[[code]I have this issue where most of the rows in the table do not fill in the data to textbox2 and any edits made in the text box when this happens do not commit to the underlying datasource.When scrolling down and back up the datarepeater different records seem to be shown each time the data on the left is correct in the standard DGV ... it's just the data repeater that doesn't work.
View 1 RepliesI have made a form that consists of textboxes nested in groupboxes nested in tabpages. I want to check if all textboxes are empty in every groupbox and even if the controls from a groupbox in a groupbox are empty.When they are empty i should not create an element string for my .xml document.Below is the code that I have at the moment. I call it with the form as the parameter.
Public Sub recurringControls(ByRef ctl As Control)
For Each c As Control In ctl.Controls
If c.Controls.Count > 0 Then
If c.Tag IsNot Nothing Then

I am having trouble binding data to data repeater when I use ISyncResult.This is what I am doing.There is a button inside a Update Panel that gets the input from the user and calls a function that returns a dataset that I then bind to data repeater which is also inside a update panel.What I did is that I made a delegate to this function, now I am calling this function like this
[Code]...
I am having hard time figuring out why the data repeater is showing no data.While debugging this I see that the dataset is getting the data and is passing the the "ds" but nothing is showing up on my page even though the data is being passed to controls inside data repeater while I am debugging.
I have been making a text based noughts and crosses game and trying to convert an alpha grid reference into a number to run the logic sequence that decides whether the an input is valid. I am using the asc command to convert but it just keeps putting up the error: Conversion from string "a" to type 'Double' is not valid, when it reaches the line If (Asc(Left(choice, 1)) >= 65 And Asc(Left(choice, 1)) <= 67) Or (Asc(Left(choice, 1)) >= 97 And Asc(Left(choice, 1) <= 97))Choice is the input and has already been checked for length, whether it contains an alpha and numeric input (and where they are) and whether the numeric value is valid.

But for some reason it is going into the then block when the handout1 is nothing in the database... I have tried a hundred different ways of checking but it is still trying to run that line of code even when there is nothing to assign to it....

I am at college and am creating an app. however i have two main problems within my app. my app is a pizza app which will allow staff within a pizza shop to send the orders to the kitchen (this is just a listbox).but, the math doesnt work, the correct pricing isnt being displayed in the label for the orders for some reason. I have tried different ways of writing and placing my code but the result is always the same. also, i have five customers per table. if i select all the customers orders and click on send, only customer two's order will be sent. not any of the other customers, but if i just do customer one on its own, it works.

I have a context menu strip associated with a listview. Everything work just fine however one of my menu options on the context menu strip has a pop-out menu (you know, you hover over the selection, and another menu strip expands out).I can seem to get these to work correctly.
Public Sub ReleasedToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ReleasedToolStripMenuItem.Click
FileEntries(ListViewSelectedIndex).Status = "Released"
[code]....
So I changed my sub to read as the one VB created, and still didnt work. So I went back to edit the context menu, double clicked "Reserved" menu items, then VB creates a sub w/o the _1 (like I had before).Also the check-box status for these menu items works fine.
I have the following function in my program:
Format(Now(), "yMMdd" & "hhmm")
in 2009 it produces 912311200 for 12/31/2009 12:00
in 2010 it produces 1001011200 for 01/01/2010 12:00
It is giving me a 2 digit year. How do I get a 1 digit year?
I use the following statement to position which row to update;
Dim salonToUpdate = (From r In db.Salons _
Where r.StoreID = storeID _
Select r).Single()
If fileDate = #1/1/1900# OrElse fileDate = Nothing Then
SalonToUpdate.LastDownLoadDate = TableDate
[Code] .....
I've double checked to make sure none of the dates are invalid or null, but when the bolded statement executes, the following sql runs through the trace:
exec sp_executesql N'UPDATE [dbo].[Salons]
SET [LastDownLoadDate] = @p0
WHERE 0 = 1',N'@p0 datetime',@p0='2008-01-04 00:00:00:000'
Of course it's going to fail if LINQ is passing in where 0=1 every time. Shouldn't it be using some unique row identifier, (in my case, the salon id), to update the specific row?
i have a text box that has a max length of 5. when typeing into that text box the character input stops on the 5th character. if i set teh text property to a sting that has more than 5 characters the text box accepts the string. in vb6 i think that the text box would truncate the string to 5 characters.
does anyone know of a way to truncate, or get the text box to only accept the maxlength of the text box

I have an AsynchFileUpload on my page and for some reason when I try to use it to save the file to the server it falls. The control will allow me to select a file locally and it displays the local file path in its text box, BUT when I then click a button on my page which I am going to be using to submit all details then upload the page everything goes wrong and I get a Null Ref Exception from the AsynchFileUploader.

