Function Key Form Combo Not Working?
Aug 10, 2010
I have a form that displays a graph. From the appropriate toobar button click frmGraph.show is called and it works. But when I call it from the assigned F6 function key the graph hardly ever displays. Sometimes it does display properly, sometime it flickers a one time display of the graph then it's gone, but mostly the form just draws the background but no graph. In debugging this i discoverd that putting a message box just before the call to frmGraph.show the graph will display properly everytime after i click ok in the messagebox. Anyone know how to cure this or at least a workaround that doesn't involve displaying the messagebox? This is the code with the messagebox("here") just above the call.

adding to the binding source then setting the combobox to selectedIndex of newly added row is not working.the new row is in there but it does not set the selectedIndex to the specified index. but if I run the code a second time it selects it.what can i do to make sure the combo uses the specified index?
Dim drv As DataRowView = CType(Dispatch.M8CustomersBindingSource.AddNew(), DataRowView)
drv("custID") = "999999"
drv("CustomerName") = "Select Customer"

I was wondering if there is a way to run a sub/function from a textbox and button combo.
So say you had
HTML
Public Sub XX()
I would want to be able to put XX in the text box click the button and whatever was in sub xx would run.

I started a forms solution in VB 2008, created a datasource to an access database (2010) and used the datagrid view to display the data. 3 fields in the access database are lookup fields with 2-8 values each, typed in by me, since the linking to other fields did not work. This is not working either. When I change the column to combo-box or not, those values, typed into access, are NOT showing up in the datagrid. the combo box has its drop down arrow but the value fields are empty.

In VB 2008, I have a Parent form with a combo box on it. There is a child form also with a combo box on it. I want to be able to change the values on the child form based on what the user selected from the main form. The user launches the child form from a toolbar on the Parent form. The following code is run:
[Code]...
What I want to do is if the Parent's combo box has "Red", "Blue", "Green" values and the user selects "Green", the child form's combo box(With the same values) will also change to "Green". (I do not need to change the Parent form if the child form changes.) I've tried changing the Child's combobox from the combobox's change event on the Parent form, and the code runs, but nothing changes on the child form.

I'm using fileopen() function to open the file, after doing all the works I'm using fileclose() to close the file. But when I access the file again it returns already the file is opened by another process.
Sample:
Dim intFile As Integer = FreeFile()
FileOpen(intFile, mstrFilename, OpenMode.Binary, OpenAccess.Read, OpenShare.LockWrite)
FileClose(intFile)

Loading another form increases the memory usage of the application and after closing is not combing back to normal? dispose function at formclosed event is not doing that

I have the following code which I want to run when the page first loads and then again when an update panel (asp.net) is run. Therefore I need to use function pageLoad() rather than document.ready.
function pageLoad() {
$(".zoomImage").each( function() {
$("<img src='"+$(this).attr("src").replace("-thumb.jpg",".jpg")+"' />").appendTo(".howitworksText > div");
});
};
Problem is I can only get this working with document.ready - so therefore not when the updatepanel is run.

I found the following example of how to print a root directory on the net
Code:
Sub Main()
Dim Current As String
Dim Root As String
Current = Directory.getCurrentDirectory()
Root = Directory.GetDirectoryRoot(Current)
Root = Directory.GetDirectoryRoot("")
Console.WriteLine("Current directory {0}", Current)
Console.WriteLine("Root directory {0}", Root)
End Sub
However it just causes the error "name directory not declared"

I have an array with about 10 items in it. In order to get the desired functionality I need to append some text to each item in the array in order to sort it properly. Once it is sorted I want to remove the text I added and then just display the second half of each item in the array. The sort works great, but the split function is not worrk.

I have no clue how to get ScreenToClient working. I declared the function using:
Private Declare Function ScreenToClient Lib "user32" (ByVal hwnd As Integer, ByVal lpPoint As POINTAPI) As Integer
Then:
Private Structure POINTAPI
Dim x As Integer
Dim y As Integer
End Structure
[Code] .....
What I want to do is move the cursor to 29,109 of the hwnd, not my screen (hence why I'm trying to use screentoclient).

the problem lies with "SHDocVw.tagREADYSTATE.READYSTATE_COMPLETE" I an example of it on the net and it works in the sample app but not in mine. It won't compile because it says "Name ShDocvw is not declared" and i've searched through the example app and can't find it "declared" anywhere. I had a look at the designer generated code and found
2003 - Friend WithEvents AxWebBrowser1 As AxSHDocVw.AxWebBrowser
2005 - Friend WithEvents WebBrowser1 As System.Windows.Forms.WebBrowser
what is a AxSHDocVw.AxWebBrowser? Now i've done some searching and found that apparently "SHDocVw.tagREADYSTATE.READYSTATE_COMPLETE" no longer works in 2005.

My Problem is, that I have some Buttons, Labels and TextBoxes I need to generate after the User told a number of Players. With the Code I'm using now only the last Player will have these Controls working, because they are moved - for example - from Player 1 to Player 3. how to create such a ControlArray The biggest Problem I have is, that these buttons have to have names like "1", "2", "3" and so on (or if it works somehow to read out the Index of a ControlArray the names will not be necessary).
This is the code I am using right now to generate the Controls, but as you see it won't work, because the properties will be changed when the For-Function restarts.What I need is a hint on how to get these Controls/Buttons into a Control-Array and then read out the Index-Number to use them in the Functions that are called.
Public Class Form1
Private btnTestNumButtons() As System.Windows.Forms.Button
Private Sub CreateButtonArray()[code]......

I've reviewed the other posts regarding this subject. I'm using VB from Excel and the function keys are not working. I'm running Windows Vista Home Premium with Office Ultimate 2007 Looks like Excel is running VB 6.5So, this used to work for me...I've used the debugger quite a bit. When I try the solutions suggested Tools->Options->Keyboard (after checking check-box to show all settings) when I click on the box just below "Apply the following additional keyboard scheme" the only item in the list is default. There is no selection for VB 6 or anything else for that matter.
