• Visual Basic Launching a Precess from Ram

  Starting a process requires a file path to a disk location.  I would prefer to not create temporary files on client computers for a number of reasons.  Can love or money buy a way to start a process from memory with the data file represented as a byte array or a memorystream.   Thanks, Fred Herring No, a ram disk is out.  If I don't want to write to a clients disk space, I definitely don't want to steal his/her memory.  I would like to leave the thread open for other comments.  It seems like such an obvious capability for launching a process.  I know of two third party component makers (Farpoint ...Show All

• SQL Server Connection handshake failed - easiest possible configuration

  Hi there! Often discussed, but not really solved in my opinion - the connection between the partners and the witness causes problems. My case: Three Servers in the same domain, three endpoints on 5022 with windows negotiation, all endpoints can be reached by telnet from each server. Mirrorring works. So far so good. But one of these partners is not able to connect to the witness. The witness' error log is full with that: "2006-06-01 13:45:20.32 Logon Database Mirroring login attempt failed with error: 'Connection handshake failed.

• Visual Studio Express Editions Strange string problem in vb?

  I am currently making a program that reads the ID tags from an MP3. Here is my problem or an example of my problem. Lets say I have the artist showen in a msgbox and the song title showen in a seperate msgbox like so: msgbox(artist) msgbox(song) The msgbox will appear and show the correct info.

What I really want to know is what can cause it to not display the rest of the string like I want it t ...Show All

• Visual C# Empty C# application use almost 20mb memory

  I just started learning C# and decided to make a small alarm application, like an egg clock. And after a while i noticed the alarmclock used almost 20mb of memory when it was minimized to the systray. If i minimized normaly it went down to 1mb, and when it’s on normal form it uses 20mb again. I also noticed that its the exact same thing with a empty C# application. Why is that A small windows form with a button, textBox and timer should not ever use 20mb of memory. Hi, In addition to that, there is another factor that comes into picture: If you are observing the "Mem Usage" column in task manager, all .N ...Show All

• SQL Server De-normalising query

  OK. I know this can be done with cursors but would like some pointers on if SQL 2005 provides any more elegant solutions. Basically I have 2 tables ... TableParent(ParentPK, ChildFK) TableChild(ChildPK, ChildValue) For each row in TableParent, TableChild may have up to say 5 rows. I need to transform this into a table containing at most the first 3 ChildValues (ordered by ChildPK) of the form ChildValue1 Childvalue2 ChildValue3 Any tips on how this could be achieved by a more efficient means than cursors Thanks, Greg. I think I found a more elegant solution for you with SQL2005 First I created #tmp t ...Show All

• Smart Device Development Forms closing despite OnClosing being overridden (usually on wake from sleep)

  I've got some forms that I want to keep loaded on the PPC, and as a result, I've cancelled the OnClosing event that is caused by the WM_CLOSE message as Windows CE attempts to free apps to free memory. This seems to work well when I switch apps etc. The WM_Close is sent to the app, and the WM_Close is cancelled. The problem I am having however is when I sleep the device and power it on at a later time, some of the forms I have loaded, unload. Is it possible that a more hostile message is sent to the app when resuming the device which causes some of these forms to unload (wm_destroy) Thanks again! Appreciate any help! pocket ...Show All

• Windows Forms Setting TextBox MaxLength from DataColumn MaxLength

  I've got a TextBox bound to a column in a DataTable. I want to programatically set the MaxLength of the TextBox to the MaxLength of the corresponding DataColumn. The DataSource Wizard (surprisingly) doesn't do this. How can I do it Here's the answer private void SetLengths(Control cp) { foreach (Control c in cp.Controls) if (c is TextBox) { Binding b = c.DataBindings["Text"]; if (b != null) { BindingSource bs = (BindingSource) b.DataSource; (c as TextBox).MaxLength = ((DataSet) bs.DataSource).Tables[bs.DataMember].Columns[b.BindingMemberInfo.BindingField].MaxLen ...Show All
