• Visual C++ VS.2005 constantly crashes when trying to compile, start or debug an application

  Hi everybody, We are currently trying to migrate our (unmanaged) C++ code base from VS.6 to VS.2005. Some smaller projects have already been migrated successfully, but unfortunately, we're experiencing lots of problems with our major project (which is a single big application build from about 4.000 C++ files in several static libraries). The main problem is that VS.2005 constantly crashes whenever we try to compile, start or debug the application. This may sound odd - since one cannot start an application without beeing compiled - but we've managed compiling the project using the IncrediBuild plugin. However, if we choose "Build Solution" (or "Rebuild Solution"), or try to "Start Debugging" or "Star ...Show All

• .NET Development XML

  How to make the page well formated using XML Your post is cryptic. What is "the page" Do you mean "file" or "document" instead of "page" XML is always well formed. If you try to process file that is not well formed with XML tools they should give you an error. Fixing this errors one by one you can format your files according to XML rules. You can open XML files in the VS XML Editor. It should all errors and helps you navigate to the position in the file where you can fix the error. ...Show All

• Visual Studio Team System Best Practices for Data Generator Based Tests?

  I'm having a bit of a hard time grasping how to make meaningful tests based on the randomly generated data vs making my test in a transaction where I feed it initial data and check for an expected outcome. For example's sake if I had an SP called DivideTwoCols that would divide colA by colB in table0... If I were making tests with known data, I'd probably make a test using two positives, one negative and one positive, two negatives, colA = 0, colB = 0, and no rows in table0. If I were just testing randomly generated data how would I know I had my cases covered would the random test just pick a random row to try it with using select top 1 colA, colB from table0 order by newid() I can appreciate throwing in some randomness in te ...Show All

• SQL Server SQL Server Integration Services and Web Service timeouts

  Hi, A coworker of mine is experiencing some problems with SQL Server Integration Services (SSIS) and long running Web Service calls. Any feedback on the problem would be greatly appreciated. The problem is as follow: He has a large SSIS-package that, among other things, contain a few Web Service Tasks. All of the tasks are executing as expected for small amounts of data. All the Web Service Methods have in common that they have a long running time. The running time depends on the amount of data. During requests with large amount of data the Web Service task fails with the error message “The operation has times out”, but on the server they see that the service call completes as expected (after quite some time, approx 200sec).

• Windows Forms Watermark TextBox in winform

  Trying to create a control like Atlas control that will put a watermark inside a textbox while it is empty. My original idea was use UserControl1_Enter and UserControl1_Leave and set this.Text appropriately, but this method could foul up other code using the Text property. My next idea was to use the Paint method, but I am not even sure that TextBox has a OnPaint event at all. Any tips Jon, as far as I know there is no way you can override the painting the a TextBox control, short of drawing everything yourself. There is a solution that should do the trick for you, though. You will need to sublcass the TextBox and override a few things. Consider the following code I put together (far fr ...Show All

• Visual Studio Team System Code Coverage Results in Web Tests - "Empty results generated: none of the instrumented binary was used."

  Code Coverage Results after running test: Empty results generated: none of the instrumented binary was used. Look at test run details for any instrumentation problems. The test run details show a warning for each of the assemblies regarding instrumentation, but this leads me to believe that the instrumentation process succeeded: Warning VSP2013 : Instrumenting this image requires it to run as a 32-bit process. The CLR header flags have been updated to reflect this. My scenario: In trouble shooting this, I’ve scaled down to a single test that logs into the site and views a single page.

• Visual C# Adding a item to a IDictionary<String, List<String>> object

  Hello! I know this must have an stupidly easy solution, but now I just can't find it :( I have this collection: IDictionary<String, List<String>> publishers = new Dictionary<String, List<String>>(); The keys will be some web publishers names, such as "wired.com", "internet.com", etc. The values associated with these keys will be lists of urls (I'll be reading the urls from a txt file).

• Software Development for Windows Vista Reading a Hard Disk Serial Number

  Hello, I am testing an application which reads the serial number of the first hard-disk (C:\). The application is written in VB6 to work on Windows 95 through XP and I am currently testing it on Windows Vista. I am using the function DeviceIoControl from "kernel32", to read the serial number on disks that have SMART technology enabled. While testing, I noticed that I get a different serial number if the application is opened with the limited access user account or with administrator account. I suppose the real disk ID is shown when the application is opened with administrator privileges, but then how is the other number generated, and is it unique, or at least randomly generated once on each computer Thanks for your help, Davi ...Show All
