Currently I'm working on some code to modify a spreadsheet before it get's imported into SSIS, using a SSIS script task, so VB.Net.
However I'm having real trouble figuring out the correct code for doing a copy, paste as values for a particular range. In other words: my spreadsheet has formulas in it and I want to convert this to values before it gets imported. I have no trouble figuring out what it should be like in VBA, I just can't get it to work in VB.Net.
Does any one have a clue, or even better a code snippet on how to do this? I can find alll sorts of examples in VB.net for excel just no Copy- paste (as values) ones.
I am trying to write a code for excel so that it generates results in the last empty column on the sheet. below is a sample data of what is there:[code]
View 3 RepliesI've managed to work out how to read EXCEL cells via static values. Ideally I would like my application to check the third column of the EXCEL sheet and if there are no entries on a given row, it should display the coresponding row of colums 1 and 2...for example if (C,3) contains no entry then get values of (A,3) and (B,3)...then mark (C,3) as pending by writing a value to (C,3). Here is my code at the moment

The problem is that for some columns it sets the data type to be Double even though the spreadsheet column format is "Text" and teh column contains non-numeric data. Then when it gets to that cell it returns DBNull instead of the text value.
It appears that when one creates an instance of Excel, using CreateObject, (Late binding), the suggested Excel closing function (with GC.collect etc) does not work. I have tried several suggestions, and the only one that works is process.kill method. Do you see any problem in using this? BTW: the reason we are using late binding is that we cannot use Office PIAs....not sure which version of Office would be installed on the client site. We work with O2003, but the client might still be at 2000 or 2002.
View 7 RepliesI have written an automation addin in Excel with C# (addin.dll). To use the addin, I need to 1. register it using "regasm /codebase c:...addin.dll"2. select in ExcelOptionsAddInsExcel AddinsAutomation the respective addin from the list
I would like to automatize 1) and 2), so that the user just needs to run an exe-file in order to use the addin. 1) should be no problem, but how can one automatize 2)?
Ok basically what I need to do is the following:Read FirstExcelDoc (attached)For every row in that: Retrieve data from sql server db based on info in the Orange columns of FirstExcelDoc Let's say I retrieved data elements A, B, C, D, and E from sql server. Then I need to enter those same data elements A, B, and C in another excel spreadsheet (which has formulas etc) After inputing A, B, and C in that spreadsheet, read a couple of calculated fields and compare those results to data elements D and E retrieved originally from SQL Server DB. Finally, output the results in the Blue columns of the FirstExcelDoc spreadsheet for that row.Loop through and do the same thing for row 2 of the FirstExcelDoc and keep on until you see "END TEST" in the FirstExcelDoc.
I'm looking for a method of doing this efficiently. I have read several articles over the past few days as well as those from Mike R. but just need some direction to get started on this.To start of I'm looking for whether to read the entire FirstExcelDoc spreadsheet or just read the info for first policy number(2nd row) and process it and write out the blue column info for that row and then loop through and come back and read the second policy number (3rd row) etc... Please attach a code snippet for either way of reading the data.
I'm using excel via interop in application.Sometimes users kill application that created excel instance and that results in excel instance sitting in memory without any chance of disposing it.First I tried to tackle this using ROT(running object table) looks like not all instances of excel are registered there.Than I tried to somehow mark excel process after it is started via interop.[code]This works as long as excel is visible but in my case excel window is invisible.All I need is to somehow mark process that started via automation with the parent PID, so that later I can kill it if parent does not exist.

I've got VS2008 and Office2010, but I don't have Office2007. Therefore, I have the Word14 Object Library but not the Word12 Object Library. Will the code that I create for Office2010 automation also work where clients only have Office2007 or will they have to upgrade their office suites?

We have a vb program which is run on our server by scheduled task every day. The program opens about 30 excel files, refreshes the data connections, pivot tables and then saves the document in another location.
This may run fine for a couple days but sooner or later the process starts crashing, usually with this error: RPC_E_SERVERFAULT.
My question is, Is it expected that continually opening/closing/refreshing workbooks will inevitably cause the Excel object to crash at some point.
i was wondering if someone could give me the final explanation on what i might be doing wrong here.I spent a lot of time reading around the net and the forum about how to add Threading capabilities to a VB project.
Nos, i've got .NET 4 installed, and i've added the system.tsr and mscorlib.dll files as reference in, say, Excel 2007 (see screenshot).However, when i try to make a thread with anything as basic as "Dim Thread1 As System.Threading.Thread", i get a user-defined type not found error.Indeed, when i use the object browser to see what's in the System file, theres nothing remotely linked to any Threading, and in the mscorlib file, nothing under "Threading" either, just a few Thread related functions, but nothing defining a data type
I've developed shared addin for Microsoft Word. I distribute this addin with my application and using Inno setup for installation. The Inno setup installs my application and then runs "myAddin.msi" file in order to install addin.
how to uninstall this addin programatically?
Right now, in order to uninstall addin, the user has to to it manually through control panel.

I'm having an issue where my excel.exe process doesn't close until I close my .net application. I'd like to avoid using Process.Kill() if at all possible.
Code:

This method references a couple of other methods I use for repeated formatting tasks, I'll include those methods below. (I added the FinalReleaseComObject into the other methods after reading Mike's thread but the issue persists)
Code:

With rng.Validation
.Delete()
[CODE]..............
Method SetRangeAllBorders does about the same as these other methods but my post is too long to add it. The only other things not shown in these code snippets are a few string variable that are defined in the class, studentWS, studentsWSPW, paymentsWS and paymentsWSPW My App creates an instance of the class, loads some data, runs the method above, and then sets the class to nothing.

I wrote a simple Automation Addin using VB.NET and .NET 4 and want to distribute it's dll to a

possible?
This might seem a ridiculous question but I just want to make 100% sure before I start committing any funds to software purchases. Can I use VB2008to develop automation routines to control Office2010 applications or must I absolutely use VB2010 to do so?I ask this because I installed an Office 2010 pro on my station which already has VB2008 and I do not have any Word14 reference in the COM section of the list of references...
View 1 RepliesI have used VB.NET and Microsoft Offices Interop to create an application that will run on a server and will print files for different users.My problem is that I need to find a way to impersonate different users so that when MS Word opens and prints, the resulting print job is recorded under that user. I found this link that lets you run .net code as a different user - unfortunately it doesn't work with this code. The username recorded is still the user that is logged on the server.Code Removed by moderator. Any ideas how I can make the Office app I'm automating run under a different user to the .net program that is calling it?
