I have to create a form that I enter the price of gas each month over a year. I enter the price in a text box and click the enter button to send the price to a list box immediatley and use an array. I have the following code but I don't think it's working with the array correctly as it will let me enter the information but doesn't stop letting me enter after the 12 prices. I am really having a hard time trying to figure out how to set up this input for an array and make it all work.

I need to write an application that does the following, and I figured it was a good opportunity to write my first VB.Net application:
1. Get the list of fixed disks in the computer
2. For each disk, recurse through all its directories and sub-directories looking for filenames that match a given regex (eg. MyFile.d{3})
3. If found, hash this file to get a unique ID, eg. MD5 (just to check if this file already exists elsewhere)
4. If this file hasn't already been seen elsewhere on the disk, copy it to a central directory

View 6 RepliesAt the moment I have created an AutoTyper but can not get it to function in the way I want it to. I want it to have the option of choosing whether or not the enter button is pressed after the text is sent. Currently by changing True to False I can make it either send the text or send the text and hit enter. However I can not make it so it has the ability to do both.
Here is the code I am using:
Dim CheckBox1 As Boolean
If CheckBox1 = True Then
SendKeys.Send(TextBox1.Text)
SendKeys.Send("{Enter}")
Else
SendKeys.Send(TextBox1.Text)
End IF
Ok i have used
My.Computer.Keyboard.SendKeys(TextBox1.Text)to send the letters i want my program to send but i need it to press enter after i think it will use something like this
My.Computer.Keyboard.SendKeys(TextBox1.Text & Send.Enter) or something.
We have a multi-line control that we are attempting to prevent the Enter/Return key from being used to create a new line.Strangely enough, "AcceptsReturn" as False does not prevent this.So we added the following:
Private Sub txtAddr_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtAddr.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(13) Then
e.Handled = True
End If
End Sub
This works fine, however one of the QA people discovered hitting Control + Enter still puts in a newline.How would we prevent this?And why does AcceptsReturn being False not work as it appears it should? What is the intended purpose of it?

I cannot seem to successfully send the Enter key to a webbrowser control using .net. I can succesfully send postmessage Tab key and it tabs through the links and controls, but it does not click on the link when I send Enter key.The website I am opening has frames, and due to the cross frame scripting policies microsoft forced into the IE control , I cannot retrieve the links from the IFRAMES on the page. So my alternative thinking is to use Tab keys to get to the link and then press Enter.

View 10 Repliesi have been looking for a way for my application to 'safely remove hardware' or to eject the USB key specified, the application detects the removal and arrival of new devices but i am stuck on being able to eject them. So far my research has lead me to using setupapi.dll and CM_Request_Device_Eject and i have declared
Private Declare Function CM_Request_Device_Eject Lib "setupapi.dll" Alias "CM_Request_Device_EjectW" (ByVal dnDevInst As IntPtr, _ ByRef pVetoType As PNP_VETO_TYPE, ByVal pszVetoName As IntPtr,ByVal ulNameLength As Integer, ByVal ulFlags As Integer)

Public Function EjectDevice(USBDriveLetter as string) As Integer
'TODO USE CM_Request_Device_Eject() to eject the drive
End Function
I found pinvoke.net: cm_request_device_eject (setupapi) this info on pinvoke for CM_Request_Device_Eject() but i am clueless on how it works and the vb.net section looks portly documented...

View 2 RepliesI have been using the combo Box keypress event to capture the enter key when it is being pressed by the user within the combobox. The combo box style I am using is Drop Down. When there are no items in the combo box list the keypress event will capture the enter key. When I add any items to the list portion of the combo box the keypress event not longer captures the enter key. How do I capture the enter key when the combo box has items in its list.
