I have just installed VS 2010 Premium on my Windows Vista Machine. I've noticed that in VS2008 when I typed for eg " Public property MyProperty() as string " and pressed the enter..I was getting automatically the expected result. Meaning by that , that VS2008 was generating for me the rest of the code. [code] In Visual Studio 2010 I am not getting this anymore. What happened ? Is this feature still working in VS 2010 ?

View 10 RepliesI am trying to do simple insert, update, delete, select statements within VB .NET to access a MS Access database. I have tried all kinds of solutions offered on the web and while the code seems to work, no rows are inserted. Also, I have tried, unsuccessfully, to use the Try/Catch to see if there's an error with no success. I have attached the versions of VB .Net and MS Access I am using: Here's the code:

I have a richtextbox And I have programatically added lines of text to it...I would like to not be able to delete the text I have added, but add more text after. So far I've tried a timer to refresh the text in the richtextbox so that it couldn't be deleted but I couldn't add any text after..
View 4 RepliesIm creating a "Deal or no Deal" game , heres a pic of it so i can explain this abit better.
All images on the form are pictureboxes. The boxes in the middle are all named box_1, box_2, box_3 etc.
What my code is currently doing is , when i click a box it randomally selects an image from an imagelist. All images in the image list have all the amounts that are displayed on the main form. So if for example "€100,000" is revealed when i click box 1 i want the picturebox on the form labeled "€100,000" to hide.
This is the part that im having problems with. The first time i select a box the image will display and the matching figure will hide. And from then on it will display the images when i click the boxes but wont necessarily hide the correct image (matching the one thats in the picture box)
Really hope someone can spot a flaw somewhere , because its driving me nuts now. Here are box_1 and box_2 codes. And also the project is attached if you would rather have a look to see for yourself whats happening.
Private Sub box_1_MouseClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles box_1.MouseClick
MsgBox("Are you sure you want to choose this box ?", MsgBoxStyle.Information)

or I could do it another way, but how can I check the index of items in a my.setting string collection? like if I want to get the text of index number 3 how do I do that?
I am using Microsoft Visual Studio 2008 with VB.NET, and in class we were assigned this project: A procedure should calculate a 2% price increase on all red shirts, but a 1% price increase on all other items. In addition to calculating the price increase, the procedure also should calculate the new price. You can use the variables strItemColr, strItem, decOrigPrice, decIncrease, and decNewPrice. Format the original price, price increase, and new price in the lblOriginal, lblIncrease, and lblNewPrice controls, respectively.

I just wanted to know if it's possible to get an if statement to accept two strings into the same text box. An example of my code so far is below: (although please note that the program does not accept the strings after the "Or" boolean)

Okay I need two blocks of code for each of these:[code]Now both of these are under the if statements checking if the startsWith or equalsIgnoreCase check boxes are checked.

The packages available are VIP, excursion and restaurant. The price will also depend on the cruise length (7 or 10 day). I am wondering on which format to use, and if I even need to use if statements, how to make this statement true,
