Make The Buttons Code Work With The Help Of Combo Box Category
May 17, 2012
The combo box will show the category. Suppose there are 2 categories A and B. When we click on A then the code given inside 4 buttons should work. I tried in this way ,I checked the condition of selecteditem based on that added all 4buttons sub code. But it shows blue underlines.
I did in this way: If ComboBox1.SelectedItem = "A" Then Private Sub Button1_Click....
[CODE]............
Like this I have used 3 more buttons. How can it be done?

I'm attempting to bind a combo to a collection of objects:
Dim t As New TradeOrderStatus()
Dim ts As List(Of TradeOrderStatus) = t.GetStatuses
With Me.cboTradeStatus
[code]...
This works fine and I see the list of items in the combo. However when I try to set the SelectedItem of the combo to one of the items:
Me.cboTradeStatus.SelectedItem = Trade.TradeStatus
nothing happens. Trade.TradeStatus is an instance of the class TradeOrderStatus and all the necessart statuses are visible in the drop-down list. The SelectedItem remains as Nothing (or as the first item in the list if I omit the .SelectedItem = Nothing line from the binding code).
Debug.Print(CStr(Me.cboTradeStatus.Items.Contains(.TradeStatus)))
also returns false.

I am currently working on an UI form using Visual Studio 2008 - Visual Basic .Net what i find weird is that when i tried to execute my form using the button click function, it doesnt execute until i restart the form.
Here's the situation is like:i have an openfiledialogue [Open button click] to search for a file.After DialogResult.OK is executed, the textfile chosen will then copied to another working directory. The file name will appear onto a textbox1 There will be more than 1 textfile chosen.After all the relevant files are chosen with the file names on textbox1, an OK button click will be clicked to write the file name into a *.bat file.BUT before the OK button is clicked, the user have to select from the radio button which category they want the file name to save into. EG: Country, Cities, Period.Once the radio button is selected and the OK button is clicked, a .bat file will be saved into the working directory.The next move will be the crucial button which is what this UI is created for. A data CRUNCH button is created to execute the .BAT file which was generated earlier on with the [OK buttonclick].The command used

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

I am a bit stuck with coding my save button and combobox.My entire form is ready, database is linked.All fields from DB are linked to their textboxes on the form.But i just ran into a big wall which i cant seem to break down.My save button, which is used to save the content from all the textboxes on the form to the access database refuses to work.The other this is, i want to use a combobox on my form to view the already saved entries in the access database.I think a combobox works for that, but i am not exactly sure how to pull that one off.

Create an application that allows the user to select or enter into a combo box the number of days a person will work, and calculates the total amount of pay she will receive over that period of time. Salary is one penny the first day, two pennies the second day, four pennies the third say, and continuing to double each day.
The combo box must list the following items: 30, 180, 365, and 1000. Must be the default drop down box. Use a validating event procedure on the combo box.
The program should go through a loop once for each day, doubling the number of pennies with each iteration of the loop. You will need a running totl of the number of pennies that you add to with each iteration. To calculate the total amount of pay, multiply the total number of pennies by .01 and show the result in currency format.

I have a piece of software with two tabs, inside each tab there are buttons (the user can add the buttons when they want). when tab1 is full tab2 should start to fill. I currently know how many buttons fit on the screen so I just say something like if buttons > 150 then start to populate tab 2 The problem i have now though is if the resolution is changed then a different amount of buttons can be displayed. so if I put my screen to 1280x720 some buttons are left of. I was thinking of detecting the resolution and then using different cases for different resolutions but this seems very inefficient im wondering if there is a different way?
