• Visual Basic reading a string from the right until...

  I thought this would be simple to figure out (and perhaps it is), but I’m not finding it. I want to extract the last part of a string and save it in a variable. The string lengths are never the same, but there are consistent separators, as below: home\work\school\neighbor I need to save “neighbor” in a variable. My idea was to simply read the string from right to left and stop at the first instance of “\” but I am having trouble finding the proper way to do this. BTW, I’m using VB 2005 express Spotty~   Sure enough...that works. Thank you very much. Now I just have to dis ...Show All

• .NET Development Typed TableAdapters with Dynamic ConnectionStrings

  Can a TableAdapter pull its connection string from an app.config file without writing code to read from app.config and set then set its connectionstring property   The literature is fuzzy but it sounds like a TableAdapter can pull its connection string value from an app.config file without writing a line of code to do it.  Upon creation, the TableAdapter wizard offers the option to embed the connection string into your code or write it to app.config .  The TableAdapter then stores the connection name and connection string as properties which can be viewed in the data designer by selecting the Table Adapt ...Show All

• Windows Forms Finding values in a databound combobox

  I have a set of two comboboxes. When the value of combo1 changes I need to change the selecteditem of combo2. The selecteditem of combo2 is related to the particular value selected in combo1. The mechanics of this is easy enough but I'm having a problem. Since the combobox (combo2) is databound, its items are DataRowViews. This means I cannot use items.indexof to search for my value. combo2.FindString and combo2.FindStringExact will not work in this instance because I need to search by the value. I can easily find the DataRow in the original DataSource.DataTable that the value is in but how do I convert it to a DataRowView which I can sea ...Show All

• Visual C# bug in double calculations?

  Hi! I just encountered a strange behaviour of the IDE: If you wannt to evaluate the result of the following expression, if in immediate window or in a watch window, the IDE hangs or crashes: double r = 2.5+(-5/System. Math .Sqrt(50)) * System. Math .Sqrt((25-(System. Math .Sqrt(50)*0.5) * (System. Math .Sqrt(50)*0.5))); Console .WriteLine(r); If you run the build app (debug or release version), it gives the correct result, wich is allmost zero (4,44089209850063E-16). This can be reproduced on different machines. I tried to report as a bug, but cannot overcome the "Profile Center" page showing up immediately after logging in, it alway ...Show All

• Visual Studio Team System General Newb Questions

  I have a few questions, that i've been googling and searching for for a few and just figured I'd ask here in one general place where it may benefit others. 1.  I have two machines, one very large spaced and one not so large spaced.  We want a dual tier setup of TFS with Source Contol.   Am i correct in assuming that the source control database is going to end up on the App tier, therefore we want more space there than the DB tier 2.  Where is there a faq or tutorial on changing the layout of the bug entry page   Adding fields, etc. Thanks! I can only address #1, and Joe's summed ...Show All

• Visual Studio Team System Is there no support for native C++ in Team System?

  The subject says it all.  What test tools in VSTS actually do work for native C++   So far, I've found prefast.  I get the impression from the help that none of the unit test tools, or code coverage tools are usable for native C++.  Am I missing something, or is VSTS not very helpful for native development Another non-unit-test possibility is to set up a generic test (that just opens your native c++ app), configure code coverage the normal way to instrument the app, and then launch the test that way.   This is still linked in as a "test" but it might get you far enough away from the unit testing ...Show All

• Visual C++ CFile GetStatus() Date and Time Help

• Smart Device Development CE.Net 4.2 and Compact Framework 2.0

  Hi, I'm hoping someone can help understand why those of us that work with Industrial Handhelds (and therefore CE.Net) got the short end of the stick.  We have equipment that was just purchased this year with CE.Net 4.2 and Microsoft is not supporting it with VS2005.  It's not like 4.2 was a down-level version, it was the latest version of that build.  Our only options are: 1)  Pray the vendor certifies on the new version, pay additional licensing fees for the OS upgrades, pay to have almost 100 units shipped to Corporate to rebuild and all of this after spending thousands of dollars regression testing CE.Net 5.0 against o ...Show All

• Windows Forms ClickOnce updates all assemblys!

  Hi, I am now trying to deploy with Click Once, and have run into 2 problems/questions. I have 6 projects 1 win and 5 class libs. I seem to think that with Click Once I should be able to make a change to library X and redeploy, in turn the user would only need to download that one assembly. The problem I am having is, a change to 1 library forces the user to download the entire application again. I must just be missing something, what is the way around this Thanks Are you sure it download the whole app ClickOnce is designed to only download changed files. When the user gets an update, the new file ...Show All
