I came accross the code below in a book. I prefer displaying my data in Winforms instead of the Console which the boook uses but I have little understanding of console codes and how to convert them to Winforms.[code]....
View 14 RepliesCould i Create a windows forms application that would have a console application form I'll use an example: say i was creating an application that would need some text written in the command line. i create the windows forms application because i want a GUI for the start page. then when i click a button, it should open a console program that is inside the windows forms application (not a seperate project)
View 7 RepliesI understand that I cannot use the System.Console to output information from a Windows Forms application because the standard input, output, and error streams are not run through the console in winforms apps. But I can't seem to find any documentation on where the standard input, output, and error streams are being directed to! Basically, I have a winforms app that accepts command line arguments and can be run in batch mode, however, I just want to direct some feedback to the user based on whatever method they're accessing the program. The app is used to redirect a client-server application from one server to another. In some instances, the user does it by hand (with a mouse), and other times they're doing it in batch mode (using SAS, command shell, VBScript, etc...). In those instances, I'd prefer NOT to use MessageBoxes because it will kill any processing they're doing.

Well I'm working on a kind of GameGuard for my private server. Ok so, I want to loop a code, I dunno if I should use Console or Windows Form Application...I dont know how to explain but I'll try doing my best to make this understandable. Ok so I want to make something that will loop this code until the console itself is closed. This code below would simply kill the windows name "Cheat Engine" program if its opened.[code]But If I use a console application, How can I make this code loop every 5 second or so? What would I need to add in this simple code to make it loop every 5 seconds and until the console is closed?

Is there a way to automatically resize a windows form to fit a smaller display? I created a program on a computer with a 12" display, everything works fine. However, when I load the same program on a computer with a 8" display, I am not able to view all the contents on the windows form. Is there a way to correct this without manually resizing all the contents on the form?

I have a hashing method whose operations depend on input to the function. Profiling the program has shown that too much time is spent evaluating this hash method. I want to try changing it into an expression tree, so the inner loop checks can be done once.
Here is a simplified version of the function (I undid some obvious optimizations for the example, and took out any input validation):
Private Function Checksum(ByVal inputValues As IEnumerable(Of UInt32),
ByVal declarations As IEnumerable(Of String),
ByVal statements As IEnumerable(Of String)) As UInt32
Dim variables = New Dictionary(Of Char, UInt32)
[code]....
I want to create a function which takes the declarations and statements and outputs a specialized expression tree representing a function which takes an IEnumerable of UInt32 and returns a UInt32.Follow-Up:I succeeded, and the speed-up was ridiculous (an order of magnitude). The main things I had to learn where:Use Expression.Lambda and Expression.Compile to get a delegate you can actually use.The Expression.Block factory method has a 'variables' parameter you (essentially) use to declare locals.Expression.lambda has 'parameters'.If you call Expression.Parameter twice, you're dealing with two different variables (even if their name is the same)! Store the result for later usage. Same for labels, etc.The result of a BlockExpression is the last expression in the block.
I am using VB 2010 and have the following code written in C that is used to access some PDF properties. translate this to VB?

I have a line of C# code and can't translate it correctly. 'myString' is a string and 'a' and 'k' are both UInt:a += (uint)(myString[k + 0] + (myString[k + 1] << 8) + (myString[k + 2] << 16) + (myString[k + 3] << 24)); Translators for VB suggest the following but I get "Operator '<<' is not defined for types 'Char' and 'Integer': a += CUInt(myString(k + 0) + (myString(k + 1) << 8) + (myString(k + 2) << 16) + (myString(k + 3) << 24))

I work in IT in a firm that are rolling out a time management application on all PCs. In order to clock in/out a user must log into the application and click clock in/out. I want to build a very simple application that when a user goes to shut down or log out of their PC, a windows form will pop up asking them if they they want to clock out of the time management software (a reminder if they have forgotten to clock out and are heading home). On the form there will be two buttons, 'yes' and 'no'. If they click yes, the system shutdown or log off will be halted and the time management software application will open automatically. If they click no, the shutdown/logoff will proceed as normal. I just need to know what i need to do to get the system shutdown/logoff to stop until either button is pressed and to stop totally if the 'yes' button is pressed. I am able to get the Time Management software to run on a button click but just not able to halt the shutdown or logoff?

As a part of a booking system I need to produce for my module, I have to create a login form that connects to a Microsoft Access Database. So far, I've created one that works without error, but it lacks certain functionality I can't wrap my head around.
I have a 'Login table' in my database with three fields: 'Username', 'Password' and 'Manager?', the last of which uses a 'Yes/No' datatype. Currently, the system can check whether or not the details are held in the database, and if so, it will direct the user to a different form.However, is it possible to have it so that the system can check what the database record has for the 'Manager?' field, and to direct the user to a different form accordingly?
