hi

i have one sheet with cca 20 cols, and first is a pic col. Everything works fine until i have over 70 rows and images, after some redrawing program randomly crashes.  After i remove picture cell everything works fine despite the number of rows. I work with unicode spread.

Error that i get in release is:

  Fault Module Name:    FPSPRU80.ocx
  Fault Module Version:    8.0.0.7
  Fault Module Timestamp:    4a01eb0e
  Exception Code:    c0000005
  Exception Offset:    0008c0d3
  OS Version:    6.0.6002.2.2.0.256.6
  Locale ID:    1050

 In debug it crashes in:

 vctools\vc7libs\ship\atlmfc\include\afxwin1.inl Line:893

 

 Picture is dynamicaly added every time spread refresh with this function:

void SetPicInCell(CSpreadSheet* m_Spread, UINT IDB_PICTURE, long lRow, long lCol, BOOL bTypePictCenter /*= FALSE*/, BOOL bTypePictMaintainScale /*= FALSE*/, BOOL bTypePictStretch /*= FALSE*/, int nTypeValign /*= 1*/)
{
    CPictureHolder picture;
    picture.CreateFromBitmap(IDB_PICTURE);
    if(picture.GetPictureDispatch() == NULL)
        return;

    m_Spread->SetRow(lRow);
    m_Spread->SetRow2(lRow);
    m_Spread->SetCol(lCol);
    m_Spread->SetCol2(lCol);
    m_Spread->SetBlockMode(TRUE);
    m_Spread->SetTypePictCenter(bTypePictCenter);
    m_Spread->SetTypePictMaintainScale(bTypePictMaintainScale);
    m_Spread->SetTypePictStretch(bTypePictStretch);
    m_Spread->SetTypeVAlign(nTypeValign);
    m_Spread->SetTypePictPicture(picture.GetPictureDispatch());
    m_Spread->SetBlockMode(FALSE);
}

 Is there a problem in spread or in my function.

Thank you.

Hello,

I am not sure what is the reason you are not able set the PictureCellType on the Fly.

Below is the code that I used to create a PictureCellType and added a picture on a Button Click,

Private Sub Command1_Click()
     fpSpread1.BlockMode = True
     fpSpread1.Row = 1
     fpSpread1.Col = 1
     fpSpread1.Row2 = 100
     fpSpread1.Col2 = 2
     fpSpread1.CellType = CellTypePic
     fpSpread1.TypePictCenter = True
     fpSpread1.TypePictMaintainScale = True
     fpSpread1.TypePictStretch = True
     fpSpread1.TypeVAlign = TypeVAlignCenter
     fpSpread1.TypePictPicture = fpSpread1.LoadPicture("D:\ImagesIcon\png\folder .png", PictureTypePNG)
     fpSpread1.BlockMode = False
End Sub

Please post a small zipped application for us to debug if the issue still persists.

Thanks,

Hi, here is a small test project: http://rapidshare.com/files/301342674/TestSpread.rar

 

1. Problem with pic cells...

Just click on Start TEST2 and program will start to ClearRange and fill 500 rows of spread 20 times. Then click again on the same button and if you try to move dialog you will see that something is wrong... after some mouse moves or clicks program crashes...

 

 2. UNICODE problem

In same project I noticed one spread Unicode problem.

You need to start program again. You will see two col, one is empty, second have some cyrilic. When you double click on it it will open a combo box but there is a problem with text in it. Strange marks are shown instead of text...

I realized if I go to dialog properties and click on spread properties and change font from default Microsoft Sans Serif to for example Microsoft JhengHei and then return font back to default Microsoft Sans Serif. When you start application again everything works fine, there is no strange marks... if you delete spread and insert new and start application you will have problem again... So my question is is there some error with setting up default font on Unicode spread? I have more then 200 spreads in my app and if i need to change manually font back and forward... it will take me a lot of time :(

Hello,

I am not able to download the project from  http://rapidshare.com/files/301342674/TestSpread.rar.

You may email your project to fpsupport@fpoint.com along with the link of this Thread.

Thanks,

Hi,

There is a problem in your code (it leaks memory) -- calling picture.GetPictureDispatch() will add a reference to the IPicture object which must be released in your code.  You need to add a call to picture.m_pPict->Release() after the check for NULL and the return.  Spread will release the reference passed into SetTypePictPicture.

I added release code but there is still a problem... I sended project to mail

I have looked at it further, and it appears that change I suggested is not sufficient.

Your code is exhausting the resource handles by creating too many separate Picture objects.

If you change your code to reduce the number of Picture objects created to the minimum number, then the problem should not happen.

I suggest adding LPPICTUREDISP fields to your class and initializing them in the constructor with CPictureHolder objects the way you are in your helper function, but just once for each picture.  Then you can call Release on these objects in a destructor for your dialog class, and use those objects to pass into the SetPicInCell code instead of UINT.  Then there will only be four Picture objects created and reused in the cells, rather than many copies of the same image which each use a different HBITMAP.

I have been looking into the other issue with the font for the combo box list, and it seems to work when I add this line of code at the top of the FormatSpread() function:

  m_Spread.SetFontName(_T("MS Shell Dlg"));

For first issue I changed code as you suggested and now all works fine. For second, ok, i will do that or just change font forward and backward on properties, same result. But i posted it to inform you that maybe something is not working 100% right so you can check it for further releases.

Thank you for your time. Best regards.

 

Hi,

I will forward the issue to development for review.  It is strange that the text works in the combo edit box but not the list.  The list is supposed to use the same font.

Thanks for letting us know about this issue!
