I have looked at many of the tutorials, however, using 64-bit windows vista home premium using those examples, it doesnt seem to work, however, I don't have other computer to test on, is there a good way to do what GetAsyncKeyState does on my system?

View 3 RepliesI am constructing a search function in a class to be used by several of our asp pages. The idea is simple, take a search term from the user and query the database for the item. Currently I am doing this the wrong way, which is vulnerable to SQL injection attacks (and ELMAH is in there to save the day if something goes wrong):
[Code]...
The problem is since I am using a like statement, I need to be able to have % on either side of the search word, and I can't seem to do that with '%:searchterm%', it just gives an error of ORA-01036: illegal variable name/number.Can I parameterize but still have my flexible like statement be a part of it?
Any links to good descriptions and/or tutorials (with VB.net 2008) on OdbcDataReader? I tried, but didn't find many. MSDN is not such a good help in this case.
View 1 RepliesMy Intent:I am developing an application for myself which will take a series of keycodes pressed by me(even if my program is not in focus) and execute commands associated with it.It is basically like developing hotkeys.What I Have Tried:I have searched well and tried to implement GetasyncKeyState() in my program and it works well....but the problem is, it tells if a certain key is pressed but not which key was pressed last, which is what I want........I need to know which key was pressed so that I can make a word out of it and check if it equals my predefined names to execute the command, something like this:
Dim word = lastkey
word = word + lastkey
if (word = "startnotepad")
[code]......
I have a really annoying problem. I use GetAsyncKeyState() to determine if a key was pressed or not.Unfortunately, that event fires as long as I hold down a key. Is there any way to check if a Key was released?

[Code]...
I am trying to input the function key that a user has selected from a ComboBox (containing the function keys F1~F12 as options) into the GetAsyncKeyState(). However, since the ComboBox_StartHotkey.Text is a string, it cannot be converted into Long data type needed for the GetAsyncKeyState() function. I have tried Conversion and Parse Methods but what I try doesn't seem to work. Anyone know how to effectively convert a String (such as F6) into a Long data type for using in the GetAsyncKeyState() function in this case?
I used the tried to use the ItemData property to hold the Key Code representing the Function Key.

im trying to make a program that only listens to a few keys that the user presses, and if one of them is pressed, it carries out a specified command.for example, right now,i found a keylogger that could carry out my command, but id rather use something else if possible. right now, i have a timer running this:
For i = 1 To 255
result = 0
result = GetAsyncKeyState(i)[code]....
Then, in the textbox1_textchanged, i search for like if textbox1.text.contains("M") or something.problem with this, is im pretty sure its a keylogger, and i dont want to have to have that. also, it does not work in vista.
Found a solution! (should have researched more throughly!)

View 2 RepliesI realize that this would mean a third-party component and I've looked at a few. Does anyone use/know of a component that they would recommend to get reliable, quality Word to PDF conversion via a VB.NET application?
Anyone know of any cheaper options that will do a good job? I tried a couple of cheaper RTF to PDF convertors, saving the Word doc as RTF via the app but the PDF they output lost formatting on Word tabs, table of contents, page numbers, etc. Not good enough.
Otherwise, I will have to tell the app users they will need to convert the Word doc to PDF themselves (unless they have Word 2007 and pdf add-in which I can probably offer as an option).
