• Smart Device Development Problem when power button pressed

  Hi All, I would like to ask on the way to control the "power-down" behaviour of application in Pocket PC. Currently, when the user press the power button to turn off the monitor, and then press it back, the application is still working (sound etc) EXCEPT the graphics (I use picture box) is freeze indefinitely. Can I know how to work around this problem Thank you in advance for the replies. The SDF v2 wraps that nicely for you: http://blog.opennetcf.org/ctacke/PermaLink,guid,cf2c3926-e875-4a25-b635-39e227b358f5.aspx ...Show All

• .NET Development ASP.NET Won't work

  Ok, so I install Visual Studio 2003, and then IIS 5 on my windows 2000 machine. I start up Visual Studio and attempt to create a Web Application. It informs me that I only have asp.net 1.0 and I need 1.1 if I want all of the features. The problem here is, I have the .NET framework version 1.1, so I should also have asp.net 1.1. I click on the thing that says use asp.net 1.0 instead. It then informs me that I do not have the web development stuff installed, when I do. I tried removing everything and putting it back, I had .net 2.0 stuff on it before but that is all gone now. I can't figure this out, there is no reason that it shouldn't work. ...Show All

• Visual Studio Team System How to: Add Data Binding to a Web Test

  According to this walkthrough: http://msdn2.microsoft.com/library/ms182546(en-us,vs.80).aspx I should be able take values from a Table Column and use them as values for QueryString Parameters. In my case, I want to use them as Form Post Parameters instead of QueryString but either way, I get the same result: First, When I add the Data Source, the thing says something like 'Invalid Object' when I try to run the test, My data Source is AdventureWorks1.vEmployee and the only way I have been able to get rid of this error is by editing the Data Source in the XML to say "HumanResources.vEmployee" in the <DataSourceTable> tag.

• Visual Studio Install VS 2005 Standard Ed Hangs on Executing Action: RemoveTempHxDs

  I have a 1.2 Ghz Dell laptop with 1 gb of memory.  I started the install almost 16 hours ago.  MSIexec is using 97% of my cpu.  The install failed 2 times before this, but it gave me the option to send a report to MS.  This time I'll just have to kill it.   I have the version that was given to me at the Chicago launch.  I have uninstalled Beta 2 and VS 2003 without any difficulty. Same problem. Solution: I concur with those who have suggested copying the files from the CD to a local or network drive (then installing from there). This solution worked for me.

• SQL Server Inconsistent behaviour when setting up parameters

  Hi guys, i am having an issue setting up two parameters in the report designer (SSRS 2005). The report is calling a stored proc, these two parameters are optional, when the user decides to run a report i don't want them to input anything for these parameters, they should both be set to null when calling the stored proc (changing the signature of the sproc is not an option). So, in the Report Parameter dialog, i set both parameters to "Allow null value", "Internal", and default value of null. This is when the first issue strikes: if i "OK" out of the dialog, then save, then go back into the dialog, the ...Show All

• Visual C# The sbyte type

  Hi, In Learning C# by Jesse Liberty, the author states that the sbyte type can store numbers from -128 to 127. I was wondering whether or not the last bit (8th) is used to store the number's sign. If it does, then how can the remaining 7 bits store a number as large as 128. The largest number that 7 bits can store is 127. So shouldn't the range for the sbyte type be -127 to 127 instead of -128 to 127 as the author has specified. Please clarify this confusion. Thanks, Karim Hemani Yes, the top bit is always used to store the sign. However, bear in mind that this means you have two values for 0, one ...Show All

• Visual C# How to connect to Oracle Database with VC2005

  Hi: Can somebody throw some light on how to make an oracle database connection with VC2005. The only options available are for MS Access and MS SQL server in the data connection wizard. Thanks, Jyoti Seems to me it's working if your getting an ORA-01036 error.  You're issue may have more to do with Oracle than with what version of VS you have.  Google "ORA-01036" and you might find what's causing it. ...Show All

• Visual Studio Licensing & pricing

  I thought I should start a thread on licensing and pricing where we can give some feedback to MS on the type of scenarios we intend to implement and how various licensing & pricing schemes would interact with that. As I see it there are two separate questions here: 1) What license is required to author a DSL 2) What license is required to use a DSL For 1) I guess the main question is which edition of Visual Studio will be required, and whether one will need to join the VSIP program in order to author and distribute a DSL widely. For 2) a lot more questions come to mind: a) Which version of Visual Studio will be able to host a DSL b ...Show All

I'm making a very simple movie database program and I want to be able to take the text typed in a Text Box, write it to a new line in a text document (and save it), and also read text from a line in the document, and then convert that to a string to be used in the program.
