• Mark Macumber ** Problem with calling unmanaged C++ DLL from C# on a network drive. **

• chiquiman SQl server authentication issue in C#

  Hi Guys, I have a tool written in C# which connects to a remote SQl server 2005. Its working fine while I use "Integrated Security". However, I want to login the database using another credential instead of using the currently credentials associated with the tool. The reason for this was because not all the users using this tool have permission to access the database. So, I need sort of impersonation to allow any user using this tool to connect to the database. Is there any simple and efficnet way to do this Thanks. I don't know if you have SQL Server Management Studio, its a really good graphical tool. Use that tool and create a new database and name it say test... Create a new Us ...Show All

• fripper Reversing Rows of an Image in a Byte Array

  My core dilemma is to read each line of an image and then flip those rows bottom to top while keeping the columns of the image the same. I know that Array.Reverse() is close to what I need, but it messes up the columns. The reason why I need to do this, is because .bmp images are apparently "bottom up" and my other functions don't understand that the image data is "bottom up", so I need to find a way to account for this "bottom up" structure. The only general advice that I received was there should be 2 for loops and for each column (0 to width) do (row * linedelta + column) and swap that with (height - current row -1). But I'm still confused on how to write the code. My Code: int Line; long LineDelta ...Show All

• D_W Why can't an interface method be internal?

  When I try to make a method in an interface internal I get a compile error.  Why is this   Thanks in advance, Per Rasmussen. Charles: What do you mean by "implemented explicitly" Philip: AFAIK this approach will not prevent an outside assembly to access Func() which was my purpose. Edit: What I mean is: everybody can call Aclass.Func() as this still have to be public because of the interface. See what I mean By definition implementing an interface means that all the functions of the interface are available to everyone. The onlything that you can do to have f1 internal is to explicitly implement the interface: class MyClass : ImyInterface ...Show All

• ai_rasmussen How to read a float from a Big Endian binary file.

  I have a binary file written in big endian. Scattered within the binary file, there are 4-byte floats that I wish to read. I can't use methods like ReadSingle() since it is in big endian format. The only thing I have found to solve this is to read it in one byte at a time...reverse the order of the array...write it out using BinaryWriter and read it back using BinaryReader.ReadSingle() from the temp file. This seems to have a lot of over head...is there a better way to do this (I tried the way below but did not work) Thanks. -JRozak FileStream fs = new FileStream(openFileDialog1.FileName, FileMode.Open, FileAccess.Read);BinaryReader r = new BinaryReader(fs); float x=(float)IPAddress.NetworkToHostOrder(r.ReadUInt32()); ...Show All

• sideswipe creating id names on the fly?

  I have a need to create new tabPages. I've done it. Now I have to put some meat on them. Specifically, they will have some surfaces that I do not quite know what they are. One of them seems to be a grid. I am using a prepackaged NPlot source code for this. Everything works on one tabPage flawlessly. Now I want to generate another tabPage, and perhaps more and put those two surfaces on each and draw graphics on them. When I tried to Control.Add (object) where the object is one of those surfaces I ended up with a new tabPage generated, two grids riped off of the original tabPage and set onto the new tabPage with a perfect plot on it. The original tabPage lost all surfaces as well as the original diagram. What I want to do is do some mu ...Show All

• Garry W Simple binding to Datarow - values don't update???

  Hi, I have a loop that is populating label controls from a Datatable. If I simple bind the datarow to the labels' Text property, when I update the Datatable I expected the changes to be reflected in the label. This is true if I bind the the table directly. // this shows the correct values but they don't update when I update the data in the table ... templabel.DataBindings.Add("Text", dt.Rows[i ] , "state"); ... // when I bind directly to the table, updating the table does reflect the changes. But this option is no good as all my label controls have the same values. ... templabel.DataBindings.Add("Text", dt , "state"); ...
