• Visual Studio Express Editions Space bar

  These codes allow only alpha to be entered in textboxes for Names but does not also allow the use of Space Bar. How will i make it accept space bar input so i could place spaces in the Names Im not familiar with keycodes and keychar, I was familiar with keyascii in VB6 could you give me a reference like Enter = Keyascii 13 in VB.NET.

• Visual Basic How would I use system.net to find hosts on the LAN?

  I've designed an interface for a program I want to make but I'm pretty lost in how to do it now that it's time to code. I was previously recommended to learn about system.net, so I read up a bit. Here's what I'm trying for: Enter partial machine name in a textBox. Click a button and program returns matches that include the string in the textBox. The basic stuff like putting text into and pulling text from the textBox, no problem. The complex (to me) part is what to do about the LAN query. Maybe a tutorial exists on this I've looked but not had much success. Any help, advice or pointers would be greatly appreciated. Thanks, badsign ...Show All

• SQL Server First and Last record in a set

  Anyone have an effecient ideas on how to do the following: For example lets say the data is Temperature over time.For example lets say the data is Temperature over time. DataSet (from a file) comes in sequentially (I've even added a "RowNumber" column). I then drop some temperature records that I determine to be bad.. so the RowNumber sequence would typically look like 5,6,7,8,10,11 etc.. (often the first few readings are bad). What I need out of the set is a bunch of aggregates, High, Low, Average, Count of Readings etc... all those are easy with the Aggregate object in SSIS... however, I struggle to get the starting temp and ending temp. What I have done is multicast the data into the following streams 1. Goes thro ...Show All

• Visual Studio Team System Basic/Digest Authentication support in WebTest? (and NTLM...)

  Is there a way to make WebTests work with Basic/Digest/NTLM authentication   It doesn't seem to work without some intervention (if possible at all). Thanks Yes.  You can set a username and password on the web test.  There is a set credential button on the web test toolbar.  If you click this, it will prompt you for a username and password to use when running a webtest.  You could also click on the root node of a web test and set these values using the property editor. If you want to simulate different users, you can databind the username and password fields. ...Show All

• SQL Server Query Or Stored procedure

  Should I use query or stored procedure to get results fast. Your question is very unspecific. Usually the majority of the query time will be returning large volumes of data. Having a stored procedure is usefull for complex data retrieval or if you want to perform other actions such as logging and for having a precompiled query execution plan. Personally I prefer to just wrap up my report query in a view to keep the logic out of the report and to make updates via SQL. I see no harm in using a stored proc though. ...Show All

• Visual Studio Team System Service Broker Support

  I see basic SSB support has been added. But as you will know, there are always 2 sides involved in SSB communications and large parts of the configuration depends on the other side. What's the recommended way of keeping multiple DB projects synched and what other features will you provide in the future to help aid in this The "Service Listing Manager" supplied by the SQL2005 team is quite buggy and there does not seem to be any more enhancement being done on it. Maybe it should be integrated into this project-type and create/update the elements needed to communicate with the "target" service. Even though pieces are devided up between two or more database; the main schema elements, mainly message types and co ...Show All

• Visual FoxPro Form behavour different if launched from menu or click event?

  I am having a strange problem where the behaviour of a form differs if a form is launched from a menu or from say the click event of a button. The form is top-level with a default data session. I have a few variables that are assigned as control sources to some textbox controls. I am using the destroy event to perform some updates using theses variables. This allows the update to happen regardless if the user clicks the exit button on the form or the title bar. The problem is that the form behaviour seems to vary depending on how the form is initially launched. From a menu the above works fine but from a the click event of a button the variables are not available in the destroy event Does anyone know why the behaviour is not consi ...Show All

• Windows Forms DataGridView problem: Painting takes 1/4 of a second.

  Hello I have some problems with DataGridView . I have one TabControl with two tabs. The first one contains a DataGridView and the second one contains other controls. The DataGridView has its DataSource property connected to a DataTable . This table is set up with 20 columns and has 100 rows. The problem is, when I select tab 1, the DataGridView needs 1/4 of a second to finish its painting. This is really annoying. (Reducing the number of rows does not solve the problem) Is it possible to come around this delay somehow Kind Regards Hi Yes, I see the delay. If I resize the width the delay gets event larger. If I make a full-screen (1280x1024), it takes 0.6 seconds to finish. (Then I have 42 rows and 12 c ...Show All

• SQL Server Reporting Service Web Service from PowerBuilder 10.5 ...

  Has anyone implemented Reporting Service (Execution) Web Service from within Powerbuilder 10.5 I am trying to pass NULL value to the second argument of LoadReport function (to not get the History Snapshot) and the SOAP call gives an error message "String was not recognized as a valid DateTime". I could not pass Powerbuilder NULL (SetNull(StringColl) and StringCol passed as the snapshotID) value as the second argument to LoadReport as for some reason the Web Service could not be invoked. If I pass empty string (or 'NULL' string) I get the following error message. If I pass 'or '1900-01-01T00:00:00', then Reporting Service looks for a snapshot with this date and fails.
