• Windows Forms Multiple installs, multiple versions, multiple sources

  We've got a situation where our consultants will go into multiple customer sites and have to run a specific application that's installed from servers at each site.  The customers may each be on different versions of the application, but the consultant will have one laptop and will need access to each version. Will ClickOnce set up different instances of the app in different folders automatically If not, how can the application, or manifest, be modified to allow for this   I know I can't change the install location itself, but I do need the described behaviour to be supported.  Will simply changing the codebase attribute ...Show All

• Visual FoxPro older scatter gather, and VFP.

  Hi; I have a form which the user fills. The info the user enters need to be added as a record in a table. In the Foxpro2.6 world I used to do this by letting the user edit empty memory vars, and then append blank / gather from memvar. I am wondering if there is a better way to do this in VFP9 I know I can use buffering then tableupdate(), but that requires that I would append blank FIRST before I let the user edit the fields. I would like a way for the user to edit the fields, and if he cancels out, to be able to revert the table to its condition without an empty record. I think maybe transaction processing might be ...Show All

• Visual Studio Express Editions Problem with bound Checkboxes

  I am developing an application in V C# Express and am having a problem with binding checkboxes to bit values in SQL Server express. This happens if I drag the control from the datasources window or if I make a new checkbox and bind it to the field in the database. The default value for the checkbox is unchecked, which should equal a bit value of 0 if I understand it correctly. When I call this.audited_ItemsBindingSource.EndEdit(); I get a null not allowed exception for the field bound to the checkbox. It doesn't matter if I leave it unchecked or if I check it, it is still generating the expection. Hi, Pl ...Show All

• Visual C++ Memory Leak in C++ STL library - Visual Studio 2005

  There's something wrong with the ios_base class in Visual Studio 2005. I was debugging my program and I noticed a memory leak. Since I could not understand what was causing that leak, I've tried using a memory leak detection tool (Rational Purify) and I found that the ios_base class causes a memory leak. I just tried to write this piece of code #include <sstream> int main(void) { std::stringstream myStream; //nothing else return 0; } The memory leak detection program tells me that: --Memory leak of 4 bytes from 1 block allocated in --std::basic_iostream<char,char_traits<char>::std>::basic_iostream<char,char_traits&l ...Show All

• Windows Forms How to catch the row change event in a datagrid?

  Hi everybody, How to catch the row change event in a datagrid I'm using VB.NET. I have a datagrid filled from a table. I want to raise the row change event when the user selects a row. I found the code for it in C#, but I want an example in VB.NET. You are right, it doesnt have the Row Change Event implicitly. You will most probably have to use either the CurrentCellChanged event or the Click event. There is a protected event also for row header clicks : RowHeaderClick ...Show All

• Visual Studio Team System What does MS use for Requirements Management?

  I know that Microsoft is dogfooding VSTS, but what are you using for requirements management I have seen on these forums multiple posts about Caliber RM for Team System and most say that if you are really serious about requirements, you won't use VSTS alone. I highly doubt MS is using Caliber for their requirements management, but I guess pigs do fly from time to time. When VSTS was used to build VSTS, did you just use scenarios to capture the requirements Just a, observation, since I don't work for MSFT, but the impression I get is that most MSFT teams use MS Office apps - Word, Excel & PowerPoint to manage requirements and specif ...Show All

• Visual Studio Generate documentation under .Net 2.0?

  I really need to generate some documentation under .Net 2.0. I know that this issue has been raised in a previous post few month ago, but no explicit solution has been provided. Also the NDoc project seems dead (as suggest the broken wiki). Does anyone has a practical (even minimal) solution to generate documentation for .Net 2.0 Thanks in advance, Joannes Hi All, If you haven't already seen this, here is the hyperlink to the latest NDoc05 Beta on sourceforge: http://sourceforge.net/project/showfiles.php group_id=163095 Hope this helps, Kind regards, Frank M.

• Visual Studio Question about Microsoft.VSSDK.UnitTestLibrary

  What is the expected way to handle strong-naming for this library My test package(s) are all (delay) signed and using this library for testing fails because it is not strong-named. I assume that it's OK to build this locally so that I can sign it for use in my project(s) If so, what is the suggested usage of this library Should it be included in each solution it is used in We are investigating. As a workaround, you can skip the strong name verification for this assembly using sn –Vr Microsoft.VSSDK.UnittestLibrary.dll ...Show All
