View 1 RepliesJust opened the VS2010 pack I've been meaning to get round to for ages. Where is the setting to use un-docked forms in the de?I know I can un-dock each for manually but thats pants.
View 6 RepliesDid vs2008 or vb.net got some of the solution to solve properties setting of the components are same with each other?
Example: like I want to standard the datagridviews' property, each of the datagridviews' property is same with each other. but each time I create the new datagridview. I have to manually set the datagridview 1 by 1.
I'm doing an application for a school to help them keep track of student attendance and because I'm rather new to VB 2008 .NET I'm sure I'm missing something simple.see the screen shot and attached sample application showing the problem I am having.
The screen shot shows 3 open forms. I'm not able to get the value from the 3rd open form into the Student ID textbox of the 2nd form even though my messagebox shows a value is really in there.The attached application has 3 forms similar to the production application I'm writing which also includes 3 forms. Could you look at the application and tell me what we are missing to get the textbox data in the 2nd form to show up?
I've set the Icon for my forms and project, and saved. But my project's icon is still the default app icon.
View 14 Repliesi am working on a college project in visual basic 2010. in my program, i noticed at the last minute that i needed to add a "main" window. in this main window, i want to have all my other forms opened by buttons (i know how to do that part of it).
the problem i keep having is the window with the options to save the information pops up, not the main window. is there a way to easily fix this? maybe a snippet of code, because the only way i can think of is to scrap the project, start over from scratch adding my main window first, then the others.
I have a list box on my form with 2 value - "2010" & "2011". When I change the value in the listbox it should set the minimum and maximum value of 2 datetimepickers. Each time I try to change the value I get an error - for example if I change the listbox from 2011 to 2010 I get the error:
"Value of '31/03/2011 00:00:00' is not valid for 'MaxDate'. 'MaxDate' must be greater than or equal to MinDate. Parameter name: MaxDate"
If ListBox1.SelectedIndex = "0" Then
DateTimePicker1.MaxDate = #3/31/2011#
DateTimePicker1.MinDate = #4/1/2010#
DateTimePicker2.MaxDate = #3/31/2011#
DateTimePicker2.MinDate = #4/1/2010#
End If
If ListBox1.SelectedIndex = "1" Then
DateTimePicker1.MaxDate = #3/31/2012#
DateTimePicker1.MinDate = #4/1/2011#
DateTimePicker2.MaxDate = #3/31/2012#
DateTimePicker2.MinDate = #4/1/2011#

I have a panel with 5 labels and 5 listviews in it. By default they are hidden. At runtime I want only the ones shown that are needed. For example, if there are enough players for three tables then three tables should show up. I know how to make the controls visible, but not sure how to control how many are actually displayed. I also think I may have to do seperate loops and seperate the control types?
Private Sub Set_Tables()
Dim tables As Long
tables = Math.Ceiling(NumPlayers / NumPerTable)

I am having one heck of an issue with a webbrowser control I am using. As part of my job, I am working on creating a tool to automate an older system that we still use. The part that is being automated is web-based, and the group running the automation does not have access to any automation tools like QTP. In order to give them something they can use, the idea was to build an application just for them. In this application, I have everything working perfectly, with the exception of the most important part: the entry of a policy number. The policy number goes into a textbox, and then the user presses a button. A part of the automation sequence involves the use of a timer.
If I manually navigate to the appropriate page and put the .SetAttribute statement in a button action on my form, it works perfectly fine. However, if I put the .SetAttribute statement anywhere that is being controlled by the timer ticking, it does not work.So, this works:
Private Sub btnTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTest.Click
Me.wbPrestige.Document.Window.Frames("WORKSPACE").Document.GetElementById("policynumber").SetAttribute("value", "1234567")
End Sub
but this does not:
Private Sub timerLoad_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles timerLoad.Tick
Select Case currentStatus
Case Status.wait_for_retrieving
[code]....
As a note, I do not have the Select statement in the Tick action; I have it in its own little sub. However, since it functions the same way no matter where it is, and to save space, I combined everything here. Also, at the time of the timer firing and setting things into motion to enter the policy number, the page is already fully loaded, so I don't think it is an issue with that, though I could be wrong.
It does not throw an error. The "1234567" above is passed in as a string, and doing a watch on it at run-time does show that the value is actually in there. It just seems like the .SetAttribute is not registering on the textbox. I have tried a few things ranging from "what-if" all the way to "that-is-so-dumb-it-just-might-work." Nothing seems to do the trick. I have tried sleeping everything for a few seconds just to see if there was an issue there. I have tried issuing the .SetAttribute command a few times in a row thinking it just wasn't taking the first time. Since setting .Focus() didn't seem to work for it, I even went so far as using SendKeys to move focus to the textbox on one attempt and API calls for mouse clicks (to click inside of the textbox) on another attempt. As a last crazy attempt, I had the Select statement doing a .PerformClick on btnTest (which works if I navigate to the page manually).
Most of the apps I write have a base / home form and a few other forms (three of four typically) which pop up in response to controls clicked by the user. I'd like to be able to set some properties to be the same for all the forms in an app; particularly properties like BackColor and FormBorderStyle. Yes, I can manually set the individual properties for each form in the VB IDE, but I'd prefer to be able to have one line of code in the base / home form for each property along with one line for each dependent form which says something to the effect of "use the same property value as the base / home form has". Overall, my objective would be to have one single line of code in the app which, when changed, would apply the changed property to all the forms. For example, a single line which I can change to take the BackColor from Apple to Orange for all the forms ...

