Why are you still using VB6? It is a dead language.

I'm trying to set NumericUpDown control to Flatsyle.
Setting Borderstyle as FixedSingle effects only to the numberbox.
Is there a way to set also the up/down buttons to flatstyle?

Hi , I'm try to run my VB script which was working fine all the while, but suddenly getting the "Run-time error '9' for Subscript out of range" on my script fro the below code line:
SchemaMandatory = SchemaDetailSplit(2)
The script to take the 3 items:
- Fields
- DataType
- Mandatory
can someone help to advise what I'm missing here 
|
|
|
|
|
You are trying to access an array item with an index that is outside the limits of your array. Look at your code and the data. What does SchemaDetailSplit(2) actually return?

I have this app made in vb6 which use ms access database, when install this app the .mdb file and other files gets store in the app folder i.e. c:\program files\my app\ and my software works fine. But when I install the same installation program in other system or computer the .mdb file gets store in C:\Users\xxx\AppData\Local\VirtualStore\ and its read and update the data from there only. And when trying to export the data to ms-excel its does not get exported though it did not give any error message.
I just wonder what could be the problem with this exporting and the storing the mdb file in this location, I have installed this app on windows 7 system.
Would be very grateful if anyone can give help or suggestion on this.
Thank you
Zela

Starting with Windows Vista, folder virtualisation has been intruduced. System folders like the program files folder are protected from being used for user files and access is redirected to the VirtualStore of the current user.
But even with older Windows versions it was not recommended to use the program files folder for user data.
Your problem is that the installation program is run with administrative priviliges and can therefore create files and folders in the program files directory. But accesses from the application itself will be redirected to the VirtualStore folder.
That you did not get any error message when the database can't be found is another sign of bad application design (besides storing user data at the wrong place).
If you have access to the source of the application and the installation program you should update both to use a common data folder. The most common is
Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)
If not, you should ask the developer for an update.
As a last resort, execute the application with administrator priviliges.

Thank you very much Jochen Arndt for your helpful response. I kind of a little bit understand now how things happen as I run the app with administrator privileges it kind of work now such as extracting data report to ms-excel. The coding is done by me making some modification from code downloaded from the internet.
Well let say it does not matter if the software read the data from virtualstore folder but what i want to make is exporting the data to ms excel. when I run the app through vb without compiling extraction of the data to ms excel works fine. But when I compile it as .exe and run the software, extraction of the data to ms excel works fine in some system but on some system it just does not make any output even though it report as is has done. Could you please guide me on how to rectify this error, since this app is to be utilized by a group of people and if they can't export the report in ms excel it would be kind of useless.
Would be grateful if you could please suggest any idea on this.
Thank you.

If it is your application use a common folder for the database as already suggested. Than you will have no problems and do it as recommended. All you have to ensure then is that the installation program creates that folder.

The above error i.e. extracting data to ms excel occurs especially on windows 10, it does not make any extraction at all, but when run the program or the exe file as an admin its work fine, would be grateful if any one help me solve this problem.
Thank you.

The statement he had put up there seems more like a .NET rather than old plain VB6, I need help on VB6 not in .NET
|
|
|
|

The answer has nothing to do with either .NET or VB6, it is about how Windows allows access to different folders.

Hi All,
I create a program that runs on backgound using VB.NET minicap.exe with CMD as process. Inside the code is module and SUB_MAIN with system timers. It works fine except i notice that when my program runs on background as process? The other application on desktop is BLINKING intermittently. the system timer is set to 2sec upto 10seconds. heres my code below.
The main purpose of my program is to capture screenshot of desktop and save to network drive using MINICAP.EXE and CMD and SYSTEM TIMERS.

If you are capturing images of the screen at regular intervals then you must expect some disruption to the screen display.

I understand that loading of mouse cursor is normal every interval but interacting with other windows form or programs is not.

On a slower PC, the "blink" may become more visible; my PC isn't a very fast one, but running on a high resolution - you'd be saving a large blob every so often.
So no, the spyware isn't going to work.

I dont save it as blob. You can check the minicap.exe by donation coader. it saves directly to shared drive. loading of a mouse cursor if fine. but the main problem is the Windows form is intermittently loosing focus and focusing on minimized forms.

VB6 is no longer supported, and no new code should be written in the language. The compiler isn't sold anymore, and there's no OS for sale that still supports it.
There's several problems with your code, SQL-injection just being one of them. You're also storing passwords, which is a security issue.
If you want to learn to code then upgrade to VB.NET; if this is part of a course or schoolwork, then I suggest you demand your money back.
