View 11 RepliesI need to select all the comboboxes on a form with a for each loop. I have about 19 comboboxes and I need to select each one. I tried to do
for each box as combobox in me.controls
But that gave me an error and i now tried this:
for each box as control in me.controls
if box.name.contains("ComboBox") then
...
end if
next
That selected only the comboboxes but the problem is i need to access some data that is specific to comboboxes (aka the selected item(s), if its blank) but those properties are not present since "box" is a control, not a combo box.
i have 2 labels that are 1 for minimum damage and the 2nd for maximum damage,how do i make it so if when a person clicks a button it deals damage between the 2 [code]so if i press the button it were to deal (subtract) damage in between the 2 numbers. from a label box (opponent health)
View 16 RepliesI am pretty familiar with how to use the webbrowser control. I know how to autofill forms using the getelementbyid code but I'm having a problem selecting from drop down menus.
Here is the html source
<select name="birthday_mon">
<option value="0">---</option>
<option value="1">January</option>
[Code].....
I am placing 2 of these on my form and want to do the following:
1. When the control is not Focused and the user clicks inside the control, I want to highlight all text within the control. I expect to use SelectAll() to accomplish this.
2. When the control IS Focused and the user clicks inside the control, I want standard actions to occur; i.e., the user can click-and-drag to highlight, double-click to highlight,
3. When the user leaves the control (clicks on something elsle), if the control is empty, I want to populate it with pre-defined text. If it's not empty, leave text as-is.
I'm having problems, though, with figuring out #1 and #3. I have tried Enter/Leave, GotFocus/LostFocus to no avail. With Enter/Leave, the text will highlight the first time a user enters the control, but I can't seem to get the program to think the user has "left" the control. That is, the "Enter" code will not fire again.
I also thought about using the Click event, but I don't want the SelectAll() code to fire for EVERY click in the TextBox controls.

How can i stop the same image from been selected twice from my image list

1) My program has 3 groupboxes each consisting 3 radiobuttons. Based on what is checked in the first box, and then what the user chooses in the second box, I either need to hide the 3 box and choose one option, or keep it showing for the user to select an option. The hiding is because based on the previous choices, there is only one option for the user in the 3rd box, and so I don't want to confuse the user nor waste their time. So I when the user selects radiobutton1, I need to hide groupbox3 and select radiobutton2.This is what I have previously attempted and it didn't work.
[code]...
How can I select the radiobutton using code like shown above?2) My second question is regarding scanning strings. I have 2 output strings. They either print a device or a message saying why the user doesn't get an output. At the end of the code, I need to scan through the strings until I get to a space and then store that as a string. How does one go about doing this?
I am trying to get back a single from from a EF database model using the below line of code..
Dim _classRoom As classrm = db.classrms.Select(Function(b) b.Course_ID = _CurrCourse.course_ref)
Where classrm is the name of the entity and db is declared as a new entity. What I am trying to do is select a row from the entity based on matching Course_ID which in this model is a string. So that I can later use the variable _classRoom to get other items out of the same row.. However I am getting the following error:
Unable to cast object of type 'System.Data.Objects.ObjectQuery`1[System.Boolean]' to type 'Trial_Online.classrm'.
