A bit more exact would help, I mean a copy'n'paste of the real thing.
The error that's returned is usually caused by an automation failure. Probably due to the code doing something it's not allowed to do. What your doing by putting the formula in a range of cells is not what your code is doing.
I don't do Office Interop projects, so my experience is very limited.

With mObjExcel<br />
.CreateRange(.GetExcelColumnName(EnuColumn.UnitPrice + mIntColumnCountFactor) & mIntColRow(intCounter) & ":" & .GetExcelColumnName(EnuColumn.UnitPrice + mIntColumnCountFactor) & mIntColRow(intCounter), mStrSheetNames(intCounter))<br />
.CellRange.NumberFormat = "#.##0"<br />
.CellRange.Formula = "=SUM(" & strFormular & ")"<br />
.CellRange.BorderAround(Excel.XlLineStyle.xlContinuous, Excel.XlBorderWeight.xlMedium, , mObjBlack.ToInteger)<br />
End With
The "GetExcelColumnName" is a function which just returns the Excel Column name such as A1, B2 based on a column and row number. Nothing special - just one I made to help myself.
The strFormula variable is the formula mentioned which looks like 'Sheetname!Cell;Sheetname!Cell' and is build dynamically based on which actual sheetnames and cells are used.
The formula works when I copy it into the generated excel document so there is not a problem with the formula as such. Just the generation of it automatically
Inside my mObjExcel the CreateRange looks like
<br />
Friend Sub CreateRange(ByVal range As Object, ByVal strSheetName As String)<br />
SetCultureFixStart() ''Changes the current Culture to en-US, casue otherwise excel automation crashes<br />
If Not mObjCells Is Nothing Then ReleaseComObject(mObjCells)''cleans up COM objects which might linger in memory<br />
mObjCells = Nothing ''cleans up COM objects which might linger in memory<br />
System.GC.Collect() ''cleans up COM objects which might linger in memory<br />
mObjCells = mObjSheets(strSheetName).Range(range).Cells<br />
SetCultureFixEnd() ''sets culture back<br />
End Sub
And CellRange is just a property which returns my mObjCells (which is an Excel.Range).
What strikes me as most annoying is that the above code works when I use 1+1 in the formula instead of Sheetnames!cell, or when I post out more complex formulas, even .FormulaArray work.
So basically so far, I've been able to do all I wanted to, except use Sheetnames in a formula :/
Thanks so far for the feedback/time.

I've made a much more simple example which also fails:
mObjExcel = New Excel.Application
mObjWorkBooks = mObjExcel.Workbooks
mObjWorkBook = mObjWorkBooks.Add
mObjSheets = mObjWorkBook.Worksheets
If mObjSheets.Count > 0 Then
For i As Integer = mObjSheets.Count To 2 Step -1
mObjSheet = mObjSheets.Item(i)
mObjSheet.Delete()
Next
mObjSheet = mObjSheets.Item(1)
Else
mObjSheet = mObjSheets.Add
End If
mObjSheet.Name = "A"
mObjSheet.Range("A1").Value = "1"
mObjSheet = mObjSheets.Add()
mObjSheet.Name = "B"
mObjSheet.Range("A1").Value = "1"
mObjSheet.Range("A2").Formula = "=SUM(A1;A!A1)"
This fails, but if I substitute the formula for =SUM(1+1) it writes correct.
The formula is taken directly from what Excel wrote when I made the SUM in there.

I found a workaround which only confirms my suspecision that it must be something culture specific issue.
I could instead of using a SUM formula add the cells together - and I was able to do this with the sheetnames in the addition, so instead of "SUM" I use "=SheetName!Cell+SheetName!Cell ...." and that looks to work when printed out as a .Value.
Wheee. 
Thanks for the help otherwise

Hmmm...very weird. I wouldn't have thought that the culture would affect the sheetname.

I have no Excel automation experience, but maybe this idea could help:
you could enter the formula in Excel manually, then use automation to see how it looks...

The formula works, so that one is not a problem. I just can't generate the document automatically with this formula - but I can copy it into the document after generation where it would work.

I have a datagrid when i click on it at the starting of a row the whole row gets selected and the
datagrid.Columns(i).Text will give each column's text individually.
Even when i click on a perticular column of any row the text in that perticular column gets selected. can i get that perticular text at runtime.
i mean i want to get the text of the perticular cell(x,y) on which i click.

This code doesn't make sense because the DataGrid class (Windows Forms) doesn't have a Columns collection.
The ASP.NET DataGrid does have a Columns collection.
So which is it? The Windows Forms DataGrid or the ASP.NET (Web Forms) DataGrid in the .NET Framework 1.x (Visual Studio 2002 and 2003)?? Or are you really using the DataGridView class in the .NET 2.0 (Visual Studio 2005)?

