• Visual Basic Add connection wizard fails with Access database

  I have the RTM version installed. I am quite puzzled at this wizard. It works fine with SqlClient. But for Access databases, this wizard completely fails. In this wizard, I only have one option to do - setting the ConnectionString. I set it to Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\path\abc.mdb, which works fine in my code. But when I click OK, it complains: --------------------------- Microsoft Visual Studio --------------------------- Format of the initialization string does not conform to specification starting at index 0. --------------------------- OK   --------------------------- And more, the Advanced button is disabled and the dialog does have the same funtionalities as described in MSDN ms-help://MS.VSCC.v80/MS ...Show All

• Windows Live Developer Forums Windows Live Messenger Sign-in Problems

  I have Windows Live Messenger 8.0, and whenever I try to log into my name, I would type my password and for some reason after I hit "Log in", another character on my password would show up.

• Windows Forms How to bind a button to an IsValid property of a derived List ?

  Hi, I'm trying to find out the best way to bind the 'enabled' property of a button to a list of objects, such that the button is enabled when all the items in the list are valid (ie. it's a "Save" button) . Now... first I thought that I would just create a new list class (derived from BindingList<T>) and give that an IsValid property (which cycled through all the items) , and bind to that. This doesn't work because the databinding on my list actually binds to the IsDirty property of the 'current' item in the list (thanks to the way databinding works with IList) . So... that being the case, I reasoned that I would add an IsValid property to my form, and bind to that. That property would delegate to the IsValid pr ...Show All

• Visual C# best way to read pipe delimited text file?

  I am trying to read in a pipe delimited file and do certain processing for each field. I was just wondering what the best way to strip out each field is - is there anything built in .Net that will easily allow me to do this Or do I just loop through and remove each field myself Also, would it be best to strip each field out into a dataset first, and then do the processing Or, do the processing while I am separating each field Or does it not matter Thanks! Saeed it really depends. You can split the entire lines read into a string[] array if you like: string[] theLines; StreamReader theReader = new StreamReader("file.txt"); theLines = theReader.ReadToEnd().Split(new char[] { '|' }, Strin ...Show All

• Visual C++ C++ delete[] operator with multiple arrays

  I'm trying to figure out how exactly the delete[] operator works with multiple arguments. Say I have some large arrays created: double *a, *b; float *c; long long *d, *e; long w = 1024, h = 1024; a = new double[2*w*h]; b = new double[2*w*h]; c = new float[w*h]; d = new long long[w*h]; e = new long long[w*h]; When it comes time to de-allocate them, I had them all in a single delete[] statement: delete[] a, b, c, d, e; Well, this appears to only be de-allocating a and completely ignoring b, c, d, and e, still taking up large amounts of memory. In order to get them all de-allocated, I had to use 5 delete statements: delete[] a; delete[] b; delete[] c; delete[] d; delete[] e; Is this how the delete[] operator is supposed to work wi ...Show All

• SQL Server SQL server 2005 table partition & Performance.

  Hi all, My question is regarding the SQL server 2005 table partitions. The scenario: ============= I have tables A & B with table A having 1 million records and table B with 2 million records. When I run a procedure which has few computations involving tables A & B, the time taken for the stored procedure to return the result set is 55 seconds. Now, I partition table A based on a column which is used in the join condition within the stored procedure and then try the same query. Still, it takes the same 55 seconds and I could not find any time differences even after going for partitioning and placing the partitions in different file groups.

• Game Technologies: DirectX, XNA, XACT, etc. Altering the Origin when using Xna

  When I use the basic Xna game template, Microsoft sets the origin (0,0) to the top right corner of the window. Is there a way to make the origin the center of the screen (without translating everything I draw 400 pixels to the right and 300 pixels down) in 2D the Origin is the Top Left, in 3D it is the centre of the screen, thats just how things are. Simplest way of having a different origin is to hold to variables for the screen offset for the centre, the best way to set the offset automatically is to use the GraphicsDevice.Viewport settings for with and height and divide each by 2.
