ok splash screens are easy
on the form that serves as the splash screen, put a timer control, then turn enabled to true in the properties, and the interval to whatever you want. 1000=1sec.double click on the timer control and enter me.close
Me tells the program that it is only dealing with that one form and close closes the form. If you use End it will close the whole program.

In VB.NET if u close first screen even with ME.Close() it closes all other forms. I.e if i open main from from splash screen then it will close that form also....
|
|
|
|
|
set it up with the timer on the splash screen, then create a module with something like this
Module Startup<br />
<br />
Public Sub Main()<br />
Dim frmSplash As New frmSplash<br />
Dim frmMain As New frmMain<br />
<br />
frmSplash.ShowDialog()<br />
frmMain.ShowDialog()<br />
<br />
End Sub<br />
End Module
make sure that in the timers tick event you put me.close, oh and change the startup object to SubMain and everthing should be fine.

Search the articles for "Splash Screen" and you'll find a bunch of examples of how to do it the "right way".

I just wrote a program and was wondering how to change the appearance of the exe file in the start menu such as adding an Icon.

Hye
Right click on the project and go to properties. In the build option you can change the icon. As far the links in Start menu are concerned. Add a deployment project. and create a short cut in User Program menu for your output exe. and in the short cut properties you can change the icon.
cheers....

insead of writing the long codes you can just work on insert statement. if you could post the value of strsqlinsert variable then we could suggest you
some thing better and proper
|
|

|

well rizwan,
here's the value of strsqlinsert
strinsert = "INSERT INTO Transmittal(ReferencedTo, Title, NumberofCopies, Username, ProjectName, KindAttn, RevisionNumber, Action, DrawingDocumentNumber)" + "VALUES ('" + TextBox3.Text + "', '" + TextBox5.Text + "', '" + TextBox9.Text + "', '" + TextBox1.Text + "', '" + TextBox2.Text + "', '" + TextBox4.Text + "', '" + TextBox10.Text + "', '" + TextBox11.Text + "', '" + TextBox7.Text + "' )"
it doesn't come in one line here.
help me if you could.

Two problems...
The first is that you don't have a spcae just before the word "VALUES", so your SQL looks likes this:
...Action, DrawingDocumentNumber)VALUES ('...
which I believe is a syntax error in SQL...
Second, drop this string concatenation garbage and make your life much easier and convert this to parameterized queries. You'll automatically eliminate about 75% of the problems you get, like the one your facing now!, by using string concatenation...

hi dave,
thanx for your sugesstion. but i did not eaxctly get you. could you just modify the string i sent and then give it you me.
|
|
|
|
|
strinsert = "INSERT INTO Transmittal(ReferencedTo, Title, NumberofCopies, Username, ProjectName, KindAttn, RevisionNumber, Action, DrawingDocumentNumber)" + " VALUES ('" + TextBox3.Text + "', '" + TextBox5.Text + "', '" + TextBox9.Text + "', '" + TextBox1.Text + "', '" + TextBox2.Text + "', '" + TextBox4.Text + "', '" + TextBox10.Text + "', '" + TextBox11.Text + "', '" + TextBox7.Text + "' )"
All you had to do is add a space before your "VALUES" keyword.
This is one reason why you DO NOT USE string concatenation to build your SQL statements. How you're building your statement can be broken so easily, it's silly. All the user has to do is put a ' character in any one of those text boxes and your code breaks. Learn how to do it the correct way now, before this bad habit becomes your normal method.

thanx dave,
the problem is solved by ur code. but the this method is working fine on one application. but on another it again gives the same syntax error. what to do? also what do you mean by parametrised query. or what is the better method can you tell me.
|
|
|
|
|
The syntax error is coming up because you miss-paired double quote marks somewhere.
You can get a taste of parameterized queries here[^].

but dave if that is the case then it should give error in both the cases. in one form the syntax is working fine and in another form it's giving error. i have also double checked everything.
|
|
|
|
|
All I can say is you're doing something wrong. If you're using the EXACT same statement in both forms, you've missed a character somewhere. Think about it! If the statement works on one form, it must work. So what's different about it on the second form?

ii checked everything dave twice and thrice. but the webform on which the code doesn't work and gives the error. also doesn't work with a code as simple as this.
strsqlinsert = "INSERT INTO Chec (first)" + " VALUES (" + TextBox1.Text + ")"
if there is something wrong with it i don't know about it.
|
|
|
|

If your getting a "syntax error", you might want to consider what the field "first" is defined as and what is in the textbox.Text. If your trying to put a string into a number field, obviously, it's not going to work.
Seriously, pick up a book on SQL and VB.NET and save yourself the aggravation.

A quick overview of my project aim might help you understand what I am trying to achieve. I am trying to create an area on a form where users can draw a turing machine! For those who dont know what one is , it does not matter too much (although i believe every computer scientist should at least have a basic background of one as it is the foundations of computing! it basically defines what can and cannot be computed).
Basically, i need an area where users can draw circles(which represent the states of the machines) and lines connecting these circles (which represent the transitions). I would like an place where users can click on a icon in the toolbar and then be able to click on the space to create the relevant shape.
I would appreciate any comments on where i can start looking. I've been looking around, and gdi's seem to turn up, but i'm not sure if this is the best way to approach this. Another semi-solution i have thought of is just to create images of these shapes and create a new instance?? of them as required! I am totally lost...
Thanks for your time and effort!
million thanks,
zoe xx:

If you're using predefined shapes, then you should certainly use an OO structure to define them. If you're using tools to draw freely, the same applies.
Basically, the way I'd do this is to have a base tool class, and have your application always use an instance of it ( the currently selected tool ). Make a collection of drawing events, generated by these tools, and iterate through it to draw your image. This makes undo/redo really easy to impliment as well.

I have seen an article in this site posted by "rainman_63". He has explained UPC-A barcode generation in C# very well. I am a beginner in VB and I need somebody who can convert that c# code into VB6. Your help is greately appreciated.

what don't you understand ?
C# is very easy to translate into VB.NET and vice versa as they are both .NET languages (more difficult with C++ in MFC for example)
