For this you have to use the office automation i.e using the some of the tlb files of office u can use the functions that the software provides.

here if u see the power point provides a tool called as "Save As" which gives u the facility to convert the .ppt into the jpg file
just u hav to u that tool and then u r on the way

Saving a PPT file as a JPG file will go something like:

CString strFileName = "abc.ppt";
_Application app;
_Presentation pres;
COleVariant vtFalse((short) FALSE),
            vtOptional((long) DISP_E_PARAMNOTFOUND, VT_ERROR), 
            vtJpg((short) 17);
 
if (app.CreateDispatch("PowerPoint.Application") == TRUE)
{
    pres = presentations.Open(COleVariant(strFileName), vtOptional, vtOptional, vtOptional);
 
    strFileName.Replace(".ppt", ".jpg");
 
    pres.SaveAs(COleVariant(strFileName), vtJpg, vtOptional);
 
    docs.Close(vtFalse, vtOptional, vtOptional);
 
    app.Quit(vtOptional, vtOptional, vtOptional);
}

hai all,

could you please give me the code , how to scroll the flexgrid.

just consider , if the flexgrid having 20 rows. at present only 10 rows are visible due to small dimensional flexgrid.

if i want to highlight the 20th row , it is highlighting, but i can't able to see it.
because 20th row is in the invisible portion of the flexgrid.
so how to auto scroll the flexgrid to see the 20th (highlighted row)

thanks
panthal

hai,
here i have some clue.
to achieve your task, follow these steps.
1. in pretranslate message, write the following code.
if(pMSg->hwnd==m_grid.m_hWnd)
{
if(pMsg->message==161)
{
int debug=0;//now put a break point here and debug the application.
}
}
2.run it in debug mode, and click the down portion of the dialog(i.e. for down scroll)
now you will be taken to the code as specified in point 1.
3.now see the values of pmsg->wparam and lparam say for example x and y.
4.now, in the place, where you want to automatically scroll your grid,
use the following code to scroll 1 cell.
m_grid.SendMessage(161,x,y);
i hope this logic is a bit confusing. but i tried it and it works.
if you could understand the above, then this should work for you too.
any more doubts, you are welcome.

--------------------------------------------
Suggestion to the members:
Please prefix your main thread subject with [SOLVED] if it is solved.
thanks.

Hi Friends,

I created a Dialog based application.To that i added flexgrid control.
I made it flexible so that it should keep growing as & when i add some data(some numbers) to it. After 10 records the grid grows & scroll wil be added.
But the problem is that, data after 10th ie:11,12...goes down.To see that i have scroll down.
I want it to display the current data.. For eg: for 15th record it should show the 15th one.

Please anyone help me out..
Thanks in advance.

It will be better if you create an object that contains a list of other object, and this object contains a list of ....

Take a look on my article http://www.codeproject.com/cpp/SmartListII.asp[^] specially on the comments I wrote at bottom. I explain a hierarchie that I used in my project. It may help you.

I havent done it for CList but I have for CArray, I have an array that is declared as follows in my CMyDoc:

CArray<CArray<CString, CString&>, CArray<CString, CString&>&> m_collections;

it is not the easiest of things to use, whereas

class CImage
{
}

class CImages
{
CArray<CImage, CImage&> m_images;
}

class CMyDoc
{
CArray<CImages, CImages&> m_images_images;
}

is much easier to use and read.

Hi,

I look in the setting some C++ project that i wrote using visual 2005 and i see some section
"Manifest tools".
What is Manifest in C++ project ?

Second question - what is the effect of set "Embed Manifest" to be "No" ?

Thanks for the help.

A manifest file describes the dependencies of your application. It is now mandatory (with VC2005) to use a manifest file. You will need to distribute it along with your application.

Yanshof wrote:

You can choose to embedd the manifest into the output file or created as a stand-alone file. If you choose the second option (stand-alone file), you will need to distribute it with your application.
