Error Creating Directory And Saving Excel Workbook On Vista?
Mar 2, 2008
I have a VB.net applications that runs on XP and creates a directory and creates an Excell workbook and saves it. But when I do the same in Vista , when it tries to create a directory to save the excel workbook, it gives me an error that the directory does not exist. If I create the directory manually, it still gives me the same error. Is there a COM call for office 2007 on Vista other than worksheet.SaveAs(FileName:=path). All else works on Vista apart from creating a directory and Saving Excell Worksheet.
Public Function createDirectory(ByVal path As String) As String
Dim new_path As String

I have a macro run program I have created using excel 2007.The excel version makes use of VBA designed userforms and macro code to run and it stores data within a worksheet.It populates some of the fields in the userforms from drop down boxes whose pre-populated values are stored within another worksheet in the workbook.If I was to create this within vb.net how would the drop down box values be stored? and also: would it be easy to have the userform on-close click event send the data to be stored in an excel workbook ?

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.

I am trying to use the BGW to save a DGV to excel file, but don't know how to do it correctly, specifically setting the savefile name this code doesn't work gives me:
'System.Runtime.InteropServices.COMException' occurred
- Make sure the specified folder exists.
- Make sure the folder that contains the file is not read-only.
- Make sure the file name does not contain any of the following characters:
Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process. I also tried doing the Save in the BGW RunWorker Completed event but then there is no file name. It seems I need to pass the file name the user inputs in the SaveFileDialog to the BWG WorkerCompleted event somehow
Private Sub excelexp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles excelexp.Click
ProgressBar2.Visible = True
Saving.Visible = True

I use the following code snippet
Dim exlapp As New Microsoft.Office.Interop.Excel.Application
Dim xlWorkBook_new As Microsoft.Office.Interop.Excel.Workbook
Dim strOriginal As String
strOriginal = Server.MapPath(Request.ApplicationPath & "/Attachments/") & "abc.xls"
xlWorkBook_new = exlapp.Workbooks.Open(strOriginal)
The code hangs in the last line. It works fine in the development environment. i deployed in windows server 2000 ,where I get this issue. the browser goes half way and throws the below exception after some time

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.

I have an Excel file with utilizes macros to allow a user to enter names of people and then double click on cells to enter ratings via radio buttons. When I open a blank file and enable the macros, I can add users, rate their skills using the radio buttons, etc. with no issue. I then SaveAs the file and continue working on it. once I Save and CLOSE the file, then go to re-open it, the trouble begins. Keep in mind, there is no alteration to the macros directly. Just entering data and using the form as intended. Here's what happens.
I reopen the file.I enter in the name of a person on one line. I go to the first box - double click on it.It is supposed to pop up a dialog box which allows me to choose a rating via radio button (as I had been doing before I closed the file). Instead, in that first column of ratings, it instead gives me the following error:
Runtime error '1004'Unable to set the LineStyle property of the Border class
When I hit "debug" this is the code it points to:
If ActiveCell.Column = leftb Then Range(Cells(ActiveCell.Row, leftb), Cells(ActiveCell.Row, rightb + 1)).Borders(xlEdgeTop).LineStyle = xlContinuous I have no idea why this would not work when I re-open the file!
note that when I go to click on the subsequent cells (there are 8 cells in which you provide ratings, moving across the columns with each cell) - the 2nd through 8th cells function fine. The dialog box pops up, the rating can be selected. it's just the FIRST cell that gives the issue What would possibly be the cause of this? We need users of this form to be able to save, close, and re-open it if needed.

In 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?

I'm trying to generate Office 2010 files (xlsx) in a vb.net project (Visual Studio 2010 fw 4.0).On my developing PC it works. Once on the server it generates an error:Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).On the server I tried with dcomcnfg and navigate to DCOM Config and locate Excel. To solve the problem I would have chosen Customize in the Security tab under Launch and Activation Permissions and add the account under which the site is running (our server task user) and assign Local Launch & Local Activation permissions.[code]

My question centers upon the two approaches, (1) and (2), shown below, to declaring Excel workbooks in .Net.The two approaches interact differently with the lines "wkbk10 = app.wkbk10.open()" and later with
Range references to this workbook,like "rng1Stocks = CType(wkbk10.Sheets(1), Excel.Worksheet).Range("H5:H30")".

I 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 a .Net program that responds to worksheet updates of an Excel 2003 workbook. Sometimes when the worksheet is updated and I try to write related data to my forms, I'm getting "Cross-thread operation not valid...." errors. This confuses me, as I have never done any multi-threading in my program. Does the mere act of me responding to events of an external excel worksheet mean I am now multithreading? Is there a way to handle the events without multithreading?

I am working on an application where I need to locate a range of cells within a worksheet. Since the actual location of the data will vary for each worksheet, I have come to the conclusion that I can put a string near the range that I am looking for (i.e. the text "*SUMMARY*") and since I will know the location of the data that I am looking for relative to the location of this text string, it should work.
I have made some progress but am having trouble getting the Find method of the range component to work. My code is below. This code finds each worksheet and shows me the name but I also need to to find the location of the cell with the string "*SUMMARY*" in it (if it exists).

I have a little problem with a small application that uses an excel workbook, and i don't know what's the best way to handle this.In the past every computers here in the company had the same culture and the same office version/language.Now the company bought some new machines, that came with english version of the office (en-US). Now the program doesn't work, throwing the exception related with the assembly of the office.
I have two solutions to solve this, install the mui in all the computers, or the one that i want, adapt the application to work independent of the culture in the client machine.So how to accomplish this? Set the application culture to the same culture in the computer (i think this will not work, because the excel assembly that i ship with the application isn't the correct one for the client language it's the assembly of my machine language)... One copy for each language, once again it's not possible

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?
