Using Same Code To Generate Excel Files In XP And Vista
Jun 25, 2009
We have an application written with VB .Net (framework 2) that needs to run both XP and Vista machines. The XP machines have office 2003 while the Vista machines have office 2007.The application needs to generate reports as excel files. But when the files are created with xls extension the office 2007 in vista doesn't like the extnesion and gives a message before opening file about the file format.Is there a way to ensure through code that the correct file extension supported by the office version on the machine is used.v

Here is the problem: I have written an application that opens an excel file, copys a chart to the clipboard, then closes the excel file. It works fine except under a very special condition. If the user has an excel file open and then runs my application, the open excel file closes. To make this more confusing, if the user then reopens an excel file and runs my application again, everything works fine. It will continue to work fine untill the user reboots his or her computer. Then it will occur again one time
Here is the section of code I found the problem is in:
Private Sub Get_R1C1_Image() 'Gets excel data to display
Dim objXLS As Object = CreateObject("Excel.Application")

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.

Sub Main()

I am writting an application that stores data in an Access database. I can't put the files in the Program Files directory since standard users can't write to that folder. I can't use a 'user' folder since multiple users will need to access the same file. In addition to accessing the file, users on occassion will copy new versions of the file into the folder, overwritting the old file.Where should I put this file? I am thinking the ProgramData folder, but when I create that folder during the install, it is also read-only for a standard user.I'm lost as to where I should put a file that can be accessed by multiple users, that is read/write, and I can install the folder into the location. I don't think I have a programmatic way of installing a file into the Public users folder.

I'm having some problems with people saving text files using my program, but only people using Vista. Since I don't use Vista myself, I'm not sure what this is but it's not a problem on any machine running XP.
Note that my file saves just using the standard Savedialog box and Filestream/Writeline commands.
From what my customers are telling me, the save dialog comes up fine and there is no error as the file appears to save, but when they look for the completed text file, there's nothing there.

I have encountered a small problem with my application due to the updater I built in.Basically the way the updater works is:1) Check for updates2) Download the new .exe file as "tmpMyApp.exe"3) Download "Rename.exe"4) Launch "Rename.exe" and exit application.5) "Rename.exe" then deletes the old application and renames the tmp one with the origional name "MyApp.exe"6) Launches "MyApp.exe"This all works completely fine for me, except when the program is installed in "C:Program FilesTinyGrab" this causes my app

I have a user of one of my programs reporting that they get an "access to the path...is denied" error during this section of [code]He's using Windows 7 x64 with UAC turned on. The location of "FilePath" is a subdirectory inside Program Files (x86) in this case.I tried to reproduce the error on my Windows 7 x64 system by enabling UAC (I usually have it off) but the program worked fine. However, in my case, "FilePath" is not in a protected system folder like Program Files (where write permissions are not given to normal users without admin elevation).So I tried to recreate this situation on one of my Vista x86 Virtual PCs where the "FilePath" would be inside Program Files. However, my program again worked fine. It had no problems writing to the Program Files folder with a normal user account, UAC turned on and no elevated permissions required.
Thus, I am confused. Why does it work for me and not for him? I want to try an x64 virtual machine but I can't with the software I have (Virtual PC doesn't support x64 guest OSs, VirtualBox won't run the software that my program interacts with). So maybe you guys can help me instead. Are the write permissions for the Program Files (x86) folder different between x86 and x64, or maybe even Vista and 7?

We have code in our former VB6 application, that ported fine to VB.NET, that plays a simple AVI file of the typical "flying folders" and "spinning maginfying glass" AVI. Under Windows XP, our application ran fine and everything was good.
Then we had customers start using Vista and Win7 and this stuff crashes. We were using the MS Common Controls (SP4) and then (SP6) - utilizing the Animation player. Now - these dont work and we get nasty errors.
I searched Microsoft and the web to answer the "what now?" question and though there are numerous suggestions, none of them work. We cant use Media Player because we dont want any menu - just the graphic. We dont know why, with the cool tools given in .NET, there is no animation player (seems a huge oversight...) But we need to get "unstuck" on this one, and we need that fast...
So, How does on play a simple AVI file using VB.NET code? What DLL or OCX does Microsoft recommend and is there a place we can find some sample code for it?

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

Originally I was using Office Interop to import data, but that was a headache and a half for both me and my computer. Right now I'm attempting to load it with ACE, but my data grid isn't being populated. Once that's up and running I need to know how to use that data in other ways, and how to grab specific cells of data from that dataset. I'm using Visual Studio 2008, by the way.

Problem 1: I am running into a problem with my program that when UAC is active on Vistaaccess to C: and Program Files is not allowed. My program writes text files as a user types. Is there a safe place to write files to that may be some sort of standard instead of throwing files all over the place? Like maybe somewhere in the user's default folder's or something?

I'm trying to generate a pivot table in Excel using VB.NET 2008. I need to bring the data into one tab, and then generate a Pivot on another (i can't do this externally because the data is pulled from a bunch of different places). Currently I'm doing this pivot in the actual code, and then writing to Excel, but it takes up a lot of resource and time and this will make things much easier! I created a sample list below, and I am trying to generate a sample pivot table based on it, but I'm getting errors:
Dim wb As Excel.Workbook
Public Sub ExcelGen()
Dim ex As New Excel.Application
[code]....
The error I'm getting right now is the no object reference set error on the "pCat =" line...

Im working on an AutoUpdate class for a small application I've been working on, and with Windows 7 and Vista machines I get a permissions error when trying to replace some of the files in the Application folder. The only way to get it work is to run the application as an administrator. Is there a way I can either attempt to automatically run the app as administrator, or a way of replacing the files that won't be blocked by Vista/7's permission gatekeepers?
