View 3 Replies[code] objExcelAppDataSheet is the excel application's object and strTemplatePath is the path of the excel file.This excel file is like a template that i am using in my application. In this file some cells are merged. After copying to the new sheet the formatting of the sheet does not remain same. Columns sizes are changing. Why this problems occurs? Is this MS office versions issue??
View 2 RepliesI am using Excel interop in my VB.NET program. My problem is that I can't seem to figure out how to write to Excel *and* define the Range using numbers.Alright, so I have objects being created depending on the file that the user opens. So there could be 100 objects or there could be none. Now each object has an array of values, and these arrays contain nearly 15000 elements. So here is what I want to do but I can't figure out how to escape using the LetterNumber:LetterNumber combination.
For every object I want a new column to be occupied and for every element in the objects array I want the row to be occupied. I figured the easiest way to do this was using a for loop but, again, I can't use numbers.
For columns = 0 to NumberOfObjects
For rows = 0 to NumberInArray
Cell(0,0).Value = myObjectsCollection(column).Array(rows)

I'm working on pasting arrays into excel ranges. Suppose I have a range: A1:A5 and an array a = {1,2,3,4,5}. I can set up the problem like this:[code]So, I got curious about the Transpose method, and whether I could construct my array properly so that I didn't need it. I found that Transpose converts my array into a 2d 1-based array (so the first element is (1,1) not (0,0) as usual).Now I'd like to know: Is there a standard VB-way other than the worksheet transpose function that I can use to build a 1-based 2D array the way Transpose does?

I created an e-mail program in VB2008. I have an excel file with a list of all e-mail addresses and attachments to those e-mail addresses. What I want to do is import thethe e-mail addresses and attachments into my program. I want my program to then take each e-mail address (automatically) and insert them with their attachments into their respectable fields in the program. The primary objective is to insert 200 e-mail addresses and attachments. Each attachement is significant to each e-mail address.

I have to compare two columns in two different Excel sheets and delete the duplicates. I have come up with several strategies that work, but I am searching for the most efficient way to do this. At first, I was sorting the columns and looping through them in the manner of a sequential update and deleting when the cell values were equal. But I discovered here an article by Mike Rosenblum that explained that it is much more efficient to stick the columns into an array and iterate them from there. So I was able to do that. There was a complication in that once I had deleted a row, then the array and the spreadsheet were out of sync. So I had to compensate by incrementing a variable each time a row was deleted, and subtracting this variable from the array index to calculate the row to be deleted in the spreadsheet.
So now I am wondering whether there is a better strategy. I thought that if I could merely hide the rows to be deleted and then find a way to delete all hidden rows at once after the loop was over, then this would eliminate the problem of the array and the spreadsheet getting out of sync and would make the code easier to understand. I thought of putting the row numbers of the duplicates into another array and deleting the rows after the comparing loop. But this creates the same problem of having to compensate the row numbers in the array.
I have to provide an Excel file as an output. I have to color some of lines and make them bold.The input is based on a dynamic list (in memory) and it also could be based on CSV file that I'm already provide today (based on the same dynamic list).I'm wondering what would be the most efficient way (in terms of performance) in order to provide the colored Excel output?Should I export directly from dynamic list into Excel - or - Should I export from CSV into Excel ?

I'm trying to import this info into AD, but in order to do that I need to get the username for these users as well. And I would like vba code or vb.net code that basically takes the value of every row in column D and looks for it in AD and returns the username and adds it to column A. Would something like this be possible?

View 2 RepliesHaving created a small (Excel Automation) VB Appl. to manipulate and present data from Excel sheets in an organised form, I ran across a problem resulting from creating a named range on a sheet, the code line:
oWB.Names.Add("DR_AppData2", RefersToR1C1:="=OFFSET(AppData!R3C1,0,0,(COUNTA(AppData!C1)-2),1)")
seems to work as expected, my only issue here is that this was written on a System that is US-en, and when trying this on a PC DE-de - we have users with varoius language sets - the code fails with a COMException. The only cure I have found to date, is to write the German language version of this:
oWB.Names.Add("DR_AppData2", RefersToR1C1:=BEREICH.VERSCHIEBEN(AppData!R3C1;0;0;(ANZAHL2(AppData!C1-2);1)
