Hi, my first post in this forum, hope this is the right place to do it.
In an excel macro of mine, my application is _really_ slow after i have run my macro. I suppose it is due to the undo-stack that must be really full, because a save,close file,open file get it all quick again. Is it possible to disable the recording of operation done by a macro in the undo-stack ?
Thanks,

Hello,
I've been developed GUI program in VB6.0, now, i'm using VB.net 2003 and 2005 both.
The problem is that it's very slow to show the form controls when I call other form which has many controls in VB.net to compare to VB 6.0. Even though I use BringtoFront property to show form, it's same.
Is that the .net normal symptom ? if not, Is there any configuration to show all controls immediately like VB 6.0 without slow ?
Please explain the basic concept to show the form and load form in .net ?

Create overloads for the AddRecord and Update methods that takes a transaction object along with the SQL query. Use the transaction object in the actual database calls in the methods.

Hello
I want to read a particular bit value from a byte. can anyone suggest me how to achieve this.
Following is the code which gets byte value.
===============================
Structure typByteArray
Public B() As Byte
EndStructure
Dim tB As typByteArray
ReDim tB.B(2)
'say for example it gets the following values.
tB.B(2) = 51
tB.B(1) = 121
================================
From this byte I want to get a particular bit value.
How can I get this. Is it possible.
Reply needed as soon as possible.
Thanks

Hi,
Maybe this will help
I make a function by which you can take arr of bit value from given byte
take a look and tell me if any error of problem occured.
=======================================================
Public Function GetBit(ByVal b As Byte) As Byte()
Dim arr(7) As Byte
Dim i As Int16 = 0
For i = 0 To 7
arr(7 - i) = (b Mod 2)
b = Math.Floor(b / 2)
Next
GetBit = arr
End Function
========================================================
Now for finding the bit value u just call this function and all the bit value u can find.
Like this :
======================================================
Dim arr(7) As Byte
arr = GetBit(22)
======================================================

You can simply use the bitwise And operator, by passing in a byte with only the bit you want turned on. This will return 0 if the bit is not in both, or the value represented by the bit in that position if it is in both. Since you know it will always be in the byte you pass in, there are no problems. This will save you the trouble of converting all of the bits multiple times in a function.
Example:
Dim theByte As Byte
Dim theBit As Boolean
theByte = 121
theBit = theByte And &H8
MsgBox "Bit 5 (from the left) of " & cstr(theByte) & " is: " & cstr(theBit)
The values that you can pass in as a replacement to &H8 for finding certain bits are:
Note: This table is from the leftmost bit (the bit with the most significance)
Bit 1: &H80
Bit 2: &H40
Bit 3: &H20
Bit 4: &H10
Bit 5: &H8
Bit 6: &H4
Bit 7: &H2
Bit 8: &H1

Hello senthryl
I think this one worked. thanks
But now the problem is that I to have to write or change one bit value of the byte.

In VB6, I have made a report using Crystal Report 8.0 through database file (not through ODBC). In this Report, I have added a sub-report but when I view this report through VB then its gives this error,
Run-time Error: 20535
Unable to connect: incorrect session parameters.
This error doesn’t happens when I remove the sub-report. I have checked all the linking of report to sub-report but it doesn’t work. This doesn’t happens when I use ODBC as datasource.
Can Somebody help me
I use this code on the Print-Button
With MDIForm1.CrystalReport1
.Connect = database.MDB;PWD=password"
.ReportFileName = the required file name
.SelectionFormula = ""
.WindowShowPrintSetupBtn = True
.WindowState = crptMaximized

How to search in listbox...
I have listbox and text box, and now when i type in textbox exsample 0435 that it shows and select the item in listbox that starts with that number
|
|
|
|
|
|
Not helping...
Maybe you didnt understand.
Exsample:
Listbox contains items like:
054 - Tree
056 - Box
087 - Coke
089 - Keyboard
e.t.c.
And now i have two radio butons... One is Searching by Id and other is Searching By name.
If i select radio id button i want that it searches in listbox just the number before text in item. So if i type 056 in textbox that it selects the item that starts with that number.
Or if i select the tex radio button i want that it searches for text typed in textbox. So if i type Coke in textbox that it selects item that contain that text.
Understand now? Please help me solve that problem.
Thx.

The link I gave you is to the same InnoSetup that I've used successfully in the past. It definately does accept exe files.
An alternative would be to write your own installer, failing that try this[^] and you'll find this[^].
