Re: Problem in Exporting From Crystal Reports.

Hi
I think you need to type cast to Memory Stream from ReportDocument. See the sample code below for exporting from Crystal Report to PDF.

MemoryStream oStream; // using System.IO
rptDocument.SetDatabaseLogon(StrUID, StrPwd, StrServer, StrDatabase);
oStream = (MemoryStream)rptDocument.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);

Response.Clear();
Response.Buffer = true;
Response.ContentType = "application/pdf";
Response.BinaryWrite(oStream.ToArray());
Response.End();

I used Crystal Report 10 in VS2005.

it is actually cloning of controls.If i create new object and assign the properties of the copied control to the new object, then after pasting the Changes made in the copied control dialog is reflecting the change in also the pasted control dialog object.
in the above said way i assign the dialog object also directly.

If i use the this.memberwiseClone()to create new object the object is reflecting the dialog values.

i had write this code using c# to do drag and drop. But it just for drag and drop. i need it to reorder itself after the drag and drop. how can i fix this code to do the reorder?

private bool isDragging=false;
public int x,y;

private void panel1_MouseDown(System.Object sender,
System.Windows.Forms.MouseEventArgs e)
{

isDragging = true;
x = e.X;
y = e.Y;

}

private void panel1_MouseUp(System.Object sender,
System.Windows.Forms.MouseEventArgs e)
{
isDragging = false;
}

private void panel1_MouseMove(System.Object sender,
System.Windows.Forms.MouseEventArgs e)
{
if (isDragging == true)
{

panel1.Left = e.X + panel1.Left - x;
panel1.Top = e.Y + panel1.Top - y;

}

Anyone can help to solve the problem of:

In the web form, there are two datagrids that located at the top and bottom. After databinding,
the top datagrid may give no room for the bottom one because of too many data.
Any dynamic solution to move the bottom datagrid according to the top grid after-databinding-height.

Thanks

Hi I am developing a windows application in which it contains a grid and two buttons called play and delete.
If user selects a row on the grid and clicks play button then all the images are shown in a slideshow. (for showing slide show iam using a a new form which it contains a picturebox.)
if user selects a row on grid and clicks delete then it deletes the folder of images.

THe problem is when i select a row and clicks the play button it is showing the slide show. After exiting if i select the same row and clicks delete button then it is saying the picture X is used by another process.

How can I overcome this problem. Please Help me.

Thanks in Advance.

if images are being shown in the Grid. it means they are being used by another process.
firstly Remove that Row then those images

How to know that a point is inside an object or not?

Duong Tien Nam7-Mar-07 19:12

As far as I know, only Rectange(F) class has "Contains" method to indicate that a point is inside it or not.

Now I want to find the point inside an ellipse and other shape, is C# support it or we have to implement some argorithym to find out.

Thanks for your help.

hi
you can create a Region that describes your ellipse. the Region - object has a Contains (or something similar) function.
