add --> New item --> user control
What do you mean with combining two controls??
|
|
|
|
|
I want richtextbox to behave like a container so that i can add childcontrols to it.
|
|
|
|
|
just make a usercontrol
put the richtextbox and all the other controls on it
then you have your custom control

Have you *tried* to do a standard SQL SELECT query against the data using the relevant JOIN between on the columns in the two tables?

I am using VS.net 2005. I hv created reports using 2005 and crystal reportviewer for displaying reports. Report displays fine but it displays very slowly. I mean to say, for a normal rpt where there is no calc also it takes 3 to 4 mins to display. Whereas the display rate is fast as compared to client machine.
Any specific reason about it?
Solution will be highly appreciated.
Thanx

Does this always happen when opening a report or only the first time?
Reason for asking is that the first time you open a CR the runtime gets loaded and this takes some time (although 3min is very long), after that it should go fast.
Another reason might be your connection.

Is there a way to use data that is created from a combination of the current DataGridView cell and a math function carried out by vb, to enter the new adhoc data into the cell and refresh the datagridview to reflect this new data combination?

Most DGV are populated by binding them to an underlying list (List<t> or data table/view) you could add an extra column to the list and populate that column with the results of your function.
How are you populating your DGV.

Use the following code as a starting point ...
totalrows = ActiveSheet.UsedRange.Rows.Count
For i = 1 To totalrows
MsgBox(Sheets("Sheet1").Cells(i, 6))
Next i

You need to modify a little, the code snippet that David Mujica gave you
Something like that:
totalrows = ActiveSheet.UsedRange.Rows.Count
For i = 1 To totalrows
'MsgBox(Sheets("Sheet1").Cells(i, 6))
Sheets("Sheet2").Cells(i, 6)=Sheets("Sheet1").Cells(i, 6)
'or whatever
Next i

please tel me how i can make four image with x,y resolution , from the input pic of x*2,y*2 image resolution , so if we consider the input image in four pixel squares (two pixel width and two pixe height) the first of output use the first left pixel of four pixel in the square and the second picture use the right top pixel , third use the bottom right, and the fourth use the left bottom ,
i use the setpixel and getpixel method for it, but it is too slow , i think if i use method of changing the image to array it will be very faster, please tel me ho i use the array method.
this is my code in vb.net but too slow :
For y = 0 To picy.Height - 1 Step 2
j = Int(y / 2)
For x = 0 To picy.Width - 1 Step 2
i = Int(x / 2)
pic(0).SetPixel(i, j, picy.GetPixel(x, y))
pic(1).SetPixel(i, j, picy.GetPixel(x + 1, y))
pic(2).SetPixel(i, j, picy.GetPixel(x + 1, y + 1))
pic(3).SetPixel(i, j, picy.GetPixel(x, y + 1))
Next x
Next y
best regards

Read my articles on image processing. You will need to use C#.

Hi,
if all you need the new image for is showing it on screen, you should not spend any time creating such image, just consider using a Graphics.DrawImage with InterpolationMode.NearestNeighbor
to get it completely correct you probably also have to perform a Graphics.Translate() over half a pixel in both x and y!

I'm not sure what his ultimate purpose is, but it looks like a pixelating viewer, maybe an editor.

this code used for generating four picture from input one, in half resolution of the source image.
this applied to print machines , in micromovement technology for decreasing the print resolution in the paper exposing of the digital printing machines.
it may be used in 9 from one or 16 from one picture.
