I am trying to read text from an image. I have been trying to use OCR from MODI but I keep getting an error. Here is the simplest version of code (I've tried several)
Dim miDoc As MODI.Document
miDoc = New MODI.Document
miDoc.Create("C:document1.bmp")
miDoc.OCR()
miDoc = Nothing
As far as I can tell, my program gets stuck every time it gets to:
miDoc = New MODI.Document
it tells me a COMException was unhandled
I am using vb in vb.net, and I have a reference to the COM "Microsoft Office Document Imaging 12.0 Type Library". Every thing I have tried seems to come up with the same error.

I am trying to save an object (Class1) as string in a cell value. My issue is that from time to time I have a ComException:HRESULT: 0x8007000E (E_OUTOFMEMORY)(It is kind of random but I have not identified any particular pattern yet) when I write the value into a cell. Any ideas will be welcome
For illustration purposes:

I have done quite a bit of research on this issue and haven't came up with anything definitive yet. I am having issues with Excel randomly getting ComExceptions while writing out reports. I am using a Visual Basic 2005 (framework 2.0) console application to create these reports. The problem has been difficult to figure out because it occurs in random places while writing out reports so I can't catch the error to see the problem. I have looked through the differing items that it breaks on and there is nothing odd about them that would cause any of these problems.

I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

View 8 RepliesI would like to prompt the user, in the middle of a VB program, either with MsgBox or any other dialog, to input data in a worksheet of the Workbook that contains the code and then, on some event, read the data and continue execution. I was not successful with MsgBox (and other forms) since it is modal. The user cannot get focus on the worksheet, input data and then continue execution by clicking a command button.

View 3 RepliesI have a bunch of Excel files, each file with multiple worksheets (aka, tabs). I want to loop thru each file, and within each file, loop thru its worksheets and do some stuff. I've included Microsoft.Office.Interop in my code and I am able to do Excel operations but I am not sure how you loop thru the multiple worksheets within a workbook.
Here is what I have so far.
Imports System
Imports Microsoft.Office.Interop
'The command take one argument.
'It is used to locate the current source directory where the Excel files are saved.
'The command will open each file and loop thru the tabs in the file.

I know I havent posted in awhile but you guys have done such a good helping me, my projects have been a breeze lately I have a new challenge though and I cant seem to figure out the solution. This new project Im working on sends a range of cells from an excel worksheet to the body of an email message and attaches two files.
I already have the automation down for the population of the excel file.I just need to copy Range A1:F20 from xlsheet3 to the body of a blank email with a populated subject line.Ive checked out this site already [URL].. but he seems to be accomplishing it with excel where as I (if I can) would like to do it in VB on VS .
suppose I have an excel worksheet, I want to paint the particular cells with gray color then save it as a new file.
View 3 RepliesMy application searches for a specific worksheet in an open workbook. The code to find the worksheet is:
If Amendaction = True Then
If oBook IsNot Nothing Then
For Each ws As Excel.Worksheet In oBook.Sheets
If ws.Name = SheetToFetch Then
SheetFind = ws.Name
[code]....
When I execute the code, depending on the worksheet name, the result found in ws.name has one or more spaces in front of the text. e.g. "Bour001" used in creating the worksheet name becomes " Bour001" when returned by ws.name.
I have been asked to create import functionality in my application. I am getting an excel worksheet as input. The worksheet has column headers followed by data. The users want to simply select an xls file from their system, click upload and the tool deletes the table in the database and adds this new data.
I thought the best way would be too bring the data into a datatable object and do a foeach for every row in the datatable insert row by row into the db.
I want to insert worksheet object on a VBA form for AutoCad. I had done it before. But now I can not recall which object was used for this.
