My project is like this. When I select from "TypeComboBox" and "BeanComboBox", the "PriceTextBox" will display the appropriate amount of the "Private PriceDecimal". But when I added the "Private SnackPrice", it will display only the 1st array, (0, 0) for both array. I try using "Select Case" but doesn't work. I don't know what the problem is. Or maybe it can't be done like this? One structure can have one array?
Private TransactionCoffeeSale(30) As CoffeeSale
Private NumberTransactionsInteger As Integer
Private SnackPrice(,) As Decimal = {{1D, 2D}, {3D, 4D}}
Public Class Form1 Private GIFAnim As Image = Image.FromFile("c:cointosscointoss_ani.gif") Private frames As Integer Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
This is so that the animation has time to play and stop and then the rest of the code will display the other picture and the numbers. Is this possible? I tried timer and sleep but I cant get them to work.
I have to search within an array and display the number of occurrences that a value within the array appears. I know that my code is incorrect but this is what I have so far. If anyone can point out what I am doing wrong that would be great.
Private Sub btnResult_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnResult.Click Dim intSearchAmount As Integer Dim intCounter As Integer Dim intIndex As Integer
I am testing to insert a record to the table from the form by button click event.Data was temporarily hard-coded for testing.There is data grid view opened on the form as well.When the button is clicked, the data was inserted in the data-grid.But after exit out, I don't see in the table.When I run the program, I don't see in the data grid view as well.
Dim newCustomerRow As CustomerLookupDS.CustomerRow newCustomerRow = CustomerLookupDS.Customer.NewCustomerRow() newCustomerRow.CustomerID = 123
I submitted 2 questions but I forgot to assign it to a Forum.... Is there a way that I can find these posts and edit then and attach them to the right forum?
it's about object binding, yes it's just a simple binding. but i don't know why it won't work.for summary, i will write about what i am doing:
1. i have one solution, and have two project in it. WaitressDataWin and WaitressDataObject
2. inside WaitressDataWin, i have 'waitressdata.vb' . this is my simple form , there are some basic textbox (waitress name, address, phone)
3. inside WaitressDataObject, i have 'waitressDataObj.vb' is where i put my object class, i have WaitressName property, WaitressAddress, and Phone.one of my property is like this, others are same except the name of course.
Private _WaitressName As String ''' <summary> ''' Gets or sets the Waitress Name[code]....
4. i create data source , that is object data source. i add reference so i can add my second project which is WaitressDataObject and set the WaitressDataObj as the data source.now i have datasource with three properties (WaitressName, WaitressAddress, Phone)
5. I bind my textbox, by dragging the WaitressName (in datasource) to my waitressname textbox .. so on to all my properties.., i also get bindingsourcecomponent, WaitressDataObjectBindingSource
6. then I put this code to my form load :
dim wdm = new WaitressDataObj Me.WaitressDataObjectBindingSource.DataSource = wdm
7. done, it should've been worked, but it didn't , i don't know why.. , every time i fill one of my textbox, the properties didn't set the value, i put breakpoint in the 'set' part of all my properties but it never breaks anyway.. (the 'get' part is good, it read my property value when i load the form). so i just had problem in my 'SET' Part.
8. I think i had checked on my variable (word, case sensitive,etc), no problem.
I'm sorta newish to VB.Net programming, and in the program I'm working on (VB Express 2010, Windows 7) its as if everything has frozen. When I make changes to the code or the designer view, then run/debug the program, the changes don't get saved. For example, I put a random button on the form, saved it, ran it, and when I ran it, the button didn't appear.
im trying to learn ado from vb and i noticed some difference in the codes from the sites url...may i ask why the other tutorial didn't bother of using the functions open and close for the oledbconnection?
On Windows Phone 7 to get the current control one would use
FocusManager.GetFocusedElement()
Wherea on Winform it is just ActiveControl.Why use 2 semantics which is a nuisance for portability ? Is there any difference of behavior you can see between the two ? If yes that makes sense, otherwise that doesn't.
I am new to vb.net and I have looked at other topics. I cannot find the answer I need. OK I have a combobox named cboRaceDesc and five checkboxes (CkRaceAfricanAmerican, ChkRaceAmerican Indian, ckRaceAsian, ckRacePacificIslander, and ckRaceWhite). I was going to post an image, but I cannot.cboRaceDesc has two options...Hispanic and Other. If the user selects Other then they have to choose one of the five checkboxes or it will raise an exception when the record is being saved. I am assuming I would generate the code under the "save" button. I know I need to gather the following information in my code:
If cboRaceDesc.SelectedValue = Other Then <I am not sure how to code the logic regarding the checkboxes> <I know I need to use multiple else/else if statements> <I know towards the end I would generate the exception> End
Can anyone help me fill in the blanks or point me in the right direction?
I am currently developing an application using VB.NET in which I am using the REST WebServices. I have been able to do the basics with REST, however, I have not been able to add an attachment (more specifically upload a file, using REST which gets attached). I have done extensive research online, but so far I have not been able to find any working examples in VB.NET. To actually upload the data I use System.Net.WebClient. The following VB.NET code does the important work:[code]As you can see, the postString is converted to bytes and then uploaded to the server. However, I do not know where or how I should be posting the raw attachment itself. The documentation for the service we are specifically using states to use a variable "attachment_ 1," which I added to the postString variable, but I am not sure what the next step should be. Should the file be converted into bytes and appended to the postBytes variable?
i am getting an input from the user and i m checking in try catch statement. what i want to do is when the exception is caught i want to stop executing the rest of the code. my code is as below
Public Class AddForm Private Sub Add_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Add.Click Dim inc As Integer[code]......
When I start typing a variable (or whatever), VB pops up a little box with all possible variables starting with the letters I already typed. It's really smart!
However this option has somehow been disabled. How do I enable it again?
I need to send over data to a REST API.I have a dataset with a datatable with the nececessary data. The data has to be in a specific format. I have a .xsd file with the format needed and a .xml file with an example.
I have this code within a button: If TextBox1.TextLength = 3 Then MsgBox("Please enter 3 numbers followed by a letter. For Example 001A")TextBox1.Text = "" Me.Refresh() End If Although if the user enters 3 numbers only, I want the rest of the code in the button to be ignored so that it doesn't proceed.
For this program im using http method post to recieve messages from the server, when its waiting for a new message to be sent it locks the program up. No biggie, ill just thread the sub... Bad idea... I also have functions "send", "Connect", "disconnect". All on threads... i looked at task manager it started getting up to 100+ threads. I dont know much about threads but that just seems way to much. they will die off and the count will return to 20 but id like to find a different way of keeping the program from locking up but not having 100+ threads.. Little off topic: i used a user control. The only problem now is on the tab, its not anchored with the rest of the form... how do i accomplish this?
If I use the exact same thing but I say txtFirstName.Text = "found", Then "found" shows up in the text box when I click the button and the first line is true.
That tells me that there is a value in .strEmployeeNumber, and it is in the *same* array as .strFirstname, so there should be a value in .strFirstName as well. But for some reason, when I click the button and the first part is true, it overlays a string.empty and clears the box instead of the First Name.
I've just created my first web application project.Now I want to add a RESTFul service.It can be pretty simple, all I need is to pass 1 string (userid) and 1 integer (objecttype) and return a json result.
I'm just curious that how a month is calculated in the rest of the world because Differences in Months between two dates are calculated differently. In our Insurance Company, we calculate a month as below:
