Hello
Recently I converted a VB 6 program which contained public record structures using the VB 2010 upgrade option.
There were surprisingly few syntax errors which were easily resolved. The program does however use public record
structures for storing data in external random access files...
I am converting a batch of VB6 programs into VB.Net
Most contain many instances of Ariel / MS Sans Serif font size 8 (labels, text boxes etc) and I was wondering
if there was a rapid way of changing these to font size 10 without going through them individually ?
Good Morning, I was wondering if anyone could point me in the direction of finding code that would shade in the overlap areas between circles and also the areas under and between graphs ?
I am using the following code to examine the color of each point on a picture box and then changing it before
redisplaying as a different color on a 2nd picturebox. Although it works I was wondering if other colors outside the
RGB range could be utilised ? Also I have been unable to find any...
Owing to VB6 not having the standard Hyperbolic Trig functions (Sinh, Cosh etc) I have written routines to calculate them from scratch,
e.g Sinh(x) = (e^x - e^-x)/2 and Cosh(x) = (e^x + e^-x)/2
However when multiple calculations are required within a loop then the process grinds to a halt as it...
I have a program which uses the Arcsin and Arccos features of the language.
I have found that if the value to be converted into an angle is 1 or greater then the calculated value
returns as "Nan".
If the value is less than 1 then the angle calculates correctly.
Is this a known problem and are...
I am trying to convert 2 programs from VB6 into VB 2010. Both use Direct Draw graphics features
and generate dozens of conversion errors. Basically each time Direct Draw is referenced.
Have you any ideas on how to handle these?
I have a program, developed in VB6 on Windows XP, which extensively uses the Compute.Eval method to perform calculations
based on inputted text (e.g x*Sin(X), Log(X) etc). However when moved on to a Windows 7 environment the program no longer works,
except when the compute statement is removed...
Around 8 years ago I downloaded a VB 2010.Net program from Microsoft which has source code for creating and manipulating an
on screen Abacus.
The program works when it is run directly from the source code. However when an executable is created this crashes out with
an undecipherable error...
I have a legacy VB6 graphics program which achieves realistic scrolling using the CopyMemory feature.
When I move the program from Windows XP to W7 (or higher) the program crashes on attempting to run.
Removing CopyMemory solves that problem but much functionality is lost.
Are there any...
I have a dozen or so programs written as Windows applications in VB.Net and would like to convert them to Web applications.
Is this a straight forward task or are there many difficulties?
I have downloaded a VB6 program from a source code website. The program uses hundreds of horizontal
and vertical lines which can be moved around and made visible or invisible as desired.
Unfortunately the original programmer displayed everything on the Form and I have tried to introduce
a...
Sometimes when I open an (old) VB6 Project and make changes to a form (e.g form1.frm)
instead of saving the changes to form1 the system insists on renaming the form
usually to something like 1.frm or &.frm.
Is this a sign that the Project has become corrupted and can anything be done to remedy...
Using VB.Net 2005 I have set up 30 text boxes enclosed within a Group control.
I then try to populate them using a For each (item) in Group statement.
The text boxes do get populated but in REVERSE order. Why is this ?
Good evening. I have several VB6 programs which use the Direct Draw control method for displaying graphics.
When I try to convert these into Visual Basic 2008 programs I encounter dozens of errors which can only
be removed by commenting out any line which refers to Direct Draw. I realise one...
I have some old VB6 programs, originally written for XP environment which use statements
such as CopyMemory and features of Glut32.DLL. However when migrated to Windows 7 or higher
