I have seen C# code for doing this but was wondering if anybody had some sample vb code.
I have dealt with excel before but usually read/write by creating an instance of excel rather than within the form itself. To do this am i going to have to write to a datagrid instead?
I'm trying to upgrade an Excel VBA workbook to a VSTO Excel Add-in in VB.NET using VS 2010. In the original (i.e.- VBA) version I have a modeless UserForm (called frmMain) that floats on top and is visible at all times while the user is still within the Excel application, but is not visible if the user moves to another window outside of Excel.
For example, within Excel the user can click on any worksheet tab, select any cell, etc. and the UserForm is still visible. This is exactly how I'd like it. The problem is, that in the new VSTO add-in, I can not get the Windows form to mimic this same behavior. I use frmMain.Show() to show the form as a modeless form, but the moment the user clicks an Excel worksheet (i.e.- activates a worksheet) the form becomes hidden behind the worksheet.

View 2 RepliesYou know how you can use REMOTE DESKTOP and see your local drives as a type of SYSTEM FOLDER with a comment of DISK FROM REMOTE DESKTOP CONNECTION. If your browse to a folder you might see the ADDRESS look like this
\tsclientCWindows
What is tsclient? Is that a driver that is "expressing" itself like a folder structure?How about when you plug a camera or other device in a usb port and it shows as a G: drive, for instance?I'm guessing the G: drive trick is just a "driver" starting up for the usb port that somehow makes itself seen as a mapped drive.Is the \tsclient thing done the same way? Is there some kind of tsclient.exe that runs to do whatever this does?How can I make my own "pseudo" folder structure?
Can anyone tell me how to add a Excel like form to a Windows form so I can add and remove rows/colloms and do simple calculation. It would be nice to have tabs along the top.

View 2 RepliesI am converting several VBA projects to Windows form applications. The only problem I have is that some of the functionality of Excel is essential to the application, such as R1C1 formulas. I do not want to instantiate the Excel application or access saved worksheets. All of the data is retrieved by querying Oracle databases. 2-Dimensional arrays are not an option because the columns contain differing datatypes, and DataGridViews are too slow to work with.
I thought simply dimming a Microsoft.Office.Interop.Excel.Worksheet object would be enough, but the program kept failing and upon inspecting the object's elements in debug mode, I found that every value says this:
{"Unable to cast COM object of type 'Microsoft.Office.Interop.Excel.WorksheetClass' to interface type 'Microsoft.Office.Interop.Excel._Worksheet'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208D8-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."}

I can show an excel workbook using a WebBrowser component but that only works if excel is installed on the target computer.Any other ways to display an excel sheet ? Just a viewer.

View 3 RepliesI have two, soon to be many spreadsheet files. There are cell references between the files which need to be updated. I would write this in a excel macro but these spreadsheets are design tables for Solidworks, a CAD system and it does not allow macro enabled workbooks. So what I would like to do is push a button and open all of the spreadsheets, accept the update workbook prompt then save and close the files.
I've seen a similar command developed by someone using the Soildworks API but updating design tables in solidworks takes ALOT of time to run compared to just opening and closing spreadsheets.I am using Visual Studio 2010 Beta 2 along with Excel 2010 Beta 2 (I like to have the new things)

There is no data saved each time the program runs, so I don't have a database.

View 1 RepliesI need a graphical front end for my College project. However the modules that perform the core task (facial feature extraction) have been written in C. This was because the company where I am working on this requires that I code in C. I need a front end to show the results to our teachers in college. Since I do not know anything on working with windows and controls in visual c++, I thought of using VB as I know this language well. What I want to know is how do I call these C functions from VB. Here are some details of my C code.
1. Most functions' return values are just for the purpose of error handling. The output is one or more of the arguments itself (I used pointers for this).