Hi
I want to open a registry key for changing the owner , user has admin right
Dim User As String = Environment.UserDomainName & "\" & Environment.UserName
Dim K As Microsoft.Win32.RegistryKey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing", RegistryKeyPermissionCheck.Default, Security.AccessControl.RegistryRights.TakeOwnership)
Dim RS As Security.AccessControl.RegistrySecurity = K.GetAccessControl
Dim NTA As New Security.Principal.NTAccount(User)
RS.SetOwner(NTA)
K.SetAccessControl(RS)
But .NET throws an exception : Requested registry access is not allowed
I can open Regedit.exe and take registry key's owner ship , why this code doesn't work ?
|

You haven't opened the key with the appropriate access and permissions. You've opened it for Read, but not Write.
Try changing the OpenSubKey line to:
...LocalMachine.OpenSubKey("...", RegistryKeyPermissionCheck.ReadWriteSubTree, Security.AccessControl.RegistryRights.FullControl)

How can i invoke that javascript functions in vb .net?
I'm using windows forms, webbrowser control (AxInterop.SHDocVw.dll)
i m trying to automate the work once done by the user ( such as downloading or uploading the files ( the addresses are specified in a file by the user), navigate to the pages as by the user in the same manner )
i have maintain a list of webpages visited by the user by picking up the myhtmldocument.url
but i have no idea how to send and get the information sent as post method.

Hi guys,
I'm having some problem with this. I'm writing a small tool that is supposed to parse out an HTML document and return my own implementation of an HtmlDocument class. I'm having a problem dealing with the way VS2005 formats an asp.net page by default (markup).
<body><br />
<div style="height: auto; width: auto; overflow: auto;"><br />
<table border="1" width="100%" style="height: 290%;"><br />
<tbody><br />
<tr><br />
<td style="width: 1%"><br />
</td><br />
<td><br />
<div style="width: 100%;"><br />
<iframe src="http://localhost/subtext/" style="height: 507px; width: 100%; overflow: hidden;<br />
vertical-align: top;" /><br />
</div><br />
</td><br />
<td style="width: 1%"><br />
</td><br />
</tr><br />
</tbody><br />
</table><br />
</div><br />
</body>
see the iframe tag? the Vertical-align attribute is shunted to a different line.
How would I rejoin it with its tag, in this case
TIA

There isn't sufficient information to answer your question, let alone understand what's your code is supposed to be doing.
Since CRLF's don't mean anything in HTML, I don't see this causing a problem with a browser.
Does your code parse this up and make a change to a line?? What does the code look like that splits and parses this?? What does the code look like that modifies this stuff and puts it back together??
Are you sure you're not looking at this in an editor, like Notepad, and have Word Wrap turned on??

I'm not sure that's an appropriate title but I can't think of a better one. So far I have the image resizing with the line:
imageBmp = New Bitmap(imageBmp, New Size(imageWidth, imageHeight))
To me that feels sloppy, and so far I can't figure out a nice way to make a single like way to crop, and if I do I feel it will be just as bad. Am I on the wrong track? Am I just over worrying about something simple that won't save/waste processor time/power? Would it be better for me to do both at once (resize and crop) by making a second image and using DrawImage like in the code below (currently it just crops)?
imageNew As Bitmap = new Bitmap(Width, Height)<br />
imageNewGraphic As Graphics = Graphics.FromImage(imageNew)<br />
imageNewGraphic.DrawImage(imgBmp, new Rectangle(0, 0, Width, Height), X, Y, Width, Height, GraphicsUnit.Pixel)
I think I explained this well, I know there are other codes out there I could copy and I know that I'm reinventing the wheel, but I find I learn better this way. I'm very know to VB.NET but have had other programing training. Also this will be output to the web via ASP.NET using imageBmp.Save(Response.OutputStream, I don't believe that matters but I wanted to mention it anyway. Thanks for any help provided.

No, that's what you have to do.
RX Maverick wrote: and so far I can't figure out a nice way to make a single like way to crop,
I think you're asking if there is a "single LINE" way to crop an image. No, there isn't. You have to create a new bitmap the size you want the cropped image to be, then copy the bits from the old bitmap to the new one.
RX Maverick wrote: Would it be better for me to do both at once (resize and crop) by making a second image and using DrawImage like in the code below (currently it just crops)?
You could do it in one operation, but I wouldn't for right now. Get your app to work the way you want first, without worrying about wasting a ton of resources. If you're not constantly resizing and cropping an image, then this code should work just fine. It's one image operation. You're not really taxing the processor at all doing this.