It seems that the filename is being lost somewhere after the button is clicked, or just never stored

I'm trying to see if the microphone on a PC is working correctly by utilizing the SpeechRecognitionEngine class.I'm using the following
VB.NET
Dim RecognitionEngine As New SpeechRecognitionEngine(New CultureInfo("en-US"))
'Dim synth As New SpeechSynthesizer
'synth.SpeakAsync("Microphone")
[code]....
When I run this code, the microphone runs until it detects a sound. If the room is silent, it never stops. At least so much as I can tell so far.But I need a way to detect when it can't detect a sound within a specified interval.I looked on MSDN and all I could find was a property called, BabbleTime. I can specify a TimeSpan that will time out the speech recognition, but from that, I can't determine if it was the timeout that caused the code to continue or if it detected sound.
I have some update panels on my page that do some asyncpostbacks to keep some dropdownlists correctly populated. My problem is that on my page i have an HTML input that is handling some file uploads. With the AJAX on the page with asyncpostbacks, and while i step through my code behind, the files arent being uploaded. Using a postbacktrigger (non-async) is not possible because of my layout.
Here is my code:
<div id="divFileInputs" runat="server">
<input id="file1" name="fileInput" type="file" runat="server" size="50" style="width: 50em"
onfocus="AddFileInput()" class="textbox" /></div>
[code]....
When I put a breakpoint in at the declaration of service and then check the value of "files", the count is 0. I am expecting it to be 2 when i have one file uploaded.
I have a problem where I have maskedtextbox's for Time only that do not show correctly in the datarepeater. Outside the repeater they are fine. In the datarepeater it shows the date instead of the time but in the masked format.
For Example:
11/23/2010 07:00:00AM Shows as 11:23 instead of 07:00
I have a database object and one of the items is an image which is stored on the net. i wish to display this image in a datarepeater. I have the data repeater setup correctly and the item in question is a picturebox. here is a basic idea of what i am trying to accomplish
For Each itm In joblist
Dim j As New Job
j.ID = CInt(itm.ID.Value)
[Code].....
Well i ran this and it doesn't display anything on the datarepeater. I believe this is because the image hadn't been placed on the control before i take it off, but i would have expected that it would be there for other items in the list but it isn't. I then got thinking i should put this onto an imagelist so i dropped an imagelist onto the form and realised i still would have the same issue as i'd be placing an empty image onto the image list and would have the problem of taking it off so abandoned the idea.
I have got a dgv which on clicking a cell or row triggers the row_enter event, this in turn fills a list which is then placed as the datasource for the datarepeater. Heres the event which works within a dgv
Private Sub dgv1_RowEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgv1.RowEnter
Dim NameList As New List(Of TestList)
For Each item In Example.Item(e.RowIndex).Names
[code]....
Now this is all well and good but i need a way to do this using a datarepeater. I have tried about 5 events to get something like e.RowIndex and have been unable to find any event that would let me use this routine?
I'm seriously about to abandon this DataRepeater. I don't want to. I want greater design control than the DataGridView. I've played with various Events for days and have settled on the CheckBox.CheckChanged Event.
What I'm trying to accomplish: My Bound DataRepeater has an UnBound CheckBox in each DataRepeaterItem.When the user 'Checks' the CheckBox, I want to change the value of a NumericUpDown Control to the value of a hidden, Bound Label.
[Code]...
This causes other, seemingly random, DataRepeaterItems (Rows) to also become Checked and thus it's NumericUpDown value to change.Am I going about this from the wrong angle? Can't see the forest for the trees?
I 'm having no trouble coding, I'm back to my initial printing problems. The program printed Avery labels in a variety of sizes. I created the label templates on 8.5 x 11 forms and then printed the forms. This cannot be done in VB 2008 for a variety of reasons:
1) The form size cannot be larger than the screen size I got around this by creating a new form class that matched my dimensions.
2) printform only does screen shots. This was a major barrier. First of all I can't get printform to print my custom form because it's not a member of system.window.forms.form, it's a class in system.window.forms.usercontrol. However, even if it was in the correct class, it wouldn't work correctly because printform in VB.net, does a screen capture of the form and then reduces the image on the printout.
So that is my dilema. I do not know how to use the reporting tool, but I can see that it must be binded to a database. Although my application does use a database, I want to be able to massage the data before printing it. And the application does more than just print labels. There are also custom reports that need to be printed.
I'm building an application that outputs a list of usernames to an HTML document. I'm using this to generate a string:
For y As Int16 = 0 To intBuddyList - 1
strBuddyListHTML = strBuddyListHTML & strBuddyList(y) & "<br />"
Next
The resulting string is then put into an HTML document. The problem is, when I load the document, the brackets are displayed literally. When I view the source, I see this:
buddy1<br />buddy2<br />buddy3<br />buddy4<br />tbuddy5<br />tbuddy6<br />
Is there a way to preserve the brackets in the HTML tags?
