DialogResult - Difficulty Using The Response To A Message Box Question
Apr 15, 2009
I am working on an application and have encountered difficulty using the response to a message box question. I am trying to call one form if the user clicks yes another form if the user clicks no, please have a look at my code and see if you can see where i am going wrong because no matter whether i press yes or no the frmTransactionMenu is being shown and never the frmExit
Dim response As DialogResult
MessageBox.Show("Would you like to complete another transaction", "ANOTHER TRANSACTION ?", MessageBoxButtons.YesNo, MessageBoxIcon.Question)
[CODE]...

So, what I have is a windows form with multiple user selections. I need to display one message box upon click which concatenates strings based on the users input. The message box needs to show each specific reason why the user is declined. I'm typing out some really basic pseudocode below to give the basic structure of what I'm trying to do. [code]

ok here is my problem, im making a little app for school since our school blocks pretty much everything so here is my plan a student makes 2 gmail accounts one for school one at home.
in the program at school (client) they put a site request into a textbox and they hit send, the request is then sent to the home pc gmail account and another app on the other side downloads the full site that they have requested and then sends them an email back with an attachment of the complete website, it is then opened in a browser and they have the site, simple idea and it would be easy except.
my school blocks the smtp protocols in vb, even outlook cant use gmail accounts only the schools registered email, however, you can access gmail on the internet without any blockages and you can send and recieve on the gmail website.so how can i use a webbrowser control to log the user into there gmail account through a custom gui, and send a string like www.facebook.com to the home pc gmail account, and then use the web browser controll on the students laptop to recieve the response email through a web browser, is there some kind of gmail api i can use?

I have a VB.NET form (CopyScenarioForm) with a OK button (DialogResult property = OK) and also assigned it as 'Accept Button" for the Form.
I show this form from my main Form (mainForm) using
If DialogResult.OK = CopyScenarioForm.ShowDialog() Then
DoSomething()
End if
Now when user clicks on the CopyScenarioForm.OK button, I want to validate his entries and if invalid I want to 'Exit Sub' from the OK button's click handler but when I do that the form still closes out and DoSomething() gets executed. Is there a way to stop this and keep the form alive and only exit if the inputs are valid. I noticed, if I change the OK button's DialogResult property to 'NONE' instead of 'OK' then it doesn't cause it to close. but then how Do I know how the user exited the form to execute DoSomething().

I have a code to print in VB.net. I don't have any problem with the printing as it works, but there is a part which is underlined by green, a warning on "DialogResult = OK". Why the DialogResult = OK is underlined by green colour? The printing work only this underline is making me puzzled

I have the following code [code] This loop takes sometimes up to a minute to execute. I would like to display a message box giving the user the option of terminating the loop. When I use ShowDialog the loop doesn't execute until DialogResult is returned. When I use Show, the forms buttons are not accessible until do loop is finished. How can I make this work?

I'm using Visual Studio 2010 and Excel 2007. I'm having difficulty figuring out how to convert an office excel project into a vb.net project. I wanted to take the ugly windows 98 style buttons I currently have in my spreadsheet and replace them with controls on a new tab on the ribbon. I can make it that far, but I didn't anticipate the large gap between languages.
The code below is supposed to take a bunch of information from a windows form and insert it into a new row on sheet12, sort the table of info, and name the range. Right now visual studio show no errors until I actually try to run the code at which point it says "Object reference not set to an instance of an object." regarding the code "oSheet.Rows("1:1").Copy()" I don't think I understand declaring my variables in vb.net.

In my tic tac toe game I'd like there to be three different levels; easy, medium, and impossible. There are 2 forms; the difficulty level form and the main game form. When the game first starts the user will be prompted with the difficulty level form which contains 3 radio buttons; easy, medium, and impossible.
I've coded three different functions based on the difficulty level; easyMove(), medMove(), and impMove(). These have all been coded in the main game form. How could I run the respective function based on the radio button that was selected in the previous difficulty level form?
If it was on the same form it wouldn't be a problem but because it is on a different form I'm unsure of how to do this.

Okay, i've tried httpwebrequest, webclient, and a couple of others methods; using the headers parameter of each to set headers and then either opening a response stream or simply setting the system.net.webclient method to download a response into a string. Put simply, how do I make a simple GET request with a few headers and read the data back! I am very, very stuck in a hole right now..

