Which line gives the error?

Perhaps the problem is:
Text1.Text (String Datatype) = i (Byte Datatype) MisMatch...
Not sure why you convert Integer to string, and then back to string for the Textbox?
This may be of interest (but its vb.Net so not sure about VB6):
Convert a decimal value to binary, octal, or hexadecimal
The ToString method of the Convert class lets you easily and quickly convert a decimal value into a string representation of that number to binary, octal, or hexadecimal base:
' convert to binary<br />
Convert.ToString(11, 2)) ' => 1011<br />
' convert to octal<br />
Convert.ToString(123, 8)) ' => 173<br />
' convert to hexadecimal<br />
Convert.ToString(254, 16)) ' => fe
The ToString method is overloaded to take a Byte, a Short, an Integer, or a Long value in the first argument; the second argument can only be 2, 8, 10, or 16, else an exception will be thrown

+convert byte array to string
StrConv(btArray, vbUnicode)
+convert string to byte array
make the byte array the same size as the string
use copymemory api.
CopyMemory btArray(0), ByVal sText, UBound(btArray)+1

Use NotifyIcon Component, Drag a ContextMenuStrip and use it to assign different actions like to Show your software etc then assign this to the ContextMenuStrip Property of NotifyIcon then on runtime just hide your program and make visible property of your NotifyIcon to 'True'. Explore the properties of NotifyIcon for more functionality !
Hope it helps !

Hey All
I just wanted to get some feed back on my concept?
I quite literally spent days trying to work out why when I exported data to excel I could not no matter what, remove the instance of excel form the task manager…I tried every know method in every possible combination I could find on Google and ideas on these forums but it would not die
I didn’t want to use the known kill all excel instances loop as although an easy fix isn’t very user friendly as if the user has an instance of excel open, that will be close too and they probably wont like that too much…so I managed to come up with this solution which I hope or believe will finally solve the problem but has one perk to make it different
The code boasts that you can export data to excel…dispose of the excel instance in the task manager …BUT THEN … opens the file for the user to view… with the difference being, when the user now closes the file, the instance of excel is removed from the tack manager unlike if when closing an instance of excel created though automation which will stay in the task manager

I'm using crystal report and vb6. I posted a thread two days ago regarding changing the connection properties of the crystal report in vb6. I found a way by using : crxReport.Databases.SetDataSource rsReport
but I'm having an exception report : "The exception unknown software exception (0xe0434f4d) occurred in the application at location 0x77e55e02"
The report shows but after opening several reports the error message occurs.
This is my scenario:
"I'm using a udl for my connection. I have two databases namely TK and TK_MCC. TK is for other company and TK_MCC is for the subsidiary company. I used TK database when I created the crystal report. I used the setdatasource to pass the recordset to change the datasource location of the crystal report. So even if they change the database TK to TK_MCC they can still access the report. But when I did the setdatasource there was an exception report. (The exception unknown software exception (0xe0434f4d) occurred in the application at location 0x77e55e02)"
Before it was working fine when I don't have to change the database.
By the way, i tried it also in another computer (just installed the program) but the error message was different. The other error was error28 out of stack space.
Can someone help me on this...
Thank you very much.

I like to replicate keys typed inside a treeview control through to another window (say another textbox) without setting focus to the textbox first and then using vb's sendkeys function.

Use a delegate to pass values between windows.

Hi there,
I would like to change the hideselection color from the treeview. I have set it to false, and i've noticed that the color is equal to the systemcolor control.
Is it possible to change this color to for example Red?
Thanks

You can't change TreeView.HideSelection Color directly.
But to change HideSelection color here is an another solution
1) TreeView.HideSelection = true
2) Declare:
Public previousSeletedNode As TreeNode 'To hold reference to previously selected TreeNode
3)
Private Sub TreeView1_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles TreeView1.Validating
TreeView1.SelectedNode.BackColor = Color.Yellow
TreeView1.SelectedNode.ForeColor = Color.White
previousSeletedNode = TreeView1.SelectedNode
End Sub
4)
Private Sub TreeView1_AfterSelect(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterSelect
If Not previousSeletedNode Is Nothing Then
previousSeletedNode.BackColor = TreeView1.BackColor
previousSeletedNode.ForeColor = TreeView1.ForeColor
End If
End Sub

Can anyone please let me know how to convert the data type of a field under Crystal Reports I'm using this code in the formula editor but gives me an error 'A Field is Required'.
sum (ToNumber({A String Field}))
I know it takes only Numeric data type fields but is there any way to first convert the string into a Number then calculate its Sum?
Thanks in Advance !

Is it possible in VB to open up a word doc/template replace some certain words with information read in from a csv file and then print this doc/template ? I suppose in effect it is a simple mail merge.
I've written the bit to open the csv file and read the data in but am a bit stumped as to how to open a word doc and replace some words and then print.
Any help gratefully appreciated.
