• Windows Forms DataGridViewColumn.Format

  Hi I have DataGridView control where I bind DataSource from one DataSet. Data in DataGridView can be modified. All Columns are Strings however in one column a user should input only digits. When I set Format property of this column to "N" it doesn't work. User still can input e.g. letters. What can I do in order to allow users put only digits in particular column I do not want to create my own class. I hope it is not the only solution. Thanks for hepl in advance E. Hi, You can check out the Int32.TryParse Method (String, NumberStyles, IFormatProvider, Int32) method. It can help to ensure that your numbers conform to the right format. What you can do is place a code ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Starting 3D from 2D

  I come from a 2D background and figure that XNA is a perfect chance to start making some 3D programs, one problem: the math and terms involved are becoming too much for me. I'm looking for a resource to simplifiy the 3D process, I went through the nice video tutorials and got my ships moving and rotating; even got them rotating/moving on all three axis (axi ), albeit with some weird behavior. Terrain terrorifies me, I have no idea on any of it. I'm looking more so for explanation rather then code, I followed reimer's tutorials but I found them incredibly confusing; they seem more angled towards someone to play with the code rather then learn from the explanations. Anyway, please if you have any resources share'em with me because I'm con ...Show All

• Visual Studio Express Editions Automatically enter Text from one Text box to another as you type.

  I would like to setup a Text Box that pulls the Textbox.text from 2 separte text boxes and then displays them in this textbox. For Example... TextBox1.Text = "Jimmy" TextBox2.Text = "Taylor" TextBox3.Text = "Jimmy Taylor" But the kicker is I want it to add the "J" in TextBox3 as I type it in TextBox1 ect. I tried a number of places but I am not sure how to describe this and I am not coming up with very good examples. Thanks in advance for any help. Overwrite the TextChanged event like so: Private Sub TextBox1_TextChanged( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged TextBox3.Text = TextBox1.Text + " " ...Show All

• Software Development for Windows Vista taskbar tooltips - please fix!

  In Windows XP, if you put the taskbar at the top of your screen, as I do, the taskbar button tooltips appear on the taskbar and obscure the buttons - very annoying! Of course, if the taskbar is at the bottom of the screen you don't have this problem, the tooltips appear above the bar, no matter where the exact position of the pointer is. The fix is to always display the tooltip below the taskbar if the bar is at the top of the screen. I like the feel of Windows XP, and I'll probably like Windows Vista too, but this minor point about taskbar tooltips is actually quite important because it affects my experience constantly. Thank you! Taskbar tooltips are a lot different in Windows Vista: you get live ...Show All

• Visual C# Command Line arguments make me say arrg

  Issue I have found a scenario where the command line arguments recieved by an application will fail and three arguments will be concatenated into two... Say one has written a console application and duitfully checks the arguments passed in. One of the arguments targets a path instance. Now the user who is tech savy knows that he/she must enclose in quotes any path that has a space in it or it will be perceived as two seperate arguments. So c:\Program Files needs to be "C:\Program Files" and passed in accordingly. But what happens when a user, say leaves a \ on the end of his/her path Such as "C:\Temp\Dir1\" I will tell you, instead of interpreting it as a literal, the command line parser interprets it as an escape . ...Show All

• SQL Server Dynamic Logging Properties in MS SQL DTS packages

  Since I can't seem tofind the Microsoft SQL 2000 forum, I will post this here: I currently have logging enable on several of my packages. However, we are still in development of our packages and are reaching upwards of 100 and logging will eventually need to be active on all of them. In production, there will still be a development server and a production server, both with different server names and user id/pwd. I am looking for a way to dynamically change the logon information for the logging so that we do not have to have someone go through and manually change the options. I have tried using Dynamic Properties Task, but this only works on the 2nd run of the package. ----- As a second question: can anyone explai ...Show All

• SQL Server Using SSIS packages to process SQL Server 2000 OLAP Objects

  Can a SSIS server, i.e. staging server be used to create packages that update SQL Server 2000 Analysis services objects on another server running SQL server 2000 OLAP   It appears that the OLAP connection manager ion SSIS supports only connections (and thus updates) to 2005 OLAP objects.  I work for a company that has a huge investment in a 3rd party DW that uses Analysis Services 2000.  the DW tool vendor will not support an upgrade to SSAS 2005.  We wish to extend the DW from other data sources.  My thought was to use a staging server with SSIS, used solely as the ETL tool for all new development (thus no more DTS development), and to update the sql server 2000 operational data st ...Show All
