• .NET Development Escaping decimal points in regular expressions

  I'm trying to do something that ought to be very simple. I'm trying to test whether a string (which is an argument to a command) is a valid value of the type I need. That is, I want it to be convertable to a double and be in the range 0.1-1.0. I have this line in my code: Regex ValidPause = new Regex("^((1\.0)|(0\.[1-9]))$"); The problem is that VS marks the string as bad and gives me the message "Unrecognized escape sequence." If I take out the backslashes, the red squiggly line goes away, but then it matches "0x0", which is obviously not what I want. How should I escape the decimal points correctly Actually, it does work to match what I meant it to match. I just wonder, si ...Show All

• Visual Studio Express Editions Running a shell command..

  Hi, I'm having troubles with running a shell command. I'm using this to initiate an existing remote schedule on a domain controller. The tool from which the shell command is run is used by helpdesk people (with no rights to start a scheduled task on a dc). Now, I started by using the schtasks.exe under an account with the right permission. This doesnt seem to work. Then I thought heck, I'll use runas.exe from MS and start the schtasks from there.. Nada too since passwords are not allowed by default. So after searching around on the net I found this tiny app sonur.exe which can be used in conjunction with runas.exe. It basically allows poking the password in the command line together with runas.. So, you get something like this: runas ...Show All

• Visual Studio Team System 500-InternalServerError when running load tests

  When I ran my Webtest, I was able to complete the test execution without errors...but everytime I ran load testing, many '500-Internal server error' occurs... Also, when I look at the Test Summary part of the results...It shows the number of tests and the Failed Tests fields...in most cases both of the values here are equal...yet I know for a fact that there are successful tests since there's an email notification received everytime a user completes a registration. What I'm not really familiar with is what are these 'Tests' being referred to in the Test Summary part Does the value in the Total Tests field mean the total number of times the webtest was completed Thanks! But it seems that there are ...Show All

• Windows Forms Make sure you are not dividing by zero.

  I am getting this message at this statement: g . DrawLine ( p , xPos + offset , yPos1 , xPos + offset , yPos2 ); g is an instance of the Graphics Class. It is not my code. I am trying to adapt NPlot package to my main application. The whole thing works well when NPlot uses an XML file (DataSet) that comes with NPlot. I copied the schema to another file and input my own data into the dataset and this error sprang up. I do not understand what the difference really is since I tried to copy everything slavishly. There are no dividions in the set of parameters. I cannot figure out why this message is appearing. Thanks. More and more good pointers. Many thanks. BTW NPlot is www.NPlot.com It is a good package. ...Show All

• Visual Studio Vss 6 and vss 2005 Migration?

  1. Visual Source Safe 2005 will be a standalone product or will it be part of Team Foundation Server 2.

  hi, I want tomake wcf and service broker communicate with each other,the question is how to write wcf so that two sides can communicate. thanks in advance Hi, That is not something easy to do and require a lot of custom code.

• Visual Studio Express Editions Another Problem

  Hi, I was wondering if there is anyway to turn a huge amount of code into a simple function. Right now I have a bunch of check boxes and they are all named C1-C7 and W1-W7, instead of putting in code for each one when clicked, which results in a large amount of code, is there anyway I could make one function to handle all of these. I tried something like this. If C(num).checked=true then W(num).checked=false endif its just a basic example of what i want and i could really use this later on. Thanks Well WayneSpanglers example does work but the other one might be nice for future use, ad thanx for showing me how to use cases.    Just note that all the cases ...Show All
