I’m using Visual basic to code a program tat is going to be used in conjunction with the company I’m working for's software. this will then return some data and is displayed in several (note not just 1 but in 5 different) text fields. but heres the hard part. i have an open notepad document untitled (its unsaved at the moment) and I want to past the data from the text fields into this open notepad. So far I have managed to output to a pre-safe .txt file which can be opened later and I have managed to copy all the information to clipboard to be pasted manually later (it was tricky to find out how to put a carriage return at the end of each field but i found the solution by using vbCrLf). but what I’m looking for is 2 things. first when i press the button i want it to copy and past the data straight into the notepad program with out any further intervention and second I want to try and us the tab command instead of the carriage return. Because later I want to use another program rather than notepad called HEAT. in this program ill be taking address lines 1 to 5 and so when the past command goes in it will put line 1 in first then tab to the second line to be pasted and then tab to the third line and so forth. but this is keeping in mind that the curser in HEAT is in the right place to start with.
so far hears my code for the button. When the button is clicked it will take the text of all the field label and then put them into a variable. this variable is then copied into the clipboard.
*********
Private Sub Command1_Click()
Dim alladdress As String
alladdress = ad1.Caption + vbCrLf + ad2.Caption + vbCrLf + ad3.Caption + vbCrLf + ad4.Caption + vbCrLf + pc.Caption
Clipboard.Clear
Clipboard.SetText (alladdress)
End Sub
*********
I know real easy this bit 
but is their any one out there that can help me with the hard bit. Thanks

P.S some one advised me to look up sendkey on msdn but its not installed on my computer and the website is not much help

I doubt SENDKEY will help. It is not synchronous with running code so you can't easily control when the key gets sent, and it can only be sent to the active window. At least I've tried many times to get SENDKEY to work and have had minimal success...
About the other part I don't have much advice.

I am writing a Windows app that is specific to a user so we will be connecting to a SQL Server database. I am having the hardest time finding what to do with a connection string in this circumstance.
I can encrypt the string and store it in the app.config, I already am doing that but I have to store the key somewhere that I can get it back out. I know that storing straight strings in an assembly is risky since it doesnt take much in order to see them, so what can I do in this situation where this app will be installed on various machines?
So to ask a direct question, how can I store the connection string where I can get to it but dont have to store an obvious string in the assembly? If I have it installed into the registry, it is still straight text in my install package, if I encrypt it then the key is still straight text in my assembly, and Ive read some articles about DPAPI but that doesnt sound like exactly what Im looking for.
Please help,
Cleako

As I'm sure you know, there is no such thing as perfect security. In most cases all you need to do is figure out your target audience and what level of security will sufice for your purposes. It usually take to figure out something that will keep *most* hackers out.
This is a first and simple step you could take to further secure your connection strings. Encrypt them and instead of storing the key as a string in your code, obfuscate it a little bit. I'm going to give you a simple example of what that means but you can derive and go nuts with it.
let's say you have the following key "mypass123".
Dim i As Integer ' A counter
Dim str(9) As Byte ' This array will store the ASCII codes of the characters in the key
Dim keyLength As Integer ' This will store the keyLength
Dim keyString As String ' Variable used to store the key at the end, as a string
str(0) = 109 ' ASCII code for "m"
str(1) = 121 ' ASCII code for "y"
str(2) = 112 ' ASCII code for "p"
str(3) = 97 ' ASCII code for "a"
str(4) = 115 ' ASCII code for "s"
str(5) = 115 ' ASCII code for "s"
str(6) = 49 ' ASCII code for "1"
str(7) = 50 ' ASCII code for "2"
str(8) = 51 ' ASCII code for "3"
keyLength = 9 ' manually specify the length of the key
' Load keyString with the key, by appending the characters of the key
keyString = ""
For i = 0 To keyLength - 1
keyString = keyString + Chr(str(i))
Next i
' Now you can use keyString as the key to unlock your connection string
obviously you can improve the method of obfuscation even further. Here's an example:
str(0) = 109 ' ASCII code for "m"
str(1) = str(0) + 12 ' ASCII code for "y"
str(2) = str(1) - 9 ' ASCII code for "p"
str(3) = str(2) - 15 ' ASCII code for "a"
str(4) = str(2) + 3 ' ASCII code for "s"
str(5) = str(4) ' ASCII code for "s"
str(6) = 49 ' ASCII code for "1"
str(7) = str(6) + 1 ' ASCII code for "2"
str(8) = str(7) + 1 ' ASCII code for "3"

Hi guys,
I'm doing a program that able to login to the website without going to the website using HTTPPost. I face this problem when I need to login into PHP sites, Java Script sites are ok.
I use http://www.somesite.com/members/member-menu.php?username=UN&password=PWD but it seems it can't read the username and password that I pass over, I'd tried with another PHP site,also the same.
This is what I did in my VB.NET code
Dim PostData As String = _
"?" & usernameText & "=" & UN & _
"&" & passwordText & "= " & PWD
Data = encoding.GetBytes(PostData)
So the PostData is suppose to be send to the site to get the cookie but it return a result saying my username and password invalid, I'd tried the username and password on the site which work well. I try hashing them then only send them but with the same result, invalid username and password.
Would appreciate if anyone would give me some idea about this

In my options page has 2 button, 'Save' and 'Cancel'.
After i doing changes for all particular fields in options page, then i click 'Save' button to save it. It works successfully.
But my problem is if user click button 'Cancel', then my program should rollback all transaction and the data will back to previous data before i click the 'Save' button.
So, has any coding to do rollback transaction in VB6??
Angela

That all depends on what you mean by "transaction".
But normally, you'd let the user pick a bunch of options in the dialog and not apply any of those changes until the user clicks Save or OK. Until then, you can just not do anything if the user clicks Cancel.

Hello everybody
I'm workin' on a project in which i have to load an image in an image box every period of time so i'm using a timer to do that, this image comes from another PC using the MScomm.
The problem is that if the image didn't comletely and correctly arrive the computer stuck, even if i put "on error resume next" at the top of the timer.
So is there any way i can check if the image is valid before loading it in the image box.
I appreciate your cooperation and thank you very much.

What kind of image are you using (what format). Also, did you write the other application that sits on the other computer and sends the images over MSComm?! If so, I would add a checksum to every transmission and check that first, before displaying the image. This would tell you if something got corrupted on the way..

I would like to run the VB Application having MS Access Database as the back-end. Condition is the application is in .exe format & there is no setup. The VB Application is not to be installed on the Computer but must be run from the CD.
|

|

Unfortunately, if you're going to use an Access database as the back end, you can't do this. Any access to that database requires read and write access to the database file, which you will not get on a CD.

I have one vb.net windows application with one form; this is a small utility program. This Zip the content of the specific folder in a certain interval and copy the content in to some other place & keep the folder empty always. While running the application this sits in System tray as icon. This runs in the server always (24 X 7). This application I want to run as a windows service, because when ever server gets restarted, I have to run this application manually.
I tried to put this in windows service, it's running, but my problem is, I don't know how to launch the system try icon while running the service. I want once the service starts; my utility exe icon should come in system tray. Any body has solution for my problem.

Then you very badly phrased the question in the first place!
Instead of wasting our time - and yours asking stupid questions - find the answer by searching for it on Google or this great site.

I know this is probably a basic question, but here goes. I am building a Windows form based application. I have a form1 that opens up, users enter information, then I would like to e-mail the selected information from some selected textbox's using another form2. Or is it easier to email the data from the textboxs without a form?
A second minor problem is how do you eliminate the Microsoft Outlook message that pops up when activating the Outlook application from within VB.NET?
Thank you,
LWhite
