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. I can obviously drag and drop 100 buttons onto the form but this lacks a certain style, it would also be a pain. How do I create a form covered with required array of buttons automatically?
View 3 RepliesSo as the message says i believe im having a problem when declaring an array as control. The background:Im doing a school project where a picture is covered by 48 buttons. When a user clicks a button, they are asked a question. If they answer write, the button disappears until the whole image is displayed.
Im using each buttons visible property to hide it. Now that i think about it, i should probably un-enable it after a question is answered correctly.anyway, I keep getting a NullReferenceException when making the visible set to false. Any suggestions would be awesome. I have already created all the buttons and named them Q1-Q48.

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}
private sub GetCaption (ByVal x as integer)
myBtn(x).text="OK" 'If x=2 I should execute button3.text="OK"
[code]....
call GetCaption(2) 'Call the sub and change the text on button2 to say OK.How do I make it work?
I have a toolstrip on a winforms application and below it a DataGridView. Everything looks fine when the program runs initially. If I maximize the form though, the DataGridView covers part of the toolstrip. How can I make the toolstrip lock in place so that nothing will overlap it?

View 6 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?

View 1 RepliesI am using a datapager inside a nested Listview succesfully. When only one record of data is available the next previous last and first buttons are faded as per normal. However I would like them to not appear at all.
The aspx code I have is:
<asp:ListView ID="Pictures" runat="server" DataSourceID="SqlDataSource2" >
<EmptyDataTemplate>
<span>No data was returned.</span>
[code]....
However the pager is always nothing in the debugger i.e it can't find the control.This may be because I have not selected the event handler correctly (I've tried several) or the method may be wrong.
i am trying to create a program which is a polling booth.Create a VB.Net program to implement the polling booth system.The program should contain 1 button and 1 textbox for each candidate.Two radio buttons are required to record gender.A vote cast button should also be available to initiate the recording of preferences updating the array values.If the vote cast is successful, a message should be displayed and the text boxes cleared, otherwise a message to the constituent will explain they need to adjust their preferences e.g. if two or more candidates receive the same preference. [code] All preferences entered into the textboxes should be converted into a numerical value and used to update a vote cast array i.e. an array that can hold decimal values (single data type) with 7 elements. The first 5 elements in the array will correspond to each candidate while the last 2 elements will record female and male totals.Each preference textbox must only allow a single character length; validation of the entry must ensure the value is either numeric (between 1 and 5) or left blank.The program cannot be closed down unless a code is entered into the voting boxes.
View 1 RepliesI'm using Visual Studio 2005, net framework 2.0, Microsoft Internet Explorer ver 7.0.5730.13. Create a form with the webbrowser control and two buttons. Use the code that i provided at the end of this question to understand the scenario. As far as i know, this behaviour happens only on the myspace.com web site. 1. Navigate to your myspace.com inbox page, read a message and click on the reply button to reply to the message. The page will show correctly in the web browser.2. Then click on Button1, repeat the same process (read a message in the myspace.com inbox, click on the reply button), and the textboxes where you have to enter your reply will be gone.3. Then click on Button2, repeat the same process, and the page will show correctly in the web browser.4. Then comment out or remove the oDoc_MouseDown event, click on Button1, repeat the same process, and the page will show correctly.Why does the page shows correctly when the oDoc_MouseDown event is removed? The same behaviour happens if you use any other event of the oDoc variable.I desperately need the page on myspace to be shown correctly with the oDoc_MouseDown event and other events of the oDoc variable.

