• Visual Studio Express Editions long interval between StreamReader/StreamWriter processes

  Hello, in my program I am using StreamReaders and StreamWriters, and they work, but if I use the StreamReader or StreamWriter process, it takes long before I can use them again, so now my question is: can I make the process-intervals(sorry if this name doesn't exist) shorter Or should I use an other way to read and write files, and who can be used in faster time-intervals Grtz, Tom. What do you mean by "it takes long before I can use them again". Could it be that you are getting an exception like "Access Denied"/"Sharing Violation"/"File is in use" etc. In this case probably you don't " ...Show All

• Visual Studio Team System TFS install - problem setting up and connecting with new user

  I have a new installation of TFS (RC), installed on a single server in workgroup mode. I am now at the point of creating local machine users and adding them to TFS. Since there are other system permissions (sharepoint, reporting svcs) associated with TFS admins, i created a local group for this and added it to the appropriate roles in sharepoint, reporting services, and in TFS (when logged in as TFSSETUP of course). However, i did not make this group a local admin (is this necessary ). I am now wanting to create a new user 'userxxx', add the user to my local 'TFS Admins' group, connect to my TFS Server in Visual studio, and create a new t ...Show All

• Visual Basic GDI+ Questions

      I have this beloved old VB6 program that has been converted to a sleek new vb2005 program. It's name is "Color" Color is a utility. It will sample pixels color anywhere on the desktop. It also gives me the x-y coordinates for a given location. It gives me the RGB color value in hex and decimal. I find that I used Color to measure dimensions a lot. and that I'm always having to(x1-x1) and (y1-y2) and awful lot. It's natural that I'd like to use Color to measure anywhere on the desktop or more accurrately what I'm seeing in the moment. So tonight I've been playing with GDI+. It's no problem to: dim g as graphi ...Show All

• Visual Studio Team System error MSB3202

  I'm having trouble building a team build. I am able to define a team build just fine, and when I try to run it, the log files seem to suggest that it can find the source files just fine.

• Smart Device Development DataGridTableStyle MappingName for Details BindingSource

  Hi, I have two grids bound in a master-detail arrangement using a binding source for each grid. The binding source of the master grid has a dataset datasource and a table name for the datamember. The datasource of the child grid's binding source is the master grid's binding source. The datamember of this binding source is the name of the relation between the master table and the child table. The child grid has a table style with mappingname equal to the child table's name. Ok, so that sets up the scenario. Problem is, the table style used for the child grid doesn't seem to work. The column styles I set up with it have no effect, instead, t ...Show All

• Visual Studio Team System Work items seems to use sAMAccountName as key to the AssigneTo field.

  When assigning work items to people the dropdown list displays a list of sAMAccountName . In our case these are very none informative - they don't give a clue to the persons name as it consists of random letters and digits. Is it possible to get it displayed as givenName , middleName , sn or something other more readable When hovering over a user in the team project permission dialog a tool tip displays some other field from AD that is of some help to us in that case. Something similar would be nice for the AssignedTo field. Regards Christer There's been a recent development on this issue.  We have go ...Show All

• Software Development for Windows Vista What registry entry to unblock a VC application in XP Firewall

  Hello, Not sure if this is the right place for my question. While installing our VC based application we'd like to make an entry in the registry for XP SP2 systems such that the Firewall doesn't popup the block / unblock dialog box at runtime. Our application needs internet to run and the EULA mentions it and the user must accept the EULA to install the software. What registry entry do we add to make a rule for the Firewall to allow the application connect to internet without asking the user Thanks in advance I do not even know if it is possible.  The firewall is there so the user has to authorize programs from accessing th ...Show All
