I need to know how to do two things.
How do I make it so that no date at all is the default date in a date time picker. I noticed that the date time picker displays the current date by default.
How do I set the date to a particular date using a date time picker. I will get the date from a database and put it into a dataRow.

1 - I don't think you can, it needs to show *something*
2 - I expect you set the same property ( Value, perhaps ) that you get after it's been shown to see what was selected.

1. Are you talking about nullable datetime picker? There are a few articles here.
2. You set the datetime picker's Value property, or do a databinding.

Hello experts!
I've ran into a problem in my VB.NET coding. I've created a form with no border and is painting it with pixels-transparent PNG images using UpdateLayeredWindow. At the moment, the form is moving using the "caption" function in WndProc, the NCHITTEST thing..
The problem is, that it want to make the form able to "snap" to other forms also painted with UpdateLayeredWindow. I've already tried a lot:
Protected Overloads Overrides Sub WndProc(ByRef m As Message)<br />
Select Case m.Msg<br />
Case 512 ' mouse move<br />
<br />
If ((Me.Location.Y + Me.Height) > (frmEvent.Location.Y - 10) And (Me.Location.Y + Me.Height) < (frmEvent.Location.Y + 10)) Then<br />
Me.Location = New Point(Me.Location.X, frmEvent.Location.Y - Me.Height)<br />
'MsgBox("yes")<br />
End If<br />
Case 70 ' windows position change<br />
drawstring += 1<br />
<br />
If ((Me.Location.Y + Me.Height) > (frmEvent.Location.Y - 10) And (Me.Location.Y + Me.Height) < (frmEvent.Location.Y + 10)) Then<br />
Me.Location = New Point(Me.Location.X, frmEvent.Location.Y - Me.Height)<br />
'MsgBox("yes")<br />
End If<br />
Case 132 ' NCHITTEST<br />
m.Result = New System.IntPtr(2)<br />
If ((Me.Location.Y + Me.Height) > (frmEvent.Location.Y - 10) And (Me.Location.Y + Me.Height) < (frmEvent.Location.Y + 10)) Then<br />
Me.Location = New Point(Me.Location.X, frmEvent.Location.Y - Me.Height)<br />
'MsgBox("yes")<br />
End If<br />
Return<br />
End Select<br />
MyBase.WndProc(m)<br />
End Sub
However, this does not work (the example only includes snapping to the top of another form called frmEvent). When I move the form above the other form, it sometimes "blinks". If it doesn't blink, it will just do nothing. When I have the form where it is supposed to snap, it will first be snapping when i release the mouse.
Can anyone help me here?
Greetings..

Hello...
i need help wid user input via a table.Searched high n low,but got no solution. 
My problem: i want the user to TYPE in data into a table (or table like structure,dat looks like a data grid) and then, on the click of the save button,the data is saved to the database i.e into the actual table in the database.
for example:
name age state country
---
---
---
---
and so on 
|--------------|
| SAVE |
|--------------|
....all done at the front end,in order to simulate data entry into an actual table.
How do i do dis?????
Data grid has dat kind of structure...sadly it takes no input.
Can anyone temme how dis cud b accomplished?
Hmmm....VB.net must have some visual 'table' like control,like there is in microsoft word and excel,dat cud make data entry of dis sort possible...
there's something for a treeview,but no TABLE!!!! 
|

wid and dat are not words. Neither is temme, dis, cud, or b. We are grown ups here, we're not 7.
Perhaps if you used english when you typed stuff into google, you'd find the various grid controls. Of course, you need to write some code to stuff those values into your databaser.

I am working on a program that stores peoples data, only while the program is running thouugh. I want to create an array to store thier details. I want to store 10 users details. I have:
txtName = Their Name textbox
txtAddress = Their address textbox
txtAddress1 = Their address textbox
txtAddress3 = Their address textbox
txtPhone = Their phone number
I also want to store whats in cmbboxCar = car list combobox
I have a button called "txtStore" that will store the details when pressed, but don't know to do that.
I have a numericupdown = detnumber which when value is increased/decreased I want it to display whats stored in the current array index number. Say "5" was selected in the numericupdown, I want the details for person 5 to appear in all textboxes, comboboxes. But I want the updown to only go as high as the number of values stored. e.g. if 6 users details were stored, the numericupdown wont go higher.
Any ideas?
Thanks in advance
In the end we're all just the same

If you create a collection and insert the data, you can serialize the collection to disk and then load it again when the program restarts.
There are 100's of examples of this on the Internet. Very simple to do, just a few lines of code.

