• Visual C# How do I iterate over cells in excel?

  I have an excel file, with a bunch of sheets. Each sheet has a table, but there is not certainty of what row the table starts. But I do know the text in the top left cell of the table. So I want to iterate over the cells, until I find that text, then start reading the data. I can't seem to find any documentation for accessing excel document (via excel interop), although I have found tons of snippets, but all doing fairly trivial stuff. So far I have: Excel. Application lExcelInstance = new Excel. Application (); if ( lExcelInstance == null ) { throw new Exception ( "Couldn't start Excel. Is it installed ...Show All

• Visual Studio Express Editions Cannot Access Free Registration Materials via Thank-You Emails

  Hi everyone. I'm trying to access the free downloads that come with registration, but I only see the Web Developer downloads listed. I don't see the icons, components, or book that come with C#. I assume they would all be listed on one page, but they aren't there. How can I find them Thanks, John Salerno P.S. I don't understand how to download what *is* there either. The link to the Web Developer book says it's a pdf, but when you download it, the file is an aspx file that won't do anything when opened in WD. When opened in an internet browser, it just tries to download itself again. Maybe the site will be updated and fixed tomorrow. ...Show All

• Visual Basic Using the progressbar

  This is what I am trying to do: Copy a file from my resources to the temp directory. Get the size of the file in my resources in bytes. For every byte that is copied I want to step the progressbar by 1. The part I am having troubles with is getting the size of my file. I want to get the size so I can set the progressbar's maximum property to the same value. Also, would it be a good idea to use a background worker for this Thanks. Hi Troy, Here's a little something to get you started with grabbing the file size: Dim fileInformationHolder As System.IO.FileInfo = New System.IO.FileInfo("C:\AVG7QT.DAT") Dim fileSizeInBy ...Show All

• Windows Forms Only Allow 2 decimal places in a textbox.

  I have a textbox which contains interest rate. (e.g. 89.56, 100.00 etc) How do I disallow user type in more than 2 decimal places. (user cannot type in 89.5678 or 80.876876967896) Thanks! The hard way ( but with more control ): Override a text box and handle the key pressed event, using some complex logic to work out where the cursor is and if the key press will result in more than two digits after a decimal place, or if it's generally invalid ( second decimal, non number ). If so, set e.Handled to true. The easy way: Use a maskedtextbox, which will do this for you. ...Show All

• Visual Studio Adding a Database Project using DTE

  Hi All, I was able to add a Windows Application Project in the runtime using the Automation Object Model but I couldn't add a Database Project (including SQLServer and empty database projects).

Can anybody give me a clue for this. Thanks! Best Regards, Imesh If GetProjectTemplate doesn't help, you can use ...Show All

• Visual Studio Team System Build FAILED: A database error occurred (SQL error 8152) ---> String or binary data would be truncated.

  Hi, I'm running Beta 3 Refresh in a single server environment. I've started moving our source code from StarTeam to TF Version Control, but have run into a problem with the build. I started out with a small sample and a simple build file and everything worked fine. Now I've checked a major part of our source code into TFVS and have set up a team build. The build have multiple solutions with multiple projects and several thousand source files. The problem now is that both the large build and the small sample build(that worked fine before I checked in all the source code) fail while checking out from version control. Everything still works fin ...Show All

• Visual Studio constrain the number of a specific shape

  hi, i have three different shapes that i could 'drag&drop' from the toolbox: shapeA, shapeB, shapeC how can i constrain if there is already a shapeA within my designer workspace, that a second shapeA cannot be drag&dropped to the designer workspace The constraint should be, that only one shapeA within the designer workspace is allowed. Any ideas Thanks! Assuming that your shape is mapped to a concept that is directly embedded in the root class of your model, change the maximum multiplicity of this embedding to 1.  That should do what you want.

• Visual Studio Tools for Office Manipulate Bookmarks @ Server Side

  [Using VSTO 2005 Beta 2] I am looking for a way to change text within Word Bookmark controls at the server. I am aware of accessing the Cached objects within the Word Manifest and for instance fill a Cached Dataset with the information that I want to show in bookmarks. What I would like to know is if it's possible to change bookmark information directly using a ServerDocument. The Other thing, is it possible to databind Bookmark controls to a cached data object so that changing data in the cached object is enough to change de bookmark contents The reason for all of this is that the information is at hand at the serverside and it is needed t ...Show All
