I've got a program which sets focus to a web browser, selects all and copies to clipboard. all of this works.my problem is pasting from the clipboard. I want the text pasted into a new file which I can create and open programatically but when I place clipboard.gettext in the parenthesis as the string to send to the file, nothing happens. there's no error and nothing gets pasted to the target file.i've confirmed the copy on the windows clipboard viewer just can't get it to write it to the file. (also tried just setting a textbox's text property to clipboard.gettext for testing purposes but it still does nothing)
View 1 RepliesIn my application I am selecting a folder path and then asking the user if he/she wants to display full path or file names only.
My problem arises when I want to insert the results in a datagridview. The datagridview has 2 columns:
column1 ----> shows file name
column2 ----> shows file size in MB.
with the below code I get the file name and then the file size on the same column one after the other
I want to show as follows:
File Name Size (MB)

Seanie.bmp 0.8
What do I need to modify in order to achieve this?

View 1 RepliesIt appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]

Currently, I am try to get the email addresses that have been saved or stored by the user of the computer. This isn't the emails that the user has sent or received, or the contacts he/she has in his address book. Just simply the email accounts that have been accessed from the computer.I know that there are some locations stored in the registry that have the email account. The email addresses that are used on the current computer. I just can't seem to find them on my computer.I am not sure if the registry is the only place to find it or if it stored on the web browser such as internet explorer or google chrome.
View 1 RepliesI am writing an application that connects to a specific com port. This com port can change depending on how many physical ports are on the PC, and if other USB devices have installed com ports before this one.
I have the communication to the com port all working great, but I need to get the com port description not just the "COM#" which is all I currently get.
I found in the registry where the description is stored but am having trouble doing what I need.
In this key:
Code:
HKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4D36E978-E325-11CE-BFC1-08002BE10318}
there is a varied number of sub keys. The are numbered 0000-NNNN depending on how many ports you have. Inside each of these keys, there are multiple values, although I am only interested in one or 2 of them.
My problem is, that I do not know how to get a list of the subkeys (the 0000-NNNN keys/folders) from the original key I posted. I have looked through a few registry tutorials, and I can view the default value in the listed key, but I could not find how to list the subkeys of the listed key.
Does anyone have any sample code they could share that shows how I can get a listing of subkeys, and then run through those subkeys checking for a specific value in one of the strings contained in the subkey?

I've got a .reg file and I want to add it to the registry when the user clicks a button. I've been searching the forums and I've seen allot of ways to do it without the .reg file, instead taking the values and putting them in the correct syntax, but I already have the .reg file and it would take far too much effort to place all the values in the correct syntax (The amount of values is huge). What is the code to do this? Do I have to somehow add the .reg file to the project?

View 3 RepliesI have a section of code that will compile perfectly using VB Studio 2003, but it throws a InvalidCast Exception under VB 2005/2008. The code throws an Invalid Cast exception at KeyHandle = e(field.GetValue(KeyToMonitor) line below, and as far as I can tell it is because the variable Field is passing the string Microsoft.Win32.SafeHandles.SafeRegistryHandle rather than an integer. Is this because of safe keys in VB 2005 and 2008?
how to call the handle of the registry key opened in a way compatible with Safe Keys? I'm using the code to notify when a registry key is changed using RegNotifyChangeKeyValue.
Private Function WaitForChange() As Boolean

Normally, that exception is thrown when an object's value is Nothing. However, I've been through each subkey manually and everyone has a name. The only one I could think of that doesn't, are the (Default) keys.
The issue is that I can't seem to figure out how to loop through the subkeys and check if they're nothing. If I create a loop and call ".GetSubKeyNames() to check if they're Nothing, I still get the exception because it attempts to get the names before I can even check them.