I have the array almost completed and stored array code in module (Bits of the code here):
<quote>Public txtRemainingBalance(10) As String
Public txtCustomerName(10) As String
Public txtAddress1(10) As String
Public txtAddress2(10) As String
Public txtAddress3(10) As String
Public txtRegNo(10) As String
Public txtCarModel(10) As String
Public ComboBox1(10) As String
Public txtPurchasePrice(10) As Decimal
Sub CalltxtCustomerName()
txtCustomerName(0) = "Not Defined"
txtCustomerName(1) = "Not Defined"
txtCustomerName(2) = "Not Defined"
txtCustomerName(3) = "Not Defined"
txtCustomerName(4) = "Not Defined"
txtCustomerName(5) = "Not Defined"
txtCustomerName(6) = "Not Defined"
txtCustomerName(7) = "Not Defined"
txtCustomerName(8) = "Not Defined"
txtCustomerName(9) = "Not Defined"
End Sub
Sub CalltxtAddress1()
txtAddress1(0) = "Not Defined"
txtAddress1(1) = "Not Defined"
txtAddress1(2) = "Not Defined"
txtAddress1(3) = "Not Defined"
txtAddress1(4) = "Not Defined"
txtAddress1(5) = "Not Defined"
txtAddress1(6) = "Not Defined"
txtAddress1(7) = "Not Defined"
txtAddress1(8) = "Not Defined"
txtAddress1(9) = "Not Defined"
The "Sub CalltxtCustomerName" and similar names just hold the "Not defined" text that displays when array is run.
On my third form, I have list boxes that display whats in the array in listboxes. Here is the code on the display button on that form:
<quote> ListName.Items.Clear()
ListAddress1.Items.Clear()
ListAddress.Items.Clear()
ListPostcode.Items.Clear()
ListCarReg.Items.Clear()
ListCarModel.Items.Clear()
ListCarCost.Items.Clear()
ListCarMake.Items.Clear()
Dim i As Integer
For i = 0 To 9
ListName.Items.Add(txtCustomerName(i))
ListAddress1.Items.Add(txtAddress1(i))
ListAddress.Items.Add(txtAddress2(i))
ListPostcode.Items.Add(txtAddress3(i))
ListCarReg.Items.Add(txtRegNo(i))
ListCarModel.Items.Add(txtCarModel(i))
ListCarCost.Items.Add(txtPurchasePrice(i))
ListCarMake.Items.Add(ComboBox1(i))
Now, all I want to do is on the form 1 and 2, make a button that stores whats in the text boxes and addes it to the index of the array, txtAddress1, txtAddress2 etc.. and adds that info into the next index number of the array and then clears the text boxes so that more data can be input and so on. I looked for examples, but can't find any. Any help would be appreciated.

Hi evrybody,

You cannot use the WMP to play from a stream in memory. It has to play from a file.

my problem in my programm is that i have a stream containig video or sound and i want to play it in my windows app via windows media player control .
this code can tell windows media player (=wmp) to play a file in internet
AxWindowsMediaPlayer1.Url = "some address";
this code meaning that wmp can play a video or sound streamly .
and my question is how can i play my stream when it is in memory ?
i find something about creating protocols to do something like the url passing to wmp
hope to your help.

For the second time, you can't. WMP will NOT play from a MemoryStream in your code. You MUST use a different control to do this, but I don't know of any.

Ive been searching through my ebooks and google literally for 5 hours now looking for a solution! Can anyone guide me on how to select a particular tab in a 3rd party application, either by the index number, or the tab name?
This selects the window I want to interact with:
<br />
Private Sub Button1_Click(...) Handles Button1.Click<br />
Dim Window As String<br />
Window = "PetDeviceMainDlg"<br />
AppActivate(Window)<br />
SendKeys.SendWait("%{F6}")<br />
End Sub<br />
And Ive tried every variation of this code from the MSDN (http://msdn2.microsoft.com/en-us/library/cdc8ebh8.aspx) that I can think of:
<br />
Private Sub Button1_Click(...) Handles Button1.Click<br />
<br />
Dim Window As String<br />
Window = "PetDeviceMainDlg"<br />
AppActivate(Window)<br />
SendKeys.SendWait("%{F6}")<br />
SelectTab(6)<br />
<br />
End Sub<br />
<br />
Public Sub SelectTab(ByVal index As Integer)<br />
<br />
Dim instance As New TabControl<br />
instance.SelectTab(index)<br />
<br />
End Sub<br />
When I debug, index does equal 6, but I get the error 6 isnt valid for index.
Any help would be much appreciated.

A New TabConrol won't have any pages.
Seems like you are trying to select a Tab page in another application, correct?
If so, the SelectTab(6) is executing against your application and not the intended target application.

If I take out the "new" i get the error "'instance' is used before it has been assigned a value". Im not sure why I had new in there, just picked it up from one of the google articles I think. How do I get it to keep focus on the other application? "Me." is for the VB form right?
Thanks

I think you miss the larger picture.
You can use SendKeys to send key strokes to another window.
But you can't write code in your application that executes in another window, especially if it's in another process.
Your tab selection code is running locally in your application but can't effect the other application or window.

Im going about this the wrong way then, I just want to either scroll through tabs using ctrl + tab until I hit the right one, or just activate TabIndex 9. I know it can be done because I have a program written in VB6 that does exactly what I want, using a combination of SendKeys and FindWindow. I just figured since tab index is constant that would be the fastest and most reliable way to accomplish this. I'll see if I dont have better luck tomorrow.

Are you using Vista?

Win XP SP2. I think the answer is in using the user32 API, but Im not knowledgeable enough to know what Im doing yet. My 3 hour video tutorial didnt get into this haha.
Too bad its not as simple as the script language I use... "WinActivate, PetDeviceMainDlg, Manual" Done
|
|
|
|

The reason I asked about Vista is because the VB.NET and VB SendKeys function no longer works on Vista like it used to. There are aricles out there for a replacement that does work on Vista.

Ok, since there is obviously no practical way to pick a tab, how do I go about using a loop? Something like
<br />
While "ActiveWindow" <> "GetInfo"<br />
SendKeys.SendWait("^{TAB})<br />
Wend<br />
|
|
|
|
|
Since I can see what you are seeing I'm not sure. But trying different things can't hurt.
