There are differences between VB6 and VB.NET. VB6 has been dead, and unsupported by Microsoft since about March 2005. VB.NET is more closer to be really object oriented than VB6.

VB6 is a muddled mess of a language which is saddled with oodles of quirks which were designed to make it somewhat compatible with QuickBasic and QBASIC, which were in turn designed to be compatible with the original IBM PC Cassette BASIC. Although it "looks" object-oriented, it lacks features like inheritance which are necessary to make real object-oriented programming possible. Further, as a result of its Cassette BASIC roots, many object methods have strange and bizarre variations in syntax which cannot be mimicked with user-defined functions. For example, to draw a box on the printer,

Printer.Line(10,10)-(20,20),0,BF

The use of two coordinate pairs, separated by a dash, and the use of the literal characters "BF" (block fill) without any string delimiter, are both perfectly fine syntax in an interpreted language (like Cassette Basic). They're not really any harder to parse than would be "LINE 10,10,20,20,0,2" (the "3" being "BF") and they're easier to read, but syntax line that makes it impossible to create a function that behaves like the "Line" function.

Take a look at this book. I have it and found it to be a pretty good resource for making the transition, if you haven't already.

The only similarities are that they both have "Visual Basic" in the title and the message box function is MsgBox() in both. Smile | :)

Actually, the message box method in .NET is MessageBox.Show. The MsgBox method in VB.NET is just a wrapper for the MessageBox.Show method.

Also, it's far from the only VB 6 leftover. VB.NET has a lot of wrappers with the same name as the VB 6 functions, that call the corresponding .NET method.

Despite everything, the person most likely to be fooling you next is yourself.

hi jds1207

When i heard there was vb.net, i was in vb6, and i thought, no am happy here at vb6, and i was so Stuborn and never wanted to Listen when they told me about vb.net, One day i had a problem in my code and i post a thread in a forum and i wrote something like " i have problem inserting records in vb", well the person who answered me, thought i was using vb.net and he posted an example code of vb.net, am telling you it was Completely different and made sense than my vb6 code. Initialy i thought i was going to learn there and there and grasp the language, but i was lying to myself, i had to start learning the Language from Scratch , and till today i dont see vb6 come Closer to vb.net. The Syntex might look alike but they are Completely Different.

DataGridViewCellStyle Format

2-Jul-08 2:49

In my DataGridView I have a column displaying date and two columns displaying time (begin/end).
For the date column I set CellStyle format=d, so users can only enter proper dates and it works fine, but I don't seem to get it working for the time-columns. Time should be formatted HH:mm, but when setting format=t users still are able to enter into the time-columns whatever they want.
Solution anybody?

-edit-
Thanks, found the error. The column in my datatable, which was bound to datagridview, had the datatype string instead of datetime.

Hi

I added a control named Shockwave flash object from com object to my toolbox but when i drag it to my form it gives error that:

Failed to import ActiveX control, Please ensure that it is properly registred.

Can any one give me the right way to do it

Thanks

Find another activeX control that is better than what you are currently using. Their may be a compatability issue with using it in Visual Studio. Or if you can use WPF, convert the flash object to XAML.

If the designer for visual studio crashes or does not allow the activeX control to be added to a form, then their is a problem. The problem is most likely because of an incompatability between the activeX control and either visual studio or the .NET framework. To fix the problem, ditch the control and find a replacement. You can either find an activeX control that works or you can use the Windows Presentation Foundation (of .NET 3.0). To use WPF you would have to convert the flash file to XAML.

First thing I spot is that you are using the wrong port number. I have code similar to yours for my own application (I can't get to it at the moment, otherwise I would post it), but you can start off getting the correct port number.

DataGridView Column ordering

Hi Guys

I have a .Net WinForm with a bound DataGridView which has been formatted in design view. All columns are bound to the datasource in design view with datapropertyname and Grid datasource is passed at runtime. Some colms are visible, frozen and invisible. Issue I have is I cannot seem to order the columns properly. What it shows at design time is not what is displayed at run time. Everytime I order the columns at design time, it just reorders as it likes. I tried to control this at the Designer class and still was no luck.

Can someone help me please.

Before you bind the grid to the desired datasource, make sure you set the grids AutoGenerateColumns property to False. I expect that will solve your problem.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
