• Jean LeFrancais switch constructs

  I am working with Switches and I just am wondering: Suppose a switch construct has 4 cases and the default. Also suppose the 2nd case is true. If the switch construct does not have a break statement which of the following is true Hi, C# switch doesn't support code fall-through, except when the case is empty. So you need to place breaks in your case if the case contains a code. Example: switch(myBool) { case 1: x = 100; case 2: x = 200; break; } The statement above is not permitted. switch(myBool) { case 1: case 2: x = 200; break; } The statement above is permitted and would cause a fall-through. cheers, Paul June A.

• tawm Visual C# 2003 + Framework 2 SDK?

  Hi - I hope this is the appropriate forum to post this to... I'm writing an app that is to target framework 2.0. I have an older copy of C# 2003 Standard, and after installing the framework 2 sdk I tried switching the target runtime, but it only lets me change it from 1.0 to 1.1.

Later on it should be possible to add the functionality of specifying project type and go through some kind of wizard for the selected project type.

• Art Walker 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

• CraigCody VS ComboBox missing display

  I while back I wrote a C# program using (among other things) a downdown combobox with items loaded using the .Items.AddRange() function. All works fine on my computer, but on other computers (without the VS Developer software installed), the dropdown box comes up blank. One can still select the different items through the mouse scrollwheel, so I know the data is being loaded, but the dropdown window is blank. Some of our computers have both .NET Ver 1.1 and 2.0 installed, others don't (mine specifically doesn't). The program was developed with VS .NET 2003 software. All the computers are running XP Pro, similiarily configured (though mine's the only one with the VS software), and all have the latest OS updates (I just checked). Any i ...Show All

• John Turnbull Running native code on C#

  Hello, I know the basic things how to run native code dll's with C#, bus I have harder case. The function which is in native dll requires such parameters as structures and void * pointers.

• karen_tgha 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. I realize that I have the possibility to make the entire interface internal. But that does not change the fact that I cannot make the method internal. Consider this example: internal interface ImyInterface { void f1(); } class MyClass : ImyInterface { public void f1(); } In this example it is impossible for me to declare the function f1 internal (because this will result in my class not implementing the interface). Is it in any way possible for me to make the function internal If not, why not A inte ...Show All
