the two lines?

Oh, I by the way, as far as I know, VC6 supports only win32 platforms. At that time you had to use Embedded VC4 (or something like that).
|

|

(don't know the exact functions to call, but it should be simple enough to google for them)
( I wish I could draw something, it would make things easier to explain)
0. compute the angle between the first line to the X axis, compute the angle between the second line to the X axis;
1. find the intersection of the two lines; the intersection point will be the center of the arc (which is a section of a circle)
2. find a point on each lines that have the same distance from the center; this will be the radius.
3. Use the CDC::AngleArc ( or ::AngleArc) to draw the arc between the 2 angles. (i.e. from the first angle to the second angle).

can somebody provide me the sample code to draw a arc between two lines.
i have intersection point of these two lines and end points of these lines. now i have to use set pixel or any other standard vc++ function to draw it.
other way is to generate all point of a arc and then use set pixel but i dont know how to use it

Hi There.
I have a Win32 dll project, though I am successfully able to create dll file but there is no lib file created.
Please suggest, why this is so.
Thanks
Pankaj

You need to export at least one function in order to have a lib file which is created.

Thanks. You are right, I forgot to export my class.

Hello,
Does anybody know how to move horizontal pagebreak in excel through VC++ code?? I want to drag the first default horizontal pagebreak to new location.
Following is the code snippet..
HPageBreaks xlPageBreaks = m_xlSheet.GetHPageBreaks();
HPageBreak hb = xlPageBreaks.Get_Default(1);
COleVariant vCellTo = cellAt( 1, 62 ); // move pgebrk to this location
Range rangeDest = m_xlSheet.GetRange( vCellTo, vCellTo );
hb.SetRefLocation( rangeDest ) //
The method SetRefLocation() throws an exception.
Thanks,
Daryappa.
