Your statement will evaluate to a comma when both role and roleUp are not empty otherwise it will evaluate to an empty st ...Show All

  Hello All, I've been trying to make multiline labels. That's not possible through code That dissapoints me. Keehun Knvb1123, Here is another suggestion on how to achieve multiline labels. Instead of sprinkling the text with vbCrLf characters, I found that if I set the label's MaximumSize property to the size of the label, the text will line-wrap within the label. The AutoSize property must also be set to True. I found that it is easier than playing with where to insert the vbCrLf characters. Best of luck. ...Show All

• SQL Server Error when attempting to backup to a second disk file

  In SQL Server 2005, via the GUI, I wish to backup a database to an additional disk file (there is already an existing backup disk file for this database), so that I can have more than one backup. I've added the new disk file name, highlighted it, and clicked OK. I get an immediate error (see below).

• SQL Server Return empty rows for not existing data - possible?

  Can you help me solve this problem, please. The main table t0 seems not to be relevant here but contains all the unique information to an article. Each article can have many ingedients and several other 1:n related things. The one I have difficulties right now is t1 (analyse). Each article can have entries for 0 to 15 types of analyses that are stored in t2. Now I need a web entry form that lists all types of analyses with either the existing values or empty fields. It's no problem for me (althouh not very nice) to store empty values on save but I need to show the form even for new articles or existing artices that have no entries yet for analyse. I tried something like this: SELECT t1.id, t1.analyseid, t1.analysetyp, ...Show All

• Windows Networking Development Vista RTM can't open new socket.

  Started here . Due to (stupid) limitation in TCP/IP driver (10 half-open connection) sometimes Vista loosing ability to access an internet (open new socket for communication). It happens when user uses P2P applications (BitTorrent, eMule). But in could be caused even by too busy IIS. BUT all existing internet-connected programs (WLM, Skype) are running. PC even is accessible via RDP. No any entries in EventLog relating to any problem with sockets. "Event 4226" appears in absolutely different time, not in time when connection was blocked. Only reboot or (sometimes) "Network Connections" (and ICS) service restart can help to revive network back to live. This problem is accepted by many people (see post on Channel9).
