So i've uploaded all my project folder and my access database for you to rewiev it.Also excuse me for my englsih. It's not my native language. And again i'm new on VB, so i can ask dumm questions about basic. I can use some qualty VB 2008 tutorials links too.
I understand that currently vb.net message boxes support buttons like ok,cancel,yes,no,abort,retry.but i am wondering how do i customize my own message boxes such that i can rename the yes,no buttons to any text like delete or discard.

View 2 RepliesI know you can make an array of button. But the buttons are already put on the web form in specific spots. I have the buttons named like- button1, button2, button3, button4, button5... Is there a way to use that in an array even though the buttons are designed from the start and not tied to an array from the start? I basically do not want to make a routine for each button and would like to use just 1 routine and add to the counter to update my access database[code]...

Using VB2010, I would like to create an array of buttons and a sub procedure that when I send the index number, I will be able to change the text on the specific button.
Dim myBtn as button={button1, button2, button3}

myBtn(x).text="OK" 'If x=2 I should execute button3.text="OK"

View 2 RepliesI have some experience with VB6 and it was easy to do a control array for radio buttons such that btnSMP(0) and btnSMP(1) and btnSMP(2) were together and if user clicked on btnSMP(1) it was shown with the blck dot on it as selected. If one then changed mind (which seems to be a very common thing) then if user clicked on btnSMP(0) then it was selected and the other one was not.That is not possible in Visual Studio 2008 for what ever reason the higher ups decided. I have read a number of articles now in MSDN about how to duplicate that feature in VB.net code but it seems to be a lot of work and they add in many features I do not have a need of

Attaching code to buttons when they're clicked is easy when they're static buttons on the form; just double click the button on the form designer and add code to the event.
I have a series of buttons that are generated in a control array, so they're generated in a class, and in the form there are no buttons until runtime.
So newbie question with a probably simple answer...how do I enter code for the click event for buttons that aren't there until they're instantiated as a class at runtime?
In VB6 I could set up code to loop through say 10 option buttons to check their values. The code would be something likie this:[code]But in VB .NET it seems that if I use the Controls command as above I cannot use/check the Checked property as Control does not take that as a property of Control. It seems also that I may have to use the Find property of Control as in "Controls.Find" etc.How can I do this in VB .NET? I have a very control intensive application and I must be able to easily loop through controls and check their values without writing out 10 x the code required.
View 8 RepliesI have a piece of software with two tabs, inside each tab there are buttons (the user can add the buttons when they want). when tab1 is full tab2 should start to fill. I currently know how many buttons fit on the screen so I just say something like if buttons > 150 then start to populate tab 2 The problem i have now though is if the resolution is changed then a different amount of buttons can be displayed. so if I put my screen to 1280x720 some buttons are left of. I was thinking of detecting the resolution and then using different cases for different resolutions but this seems very inefficient im wondering if there is a different way?
View 5 RepliesWhen I used to play wiith VB 5.0 I was able to create an array of comand buttons on the form. This allowed me to have one routine that knew which of many buttonshad been clicked and I could then take specific action based on which button was clicked. I can't see how to do this in VBE 8. Is this possible?

I am trying to build a battleship game. The project is giving me one minor difficulty (so far). I do not know how to create the game board made up of 100 buttons.

View 1 RepliesI am fairly new to VisualBasic .NET (2008). I'm creating an application that, when a number is entered into the textbox, a new form window is created and populated with buttons. Each button starts the same command, but with a different parameter (the parameter being the pertinent record number found by the search).'The records are asset tag numbers.The procedure works fine if there is only one result.But the search allows for partial numbers and that's where the trouble begins.If two or more results are found, each button is configured with the last number found. The button being clicked doesn't tally with the proper ID number.[code]
What I didn't count on was that the event is only called when a button is clicked. When buttons are made, they are not assigned at that time.I've had problems trying to carry over the (current value) for pcArray(i), hence having it populate that form3_text field. When trying to add in a second object to be passed, I get the following error:"Method prtivate sub DynamicClick(sender as object, pcNameInfo as object, e as system.eventargs) does not have a signature compatible with delegate sub event handler with delegate 'delegate sub eventhandler(sender as object e as system.eventargs)."I tried manually entering a "Delegate sub eventhander" with the pcNameInfo object and VB 2008 ignores it.What can I do to get each newly made button to be told to run the RemoteIn(pcArray(i)) process properly?