I created several Reports in Visual studio. and now I would like to create a form with buttons that open the reports. I have been searching for the code to open a report but cannot find anything useful.
Do I have to add al the Report projects to my ReportForm project or...?
I need to create a form with radio buttons, text boxes, labels, etc.. This information needs to be pulled from a database. For instance, I have a form that displays information that needs to be inputed to a database, based on what test is being done for a specific product. Each product requires different tests. So each product may or may not have the same information that needs to be inputed..
What I have done is made a database and filled a table with each product and what tests apply. I then call that database after the product has been selected for the tests. It will then fill an array for that products information for what texts boxes and labels need to be shown. I wanna take this further and have it create a form through code and align all the controls to specific spots so that it will look nice. For example I wouldn't wanna create a control and have it be cut out of the form, or have other controls overlapping others.
[Code]...
Using VB I can create and access a random "cell" in an array like so
[Code]....
I have a button (named Test) and I have the X and Y coordinates of the 3 buttons (Which are A, B and C) to click. Now what I want to do is, when the Test(button) is pressed, timer1 (22 seconds) would start and after 22 seconds it presses automatically button A and if it isn't the right button then it will wait another 22 seconds and then presses button B and if it is right it will start another 22 seconds and if it is wrong it would start another 22 seconds and press button C. If the correct button was B then another 22 seconds would start and this time it would start again from A.
1.When Button TEST is press the timer will count down 22 seconds.
2.After 22 seconds it will press the button A (timer will stop)
3.If button A was the correct letter then Timer will count another 22seconds.
4.If button A was wrong it will start the timer (22seconds) and then press B (timer stopped).
5.If button B was correct, timer will start another 22 seconds (back to step 2)
6.If button B was wrong then timer will start and will click button C. (timer stopped)
7.If button C was correct then timer will start (Back to step 2)
8.Will continue like this until 25 clicks had been made then it will stop.
I have 7 Windows forms.The order of the forms is defined within a configuration file.I want to place buttons on each form that will show the next available options.The Next button will move the next form in the list.The Back button will move to the previous form in the list. The Finish button will execute the final piece of code.The Cancel button will exit the application.If the user is on the first form, then there is no Back button.If the user is on the last form, then there is no Next button, but there is a Finish button.
Example 1:
Form1 - Next, Cancel
Form3 - Next, Back, Cancel[code]....

I'm trying to create a program that installs required .dll's for a program due to a clean install.What I need to do is Get a value in the registry and use it for the program files path.. but I've noticed some pc's don't have the same configuration because of the version the user is using. Anyway This is what I have so far:

What I'm trying to do is find a registry key called "SoftInstallPath", if found I need the end of the path to goto the new directory(new_dll) not the old one (dll).. and if "SoftInstallPath" cannot be found.. I need it to find "ProgInstallPath" and use it instead and do the same thing.
I need to read a named range into an array. Then if the value in the 1st position matches a static value, read the value in the second position. I've been looking into array's and this is what I think will work, however I get a compile error on the columns.count "constant expression required". Is it because in the DIM statement I'm attempting 2 things? This is a macro in Excel. The range name is Data1 and the string comparison is "AnyString". The second value will be an integer.
Sub macro1()
Dim rng As Range
Dim x As Integer
Dim y As Integer

I have 81 text boxes on a form and would like to create a text array in code that will equate to these boxes on the form. Once I've assigned each text box from the form to the array entry, I'd just like to work with the array - then have the actual text boxes on the form reflect the changes made to the array.

In my project, I have a form with a background pic that I like, but unfortunately, I also have a ListView on that form which covers most of the picture. Now, is there a way to find the part of the background image concealed by the ListView, and then display it as a background image of the ListView at decreased opacity? You know, like a vague image.Just one more thing, setting the form's transparency key to the background color of the ListView is not an option.

View 2 RepliesI've written a program using Visual Studio 2008 Standard Edition in Visual Basic. It's a Windows Forms Application. The program is very simple, it just reads a directory of text files, parses the text and outputs another text file as .CSV file
for import into Excel. There's no user interaction required but it never displays the form and therefore the progress bar. If I put a GO button on the form and modify the program so that the subroutine that does the processing isn't called until the user clicks GO it shows the form and the progress bar etc. How can I make the program run at startup, show the form, show the progress bar and then pause for 10 seconds or so and then exit?
