• Visual Studio Express Editions Parsing Text files

  Hi, I have created a vb application that loads the contents of a comma delimited text file to a textBox1. I now want to change the format of the data held in textBox1.text and have the changes shown in textBox2.text, as shown below: textBox1.text = 55, Smith, Fred, Actor, Retired textBox2.text = Fred, Smith, Retired, Actor, 55 Any help with the method to use to re-arrange the textBox1. text string to textBox2.text string would be much appreciated.

• Windows Search Technologies WDS 3.01 and Outlook 2003 (Exchange)

  Somehow I can't select folders from Outlook 2003 to index. The only visible folder is 'public folders' but greyed out because I don't run Outlook in cached mode. WDS 2.66 did show the open inboxes in Outlook and indexed them nicely, in WDS 3.01 they are gone and I can't get them to show. Found the file, it's in the installation file but get deleted after installation from the temp dir. Anyway...

• Windows Forms WebBrowser control freezing up

  I have created a windows forms application containing a WebBrowser control. One of the pages that is loaded by the control contains a Windows Media Player ActiveX object. The movie that is being played in a 500MB mpg and it is set to loop indefinately. After it has been in use for a few hours, the application locks up and must be killed with task manager. This issue is not seen if I access the pages in IE, only if I use the WebBrowser control. I believe this is a memory issue and would like to be able to free the memory used by media player when the page is navigated away from. If anyone has any suggestions or help, it would be appreciated. Mike interesting. firstly why would you play the file ...Show All

• Windows Forms List View HotTracking Property

  Hi, I have a requirement for the HotTracking property feature which underlines list items as the mouse moves over them. However, it appears that the hoverSelection must also be enabled for it to be allowed. The HoverSelection provides a blue background as the mouse moves over the text. This is very poor in response and not required. Is there away to only have the HotTracking without the HoverSelection Me .ListAccounts.HotTracking = True Me .ListAccounts.HoverSelection = False ' not allowd must set to true Ron Nobugz, Although my code above works it is a bit slow in response to a fast hover, that is, the underline is not that responsive to a fast mouse hover. ...Show All

• SQL Server Where to install SRSS DB?

  We're planning to use one instance of SSRS installed for all of our clients. What performance differences could we get when deploying SQL Server DB for SSRS according to the following 2 scenarios 1. On the same server box 2. On another server box I agree with Teo - performance usually isn't a factor unless you are running very long queries. Here are some other things to look at for the scenarios you posted... Backups: If you put the Report Server databases on an existing SQL Server you can simply add them to the backup tasks. Web Farm: If you have the Enterprise Edition of SRS, then you can put the databases on one SQL Server and have the Web Farm set without one point of failure (being ...Show All

• .NET Development Can 2.0 clients call WCF services?

  Can I call WCF services from .Net 2.0 clients Yes they can. It's basically two steps. Once you've created the WCF service, you need to ensure it exposes metadata so the WSDL is available. You then use the WSDL.exe tool, or the Add Web Reference within Visual Studio to target the service making sure you put wsdl at the end of the url e.g. http://localhost/services/myservice.svc wsdl .

• Internet Explorer Development IE7 doesn't show SSL certificate padlock on Status bar

  In IE6, when showing a web page from a secure site (such as my on-line banking account) the status bar at the bottom of the screen showed a yellow SSL padlock icon. IE7 doesn't show this for secure sites. Can I turn this display on anywhere in IE7 as it is the only visible sign that I'm in a valid webpage. I'll not be using IE7 if this padlock is not visibly shown. Hi Bob18, I too had the same issue with IE7 but managed to find the answer on some obscure web page that Microsoft had hidden away....If you haven't already been told or found the answer - the padlock is still there but they have moved it - instead of being at the bottom right of the screen like in IE6, it's now at the top right immed ...Show All

• Audio and Video Development [Seemingly] wrong behaviour for AccessKey:Default handlers in general

  Consider this scenario.... I have tested it on the latest ihd Simulator. =========================== The test content has multiple apps app1 --- doc1 --- has accesskey for VK_MENU app2 --- doc2 --- has event handler regestered for "controller_key_down" ZORDER(app1) > ZORDER(app2) Now, --- when VK_1 is pressed .... "controller_key_down" event would go to app1.... not handled there.. then to app2.... and handled by event handler regesterd on it. fine... --- the behaviour is similar when VK_MENU is pressed. The question is a) When VK_MENU is pressed then I think the event should be deemed to be consumed by the app1 and should not flow to the next app. Refer 7.2.8.1 too. Remember that access-key processing happens AFTE ...Show All
