• Visual Studio Express Editions How to detect serial device attached to a computer

  How to detect a serial device when it is attached to the system. Solution should be in VB.NET Sorry, but where do you detect whether a serial device is connected or not, which is what this thread is about As I see it, you just open a port and then start sending. If no device is connected you will never know except that of course the dial up will not work. ...Show All

• .NET Development Stopwatch class not found in System::Diagnostics ?

  I am using VC++ 2005. In several projects that I have created I have never had this problem but now that I created a DLL project (used the Win32 wizard), I am having this weird problem where the System::Diagnostics namespace shows up a few namespaces and classes, but not nearly all that belong there. For example, the CodeAnalysis namespace is shown, then ConditionalAttribute, DebuggableAttribute, Debugger, and so on until SymbolStore, which is the last namespace/class listed. No Stopwatch and many other namespaces and classes that should be there. What is wrong It must have something to do with the project settings but I don't even know where to look to find the missing namespaces and classes. Any idea Thanks. Kamen Sounds like y ...Show All

• Windows Forms Need same event handlers for all controls within a container control

  Hello, I need ideas how to solve following: I have a UserControl containing several Labels and Panels which provide static information to user. The whole thing shall act as a single component when it comes to handling mouse and/or kbd events, i.e. user input. That means that wherever the user clicks it, the same event handlers or popup menu shall be invoked. If a kind of transparent panel covering the whole UserControl and capturing all input events could be achieved, that would be a solution, however I don't know if that's possible. I don't wish to specify all the same event handlers for each label and panel inside the control as that makes designing less comfy and it's about to forget setting all the handlers properly anyways. Any ideas ...Show All

• Visual C++ converting text from a text box to a int type

  I want to use numbers that the user has entered into a textbox by converting them from their System::String form to an int data type. I was wondering how I could go about this with a little and as easy to understand code as possible. Thxs :) I changed the value data type in the example (bool) to int, and this was when it was returning the value... My code that im having the bug with is: int value = 0; int x = Int32::TryParse( this ->min->Text, value); int y = Int32::TryParse( this ->max->Text, value); this ->Labelx->Text = Funcs::Maths::Random_String(x, y); I want to convert the 2 values in the text boxes and use those values for a random number, but because the value that is return ...Show All

  I am currently playing with the labs and in Excercise 3 of Lab01, it mentions adding the ExpenseLocalServices.dll from the resources/bin folder. I have searched the Lab folders and can find no such file, especially in the given location. Obviously, there is something I am missing in all this.

• Visual Studio Team System Using dropped testfiles for reporting???

  Hi We are running web tests during our dailybuild of our projects. These files however consume a large amount of space space (several hundred MBs per product and test run) so we have set up a task to clean them up periodically. We also move them from their standard drop location to make them more easily available for the test team. However after doing these changes our progress reports have begun losing all test data. It seems that the reporting engine is actually expecting the test files to be kept and to be positioned at the standard drop location. We get this in our event log: Detailed Message: Encountered an exception while deserializing test object data for test run cdf4c5b0-5923-4ef6-81b8-a4337f816e12. Attempting to continue ...Show All

• Windows Forms How to calculate the coordinates of text-entry fields in pre-printed forms?

  I would like to write an application in C# to collect data from users and then print them on pre-printed forms (examples of pre-printed forms: visa application forms, employment application forms, social insurance application forms, etc...). The forms have hundreds of text-entry fields. What is the best way to print the data on the forms I guess I have to calculate the coordinates of each text-entry field to do printing. If so, what approach would you recommend By the way, is C# a good programing language to write this type of application Is there any other programing language that you you would recommend I am pretty new to C#, so I don't mind switching to another language if it's better suited to my need to write the application.

• Visual Basic Complex Auto Update Program

  I've written simple auto-update logic before so that the version number of the program is compared to a version number stored in a web server txt file. What I'm going after now is more along the lines of programs that have lots of files that might be upgraded. This could mean that my web server text file looks like: primaryapp.exe, 1.5.0 secondaryapp.exe, 1.3.2 mainapp.exe, 1.1.0 mainapp.dll, 1.0.2 When the main application that contains the updater logic runs, it needs to compare the version of each of the above files on the computer against the number stored in the web server file. I know how to reference the version of the program that I'm running but I don't know how to grab the version numbers of other programs. ...Show All
