View 11 RepliesI have a program that creates excel and word documents from another main Excel workbook. Essentially it opens excel checks data, posts data to appropriate forms. It then saves them as (number from main excel) & date/time stamp and corresponding extension. I want to be able to list the created documents according to the number from the main excel workbook.

In the following code I open several Excel workbooks from within the VS 2010 .IDE. I want to Try the open workbook code, then Catch exceptions using a dialogbox as a form created programmatically at run-time. The exception handler works, but the dialog box does not display in front of the workbook. So, the user can't respond to the modal form. If at that point the Excel workbook is shrunk manually to expose the dialogBox which is then dismissed, Excel pops up a "Save Changes?" alert and the VB code does not resume the Sub at the Me.Focus() line
When the workbook Is open Excel is the active application. I think this is why the dialog box is not in front, and I don't know how to solve the problem programmatically.[code]...

View 5 RepliesI think I am trying to do something simple. I am using this command:[URL]..Sometimes VB gets hung up opening the website. If this is the case, I want it to quit trying and move on to the next line of code.
For example, try to open the website in excel for 45 seconds. If still not open, skip and move to next line of code.
I have the following function to read an excel spreadsheet and read a certain cell for a value and then I put it into my own List(of T). Everything works fine. However the one quirk I am running into is that as the "oExcel.Workbooks.Open(ExcelFileName)" executes, it does a "Windows Beep" sound.

I have a program that filters data and then outputs it to a tabg delimited file. I then use Excel Interop to open this file in Excel because directly outputting to a worksheet takes too long. So currently I am using this code:
AD.DF.WriteToFile(vbTab)
Dim WB As Workbook = ExcelApp.Workbooks.Open(AD.DF.DatafileInfo.WriteToFileLocation)
ExcelApp.Visible = True
The first line takes the filtered data and outputs to a tab delimited file. The second opens that same file in a new workbook in Excel. And obviously the third makes Excel visible. Here is my problem though: right now when this code is run there are two open workbooks. I already have an active workbook and I would just like to open this file to that workbook.
I am finally switching from VB6 to VB Net and am rewriting a technical application that calculates the heat transfer performance of automotive radiators, heater cores, evaporators, condensers, etc.The user can calculate a heat exchanger and save the results to an Excel spreadsheet. After a series of calculations he can then plot curves of performance.
He can also click on a previous calculation in Excel and import it into the VB routine. The user may have a number of workbooks open when he does this.My problem is I need to open the Excel workbook that is the active workbook. I have been able to select the active worksheet but have been forced to specify the index of the workbook. I have not been able to get the workbook I want.. The code I used is the following,
Dim oExcel As Object = GetObject(, "Excel.Application")
Dim oBook As Object = oExcel.Workbooks(1)
Dim oSheet As Object = oBook.activesheet
How do I get the active workbook instead of Workbooks(1) with an index of 1?
I am trying to transfer data from a VB form to an existing Excel 2003 file. This is the code I am using, but it is throwing up the following error:I have coded in VBA but am new to VB.NET and am struggling with setting up the objects

I'm writing a VB.NET WEB application and I'm fairly new at it. What I want to do is open Excel workbooks on the client workstation so the user can "Save As" or print or basically do whatever they want with it past that point. I've done this in a windows application using System.Diagnostics but all the information I've read so far doesn't seem to work. I can open .txt and .xls files using this approach:[code]but it opens in the browser, which is not what I want. Do I need to mix Javascript with the HTML and the VB code?
View 2 RepliesI have an application the contains several excel files bundled with it. I'm not opening the files and processing them within my application. These files contain a data-connection to reload all of the pivot-tables within each excel file. I have a 'link' on my form, that when clicked, it determines which file to open and calls a sub using filename and executing Process.Start(filename) for any excel file I want to open. I have no problems opening any one of the files and then exiting excel.
The problem is when I 'close' a file, but don't exit Excel; then try to open another file(clicking link on form)... it creates a new instance of Excel.
I know from experimenting that the fileopendialog form will 'reuse' an existing Excel instance, IF it does not already have a file open.
How can I do the same thing without using the fileopendialog?
I don't want the end-user to have access to the folders where these files live. That's why I have multiple 'links' on my form, one for each xls that already exists. I just want them to be able to click on a link and the xls file opens AND if they choose to merely 'close' a file and not exit... Don't create a new instance of Excel, but re-use the existing one.
In building an Excel workbook with VB.Net, is it possible to sort all the worksheet tabs into a particular order? I'm building a workbook with individual sheets named by drive letter, i.e., "C Drive", "D Drive", etc.

Using the new Visual Basic 2005 Express Edition Beta.Created a project, form, controls, etc. Worked great. Love it, compiled perfectly.Saved everything, closed the program, went to bed.

I can open the code, it's all there, exactly as I left it, but cannot get back to the designer mode to (easily) add more controls to it!F7 just opens the code, right-click just gives me code option, not designer option.This is amazingly frustrating..

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 3 RepliesIn the following code why does the message box display behind the workbook,instead of on top of it? It does this related to the line, app.Visible = True. if this line is commented out the message box appears in front, but there is no workbook visible. I've used the message box in other places without a problem. Is there something fundamental here that I'm missiing?

how I might check to see if a specific Excel Workbook (call it Test.xlsx) is open?I have a routine that calls a subroutine. Sometimes at the time of the call Test.xlsx is open, sometimes not. So when the subroutine runs, I need it to check first to see if Test.xlsx is open. If it isn't then the subroutine should open it and perform the subroutine's purpose operations. If it is open, it should not try to "re-open" it or worse open a copy of it; it should simply perform the subroutine's purpose operations.