Dows anyone know how I can build a timeout feature into a windows forms app.
The app is event driven, but I am thinking of somehow using a timer which counts down for say 10minutes, and one the timer ticks then we time out the user.
The problem I have is how can I reset the timer each time the mouse is moved or clicked.
I got a form, another form, another form, another form, etc.And I got a quit form (Msgbox is not pretty)So, there starts a problem.I have two quit forms now, so that the user can pick the best one.The problem is that I don't know how the user can pick it. I have a quit button in Form3. I want SettingsForm have one label that says "Use the new quit dialog:" and two RadioButtons (which it has.) The Yes Radiobutton = Uses the new form, the no button uses the old one.Settings save the selection for the next session, etc.
RadioButton2 = Yes
RadioButton1 = No
Label = Use the new quit dialog
ButtonQuit = The Quit Button
I am doing a alarm system project which allows a user to select a particular alarm and test the sound. It will also enable the user to save the alarm as the prefered type.

View 1 RepliesSo I am playing around with the resize event. My form is 500 wide, my button.left is at 100. If I use:
Dim int As Double
int = button1.Left / Me.Width ' this = 0.2
'resize event
'Button1.Left = (int * Me.Width)
TextBox1.Text = (int * Me.Width).ToString
The number in the texbox is correct - proportion wise, but it won't set the button1.Left to this number. I'm sure this is because int is a Double where .Left is an integer?
I'm having trouble with setting a datagridview's cell in edit mode, or rather, to let the user type some input on load of a form (as in Excel or the like).
This is my code (after the dgv has been filled):
dgvTentander.EditMode = DataGridViewEditMode.EditProgrammatically
'(or dgvTentander.EditMode = DataGridViewEditMode.EditOnEnter)
dgvMyDGV.CurrentCell = dgvMYDGV.Rows(lastrow).Cells(TeCOL_Quant)
dgvMYDGV.BeginEdit(True)
The code correctly indicates that the cell is selected, and when the page is loaded I can still se the cell selected, but the cursor doesn't appear and nothing happens when I type.
Is there any way to create a new setting from source code instead of having to create the setting first and editing it later?

I've been searching for quite a long time how to do this. I don't know how to set the colour of a row item in the GridView (WPF) using code I don't want an example in XAML. My data comes from me loading & pulling apart an XML file. I then put it into a small class with properties and those are bound to the column to populate the data. Later, it can begin some functions on the table's data. Because this takes at some times over 10 minutes it's on a thread & I would like to colour the rows I've completed parsing depending on the result. (IE: Red for HTTP error, Orange for XML parsing error ect...)This is the GridView's XAML:[code].....
I am then parsing the data using the url column. I am currently changing the selected item as I go through. I want to know if theres something I can do to change the specific item. Let's assume I'm on row 500: I use: setSelected(i) which uses Dispatcher to safely change the selected row. Is there anything I can do to change the colour as well?
This there a setting anywhere that will enable you to open the code editor and all sub/functions etc will be "shrunk", i have a lot of sub and hate opening the IDE att the start of the day and having to minimise everything.
