• CarlaC Questions about enums

  Is it possible to do the following: I have a combobox with the selected item "Item One". I want to insert all the objects in enum Item_One to a listbox. Is it possible Say, Dim t As Type = GetType(Item_One) For Each s As String In [Enum].GetNames(t) ConvertFrom.Items.Add(s) Next But I want the GetType to be whatever the selected item is in the combobox. So if the item selected is "Item Two" then I want Dim t as Type = GetType(ItemTwo) I know I can use select case but that would be huge as my combobox has many entries. Thank you. You'd need to use reflection to do this. This is a strange request tho, what's the design that requires you to do this I will try to explain ...Show All

• eginde Arithmetic overflow with signed byte

  I have an expression that returns 0xFA. I want to display it not as 250, but -5. I used CSByte(expression) but I get an arithmetic overflow. Any ideas how to fix this Thank, Troy L Well a signed byte can only store up to 127 so that's why you get the overflow. How about Convert.ToInt32("0xFA", 16) - 255 Well basically I read a file and grab the byte at a specific offset. If it is greater than 7F then it is negative, else it is positive. So if I used your expression and the value was 0x32 (positive number) and subtracted 255 wouldn't it give me a negative result Dim ReadByte As String = "0x32" Dim Conversion As Integer = Convert.ToInt32(ReadBy ...Show All

• NeedSomeAnswers Classify and manage may be a solution.

  Hello, I have some 100+ VB applications doing small jobs like reformatting files, logging events etc. These applications are spread across several servers. Does anyone know of a good, existing tool to manage all my applications on the various servers in one single view, ie. monitoring, version control etc Cheers, Eystein eystein, Firstly, you had better classify your so many VB applications. For example, reformatting files tool is related to the system management while logging events refers to system or database management. Moreover, you have some certain applications which are spread across several servers. In order to such kinds of application, maybe you have to search several too ...Show All

Take this code: wait actually youre right i get an error when i enter something that does work thats weird, because before i used any case expressions it worked just fine so i should take out the integer parse from select case Haha I figured it out I should be using Case Is how dumb of me...

• Muhammad Essa How do I copy bitmap data to a buffer?

  I have an application that displays some images using PictureBox. There is a requirement to toggle between colour and monochrome or grey-scale versions of the image, so I've created a class derived from PictureBox that contains extra bitmaps that hold the various versions of the image, and then when the user switches between them, I just assign the relevant bitmap to the PictureBox. When the image is first loaded, the application generates the monochrome and grey-scale versions from the loaded colour version. This is where the problem lies. For each version of the image, I make a clone of the original, and then loop through X and Y, using GetPixel and SetPixel to change the colour based on a conversion formula. That also works ok, b ...Show All

• Mark Visneskie MenuStrip and StatusStrip update problem in VS2005

  Hi, I have a program with a main window (MDI parent). This window has a MenuStrip and a StatusStrip. The MenuStrip has some items disabled and enabled depending on who is using the program. The StatusStrip shows the current user. I public subroutine is used to update both the MenuStrip and the StatusStrip. If the update subroutine is called from the main window (for example by clicking on a menu item that calls the subroutine) everything works just fine. I have created a login form. This window calls the update subroutine in the main window to update the MenuStrip and StatusStrip before it closes itself. The problem is that the MenuStrip and StatusStrip is not updated! If the Immediate window is used to look at the properties of t ...Show All

• Matrixchyah MDIList property missing?

  This could just be a case of me doing something wrong, but I can't seem to find the MDIList property anywhere for any items in the MenuList control. I've searched all over the 'net and the MSDN forums/helpfiles and cannot find anyone else who seems to have this issue. The helpfile states the changes from VB6 to VB.NET, and lists the MDIList property. Using VB 2005 Express, by the way. Is this a limitation in the Express version Is it because it's a beta I'm really confused by this, so any help would be greatly appreciated. Thanks! I think I found the solution to this problem, the instructions given in the MSDN walkthrough for this are incorrect.  To define which of your menu items will be the 'Window ...Show All

• Mystret Changing ConnectionString at runtime

  In my application, i am not sure where will be the database. So i thought to put the connection string in app.conf file. So that i may read it runtime and create connection. Working good. But what if i have to change the connectionString define in app.conf at runtime It may not be necessary that i must use app.conf, you people can suggest me one better approach so that i may not be dependent on databasestring. It could be created/change at runtime. Hi Actual user scoped settings are not stored in the app.config file. This file will contain the default initial value for the setting only. When you call the Save method, user scoped changes are stored in a config file located under the user's application data directory, and this ...Show All

• Gerhardo Fixed Width Text File Into SQL Database

  Any ideas on how to import a fixed width text file into an SQL database Write a conversion application which reads the values in from the text file. I'd suggest looking at the textfieldparser class http://msdn2.microsoft.com/en-us/library/zezabash(VS.80).aspx Then you can use ADO.NET to execute a Insert SQL Statement using the values read in from the text file. The following shows how a simple ADO.NET command object can be used to execute a SQL Insert Command http://samples.gotdotnet.com/quickstart/howto/doc/adoplus/ExecuteCommand.aspx Thats just the general idea of how to implement a solution.      Basically its breaking it down into two actions reading a line from the text file and updat ...Show All
