In Visual Basic, data can be converted in two ways: implicitly, which means the conversion is performed automatically, and explicitly, which means you must perform the conversion.

You have to do a two states button, either using the text itself to identify the current state or by means of an auxiliary variable.

For instance:

(1) If myButton.Text="ON" Then myButton.Text="OFF" Else myButton.Text="ON"

(2) IF bIsON = True Then
       bIsON = False 
       myButton.Text="OFF"
    Else
       bIsON = True 
       myButton.Text="ON"
    End If

where,of course, bIsOn must be a variable of the Form (or a Static one inside the event handler).

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

You don't add the event twice. You haven't given enough detail about the problem to describe an accurate solution. Where is this text comming from? How is it stored? Change the text to what?

Opening .dll's

I have been given a project which was developed by someone who has just left our company and is not contactable.
He developed the project and put it live but didn't save a development copy. The live version doesn't contain the .vb files
and just everything is saved and compiled as .dll.
Does anyone know how I could open the .dll filesd to see the .VB code??

Too bad! Regards to the developer!!!

The only way to get the code now is by decompiling the dll's. Painful and time consuming. Besides the result might not be what you would expect.

So your best bet is to bribe the developer for the code, or better yet redo the app.

The perfect code is always in your head...it just a matter of how hard you bang your head against the wall to get it out!

Add a table to the dataset then in columns tab in this table add the number of columns u want. then in the grid put the datasource = the dataset and dataMember the table u have just created.

If Iam giving thru the suggestion given by you,

Add a table to the dataset then in columns tab in this table add the number of columns u want. then in the grid put the datasource = the dataset and dataMember the table u have just created.

Then I will get all the data into the grid.but I want limited columns data i.e. only one or two columns/fields from the whole table

I suggest u change ur select * statement in ur stored procedure to select column-name. Then u will retreive only the specific column(s) u specified.
I.E. create ur adapter based on a select column-name & not select * then genertae the dataset and put it as data source for the grid.
Hope that works cause i cant think of any other way right now.

Hence you want to know the application path; then use
Application.StartupPath.

You don't set this path, you retrieve it. The equivilent in VB.NET is Application.StartupPath.

Your header is the forum name, and your post looks like it would have made a good header. Do you have a question ?

What do you mean by ApplicationPath ?

It is hard to figure out what you are asking because vb.net is the forum name.

When you create an application in vb.net you define an application name also an application path. If you app path is different than the original path and then you have to define one.

If your aim is to change the application build output path, you can change it from PROJET menu (Just simle go over the (application properties) and then click the (compile) section.

Play a flash video like it were a messenger wink

Hi everybody!
My question is either for VB 6 or .NET
Please it's driving me crazy...
So,since i have to play a flash video inside my application,i have tried the shockwaveflash component..but it still plays the flash animation inside the form..i have to play it like microsoft messenger does with animoticons(or winks whatever they are called in english..):you know,it reproduces them on the entire screen and just the animations,not showing the form..
how can i perform that?i have tried making the form transparent,but of course also the control contained in the form becomes transparent,when actually i want only the form surface to be transparent.
i don't literally know where to begin....
thank you very much in advance,you are my only resource left...
OMG | :OMG:

Are you sure they are flash videos ? I'd doubt it, I'd imagine they are animating directly onto the desktop.

i am not sure,i am awfully sure.
i have personally extracted for backup purposes one of these winks...search on the internet for .mco files.they are stored as resource files in the msgslang dll (see under msn messenger folder),and are basically cab files with some xml files inside and the flash video in swf format.
but apart from that,the fact is that even if they weren't flash videos at all,i had to follow the way of the flash video because it is the only way i can imagine.
even writing a hta application and launching from my application,i have to use a flash file....
please help!
thank you again
