Using SendMessage API Function With Masked Text Control?
Oct 21, 2010
I am developing an application that inserts text into another application. No problems at all finding handles and using SendMessage to insert text into their standard edit boxes/combo boxes/etc.My problem is that when I attempt to insert text into what appears to be a masked
text
box
(e.g. a date into a box with the format __/__/____), it does so...but the application does not recognize it as valid data.How to I format my string/SendMessage to match the mask in the text box?

I developed a little app which uses SendMessage function to turn off monitor. My friend asked me whether using the app regularly will harm his monitor. He had some issues with his mother board when he used a similar app. Is there any harm (for hardware) in using the function to do things like these?

I have wrote a function which validates a masked exit box date format. I have entered into the Mask property 00/00/0000 which on screen translates to __/__/____, great. If I get an invalid date I want to clear the content and reset the focus back giving a message box warning. [code]It all seems to work until I then try to enter a new date. The first number a press seems to push the mask characters to the right and then the rest works. So if I entered 01/01/2009 I end up with _1/01/2009.

I have created a webcam application in vb2010, when I run the app I get a run time error, please see below PInvokeStackImbalance was detected Message: A call to PInvoke function 'WebCam!WindowsApplication1.WebCamMainForm::SendMessage' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

However I need to interact with a program designed in vb from perl (yes I MUST do it this way....)
The control I need to get text from has a class TL80.C1List32.20 I believe this is a listview. I can get a handle to the control just fine.
I have access to the SendMessage function via a wrapper with this prototype:
SendMessage( $hwnd, $msg, $wParam, $lParam );
(A $ denotes a variable in perl)
The listview also has 2 child windows of class: TL80.C1List32.20_SC
which I believe are scrollbars.
I need to retrieve (but not set) the items in this listview via the wrapped SendMessage function.
I can provide any other information you'd like from Winspy++ or can probably dig it up on my own if you let me know what you need.

So I'm passing a masked telephone number in the form of (999)999-9999 to a Function that 'strips' the numbers out and puts them into a string that I then use in an Update SQL statement. So far I have the code below that of course doesn't do anything:
Function StripPhone(ByVal sPhone as String) as String
Dim i as Integer
Dim sStripped as String

If MaskedTextBox2.Mask.Substring(2) = "PM" = False Then
MsgBox("I have detected that you've put something else rather than AM or PM in the last two spaces.", MsgBoxStyle.Exclamation + MsgBoxStyle.OkOnly, "Error")

Basically I am doing a weekly assignment for unit 7 where I have to use Data bases.... I have everything going fine I used VB studio to set up most of my relationships between the Data base and VB.I have a text box called txtLast4OfSSN.Text that I need to get the last 4 of a social security number.
Now this should be simple I have another box ( a Masked Box for SSN) that has the SSN in it... This box is called m_SSN.Text....... Now I figured it would be easy, and that I could just use the Substring(7, 10) to get those numbers :*( However its not working and I am getting an error as follows:"Index and length must refer to a location within the string. Parameter name: length".Here is my complete code with my two buttons its mostly in the second event procedure that I have the code specifically for getting the last 4 of the SSN:

I am using a masked text box to format phone numbers. However, I do not want the extra formatting that gets insterted from the masked text box: (800)-555-1212
All I want is: 8005551212
But I still want the user to type it in like this (to make it easier for user):
(800)-555-1212
I am thinking I can run a replace function on it, but I am not sure what event to use. I found a number of tutorials, but not that useful for what I am doing. [URL]

I have unformatted text in my SQL 2005 database. I'm pulling it into a masked edit text box with a (999)999-9999 mask.Unfortunately, when I attempt to save the data back it doesn't work because I don't know how to get the 'masked' information back to the 'unmasked' raw data that the database wants.

When populating the data into a date masked text box for display, I am not getting the zeros in front of the month and day resulting in the date 07/02/1974 displaying as 72/19/74.
How do I insure the month and day have the correct format before the masked tb gets filled. The data type in SQL is small date and displays in the table as 1974-07-02 vS2008 / SQL2008

I have a phone (and Zip Code) masked text box on a form. I am reading data from a SQL table. If I use the code at bottom in a lost focus call no errors are thrown but I see nothing in either masked text box. However, I tried a few things to understand whats happening. I inserted a standard text box on the form and sent the Zip Code value to it and it appeared in the box no problem. Also, if I use the following code: Zip_TextBox.Text = 01940 or Zip_TextBox.Text = "12345" in the form load it appears in the masked text box just fine. So I am not sure whats going on.
The code below is in the lose focus method for a combo box on the form. It all works correctly except for the Zip and the phone numbers fields which even though I called them text boxes they are masked text boxes.