I am currently developing in Visual Studio 2008 (Visual Basic) and I have no problem reading, editing, saving, etc. to a 2007 Access database that is stored locally using the following code:
Dim NotifyDS As New DataSet()
Dim NotifyCon As New OleDb.OleDbConnection
NotifyCon.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|DataSettings.accdb"
NotifyCon.Open()
Ultimately I am going to be installing this program in my office on multiple computers, but would only like to have one "server" program where the database is installed. All of the other computers will have access to this one database over the LAN. For some reason I am unable to access this remote database file over my LAN. I have tried all sorts of things (including a username and password for the server computer),

I'm not sure if this is really a VB IDE issue, or a more general VS10 issue, but I couldn't find any other relevant category to post in, so here goes!I have several VB projects which I want to use in the same solution in Visual Studio 10. I created a project (& corresponding solution) which will reference them and added the existing projects by right clicking the solution in solution explorer choosing 'Add->Existing Project'. Then I went to the containing project's Properties window and added references to the existing projects, so they could be used by the project.

I'm having a strange difficulty. Here is the order of events:User presses button on form1 New Form object is created for from 2 New form object '.show' command is fired Form 2 opens correctly In the Load Event of Form 2, the form attempts to do various things in a try, catch, finally clause On catch, I close form2 down '.close' as it cannot be used as something has gone wrong with the execution However, my problem is this. It is acceptable for things to go wrong on the from 2 load event which is why I have implemented the try - catch functionality. However, when I close the form2 down as a result of the problem, a real error ocurrs 'Cannot access a disposed object' and the VB IDE refers me to Form1's '.show' event for Form2.
It is almost as if the form hasn't fully 'shown' before I am closing it down. Does anyone have any idea what the problem is here? Do I need to close down Form2 ourside of it's Load event handler so that Form1 thinks it has loaded correctly?

I'm attempting to import an excel spreadsheet into a dataset. The spreadsheet is selected by the user by browsing for a file. I can get it to work properly only if I know the exact sheet name, but it varies from sheet to sheet. I need to tell it to always use the first sheet in the workbook.
I've declared the following at the beginning of my project:

I am giving the code below so that you can givthe problem is, I have to take 12 DateTimePicker to do that job in a single form which is creating a saving problem means when I click save button it takes long time to save. Now, I thought If I can do it by using TextBoxn a date format would easeup my save problem. Or it can be MaskedTextBox as well. Below is my code if any one can give me the solution.

Recently I started a project with the goal being to have text that was inputted into a textbox stored within a three dimensional jagged array. The idea is that every time a button is pressed, whatever text that is inputted into the textbox is split into separate elements, where each word occupies its own element in the array. So for example, if a poem were entered into the textbox and the button clicked, each word of the poem would be assigned to a discrete element in the vertical dimension, and each line of the poem assigned an element in the horizontal dimension. After the text is stored into the 3D jagged array, the text should be cleared from the textbox and a counter should then ensure that on the next button press, the new text inputted into the textbox is stored in a discrete element of the array. Below is the code I have written so far, but I know that I am far from having anything might accomplish what I have just described.

I have the following Query:
SELECT *
FROM tbl_Muffins
WHERE OvenLoadId IN (
SELECT OvenLoadId
[code]....
The idea of the query is that I want to specify an OrderId, and I want all Oven Loads that have items from that order in them, as well as ALL OTHER ITEMS in those loads, even though they could be from other orders.The query works as expected, but I'm not able to use it for my Crystal Report I've written it for.I have put this query into a User Defined Function, however I'm unable to use a call to that function as a table source in my Crystal Report. I am using Visual Studio 2003 (I know it is old, the client refuses to upgrade).

create a message box that stores my user name, message, and post datetime into the database as messages are sent. Soon came to realise, what if the user changed his name? So I decided to use the user id (icn) to identify the message poster instead. However, my chunk of codes keep giving me the same error. Says that there are no rows in the dataset.

I am using Visual Studio 2005 for coding. I am doing an exercise where I have to create a data lookup program. The program is to illustrate the concepts of using a database to look up information based on user input. The program allows a user to input two search criteria for a product search. The program then displays each individual search result, or record that meets the search criteria in a message box. I am not getting the message box and I don't know why. No errors are present during compiling so I have no indication as to where the problem is.
