Editing Excel Within VB Code
May 27, 2009
First off let me just say i have imports for the excel and office applications. I am using office 2007. I am hoping someone can show me what I am doing wrong here.
I have been searching and researching for a few days now on formatting excell cells within the VB code. It works for most objects such as bold, font size, where i want to place the data and what I want contained in the cells.
I have been using the VBA within excel (macros) to determine the code i should use to format the cells, however, The underline feature doesnt work correctly as with any justification of the cells. or merging. I can't seem to make many of the format options work and am wondering if they are slightly different or if i need a few more code lines so that when i declare something like this...
CODE:
I get an error, xlcenter is not declared. I cant declare it as a string i just recieve a com error starting it couldnt be done.. I am stuck on how to get by these so called "undeclared" command strings that i need to format the cells properly.

I am looking for a way that on the form I am designing , there will be a section that displays an excel type spreadsheet that stores rows of similar information as show below.
length(mtr) width(mtr) height(mtr) cubic weight(kg) physical weight(kg)
eg. 0.15m 0.25m 0.35m 3.38kg 5kg I need the spreadsheet to allow the user to select rows and the form can have command buttons to allow then to delete selected row, etc. But I dont want to have it that the system this program eventually runs on to need to have excel actually installed on the system.

I need to open a .xlt for editing, like so:
System.Diagnostics.Process.Start("Template.xlt", "Editable=True")
But I don't know the correct switch in Excel. This is the same as right-clicking on an .xlt and choosing "Open", whereas the default action is "New".

I am trying to edit, add, and update my database. I have the code for updating and it updates fine (I can see the modified time on the file), but I was wondering why none of my changes were being saved when I closed the window. Then I realized I was an idiot and I don't have any code to actually accept edits on this form, I just have code for updating and adding new rows It wouldn't update without me telling it which rows have been edited and need updating, right I mean I can't just type a new value in the textbox, click save, and expect it to save the change.This is the update and new row code I'm using:
Private Sub SaveToolStripButton2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveToolStripButton2.Click

I need to be able to edit vb.net code using visual studio without stopping the debugging executable.How can I go about doing this? If it's impossible, how can I code and reload that code without stopping the executable? I know of scripting languages like Lua, but I fear the implementation of another language within the VB is unnecessary to save me the trouble of stopping the executable. The issue is that starting and stopping this executable can take a very long time, and I need to be able to edit the code quickly and frequently.

I've tried using the VS 2010 beta to edit some real projects, and it is next to unusable due to performance issues. The cpu is more or less constantly at 100%, and most often the code editor uses around 10 seconds to respond to any text input. If I introduce a couple of compile errors things get even worse. Are there some drastical performance improvements that are planned in the VB editor before release, or are there special things that might trigger this?

Edit 1: Uninstalled & Reinstalled Edit 2: Same problem. Seriously? Yes.I am having a problem with msvb7.dll eating 50%+ cpu on my dual core system. This usually lasts 10-30 seconds or so, during which time the IDE is non-responsive.
This occurs when I do pretty much anything in the text editor, and can be replicated by simply adding blank lines to a function, and then deleting them. Or pasting some code. Or... lotsa stuff.
SP1 installed I had DevExpress' refactor/coderush, components, and codeit.right installed, but have removed all 3 of them. (I had installed the latest version of Refactor Pro! (9.3.4), perhaps the day before)
I have tried a VS.NET Repair. There is a kb that referenced some cpu destroying with vb, but it was included in SP1

I am exporting data from vb.net to excel and it is dropping the leading zero when its displayed on excel. How can I avoid the dropping of leading zero? I read the solution of adding a single quote but it makes my excel sheet column ugly. Also users will complain if they see a single quote on zip code field.vb.net code
Response.AddHeader("content-disposition", attachment)
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
the stored procedure outputs XML and it is transformed by XSLT before it is displayed on EXCEL
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<HTML>

adding a single quote or manipulating excel sheet with column formatter (general/numbers ) etc. I don't want user to make any changes on excel to get the display properly when the excel is displayed from web page it should be all set with proper formatting. also we have no control over client excel software?

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 have one excel sheet which has ontime event of 5 mins to run some code.This code works fine when in debugging mode. But if I lock my PC or minimize excel windows and start working something else, this code just pauses at beginning and as soon as I activate excel window, this code runs.this code involves opening and closing of one userform and i think userform is culprit.

this code was not done by me originally and there are some thigns here i dont quite understand i have altered it a bit from my coworkers code to suit my data and it works. but too slow. and when i have 4000+kb excel files it might freeze altogether. ( I have checked tho that when and after this transposer runs it will still be within the excel row limit, i had done calculations before and made a macro to automatically split excel files based on number of columns and rows to make sure this is so ). This code seems to start out fast then goes slower the longer it runs. at least this is what it seems liek to me.

I have a client who needs Excel VBA code that produces formula values moved to VB.NET. He is in the business of providing financial analytics, in this case delivered as an Excel add-in. I have translated the VBA into VB.NET code that runs in a separate DLL. The DLL is compiled as a COM Server because, well, Excel-callable .NET UDFs have to be. So far, so good: Excel cells have "=foo(Range1, Range2, ...)", the VB.NET Com Server's UDF is called, and the cell obtains a value that matches the VBA code's value.

I have the following code, my employer wants me to reduce the lines of code to do the job.
Private Function getClientSheetNames(Optional ByVal type As String = "all") As List(Of String)
If type = "extra" Then
Return clientExtraSheetNames
End If
[code].....
I am not able to make out how can I cut the lines and have the same functionality !Are there any vb.net construct that can reduce the loc by better implementation ?Can I have a new function to be called from getClientSheetNames and getDevSheetNames that will can implement code resue ?Can I introduce polymorphism in a possible new function ?

I have a little program that I wrote to translate an Excel spreadsheet into a text file and pass it to another application. We found out Friday that if you give it a spreadsheet ina bad format, theprogram just hangs up: no errors and no more processing.It hangs and never finishes processing. If the format is correct, no problems.I wanted to add error logic to catch this condition.So after the try to open the spreadsheet, the first thing I do is check this one cell and if it is not right, it creates and error message, sets an indicator for the error,and closes the workbook.It hangs up on the close of the workbook.A spreadsheet with the expected format closes just fine. I even copied the close statement up to follow the detection of the error, but it hangs just like it did at a different point in the program.
I have been trying to copy the code here, but the question ends up either blank or doesn't get posted at all.The workbook is defined by oWB=oXL.Workbooks.Open("Excel.Application"). oWB.Close() is what hangs. That same code does not hang if the format is correct. How can the contents of the file affect the closing of it?
