Form Doesn't Display Until File Is Done Converting?
Aug 1, 2011
I am writing a VB.Net program. In my Main form, I ask the user if he has an old file that he wants me to convert first. If he says "yes", I start converting the file, loading the records into an Access database. I want to update a line on the form, showing my progress. But the form doesn't display until AFTER the entire file is converted (and loaded into the database). That means the user has to look at a form for 2-3 minutes without knowing if the program is actually processing, or is hanging up (looping).
I don't understand what is going on, and so I don't know what to do about it. I'm sure SOMEONE with experience has come across this situation before.
I need to quickly demonstrate a project and decided to create a user control that is connected to an Access database through pure simple data connections (create the dataset and drag it on the control.)When I build the project and add the usercontrol to panel control on the main form, no data is shown in the datagrid.When I add the data components directly on the main form, the data is displayed properly. why I can't get my databound user control to display the data on my main form?
In trying to test some graphic features, I am trying to get them to display on load so button doesn't have to be pressed. I used the following code as suggested from forum. Message boxes run but ellipses aren't displayed until button is clicked which is what I am trying to avoid!
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Button1.PerformClick() Button1_Click(Nothing, Nothing)
I am using VB.NET 2010.I have a Queue to save different data (which all come from a class of mine) as FIFO Now, I want a Function to count the saved classes in my Queue, but this isn't working
My Code look like this
Private Function QueueSum(ByVal myQueue As

TryCast seems to be wrong. - because the Intelli Sense tells me, that "SATZ" isn't declared.
Inside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.
I am working on a project where I have a signature displayed on the screen that is drawn via code based on data that has been transmitted from another device. This is from one of the samples from MS. The signature displays on screen just fine but I need to convert this to a bmp or jpg so I can save it to disk and/or print it on a report.
Code: PrivateSub DrawSignature(ByVal g As Graphics) ' background g.Clear(Color.Cornsilk) ' border g.DrawRectangle(Pens.Gray, 0, 0, pictSignature.Width - 1, pictSignature.Height - 1) ' return if don't have a signature [Code] .....
I have tried creating a new bitmap from the image property of pictSignature but it is empty even though it has an image displayed on screen. This is the first time I have tried to work with this type of coding and am totally at a loss as to what I need to do to get a bitmap from the data.
So basically, I have this RSS feed in hand. I converted the RSS into XmlDocument by the following:
Public Function GroveHallFromRss() As String Dim webClient As System.Net.WebClient = New System.Net.WebClient() Dim ourUrl As String = "http://abc.123.org/RSSSyndicator.aspx?type=N&
[Code]....
So I'm wondering how could I display the converted RSS as any other XML file with the nodes styled. (but not rendered and displayed by browser as RSS, but only styled XML)
I am using DevExpress GridControl to display information from my database through a stored procedure (ie. SELECT * FROM aTable). Unfortunately when I run the program it doesn't display any of the information, columns, etc. It displays an empty table. I know that there is information contained by the GridView though as I have print statements that return the row count. Specifically:Console.WriteLine(GridView2.RowCount) ' returns the number of rows that should be displayedConsole.WriteLine(myTable.Rows.Count) ' returns the number of rows that should be displayedWhat should I do so that the actual data within the table (DataTable) and the DataView is displayed to the user. I know the row count is correct as when I add/remove a record the row count correlates by incrementing/decrementing.
I'm making a hangman game right now, and the way it works is: It takes ten words from a text file and puts them in an array.It's supposed to take one of those words randomly and change all the letters to asterisks and display it in a text box for the user to start playing.I'm currently having trouble with converting the whole word into the right amount of asterisks to display.As you can see, I've already started trying something with a for next loop to go through the word and replace each letter with asterisks.But I'm not sure of the exact 'wording' of it.
i posted about how to transfer file and i found a thread explains it with sample. Now how am i able to display it in a form the file transfer, the icon the name and size. And the user can click it .
I have a VB 2008 application with multiple DataPicker fields. The data is binded to SQL database. On the form load I set the checkBox for each date to false if there is no date in the field. Noticed that if I make changes to some dates for record 1 in the table, save it and scroll to the next record - I see the date that I just changed for record 1 - also on records 2 and 3. Why is it happening? I don't have that problem if I use text fields to display the dates. I had encountered the same problem with different project and just switched to text boxes. With this new project?
I have a SQL stored procedure that I bind to a Silverlight Datagrid. That works ok, the problem is when I use the same stored procedure to bind a different dataset to the same grid, it doesn't display the new data, only empty columns from the last dataset that was bound. What is going on here? I tried to set the grid = Nothing and I tried using Datagrid1.columns.clear() but that didn't work.
I am building a form that will load individual items(from individual files) or a catalog of items(from a list of items). I then click the item I want to use to select it. Everything works correctly, when I click an item it selects the correct stitch. The only problem is, it doesn't display correctly when I load from a catalog. I can open individual items and it works fine. When I load a catalog it doesn't display the images correctly.
I am developing a application where I have 1 parent from (windowstate of Parent from is set to Maximized) and 2 child forms. In my Parent form I have a menustrip with following code to activate child -
The form is an About Us form so has nothing on it only a text box and a OK button.
[Code]...
Why won't the button close the form? I'm puzzled, I tried another button just in case with the same result. UPDATE: I set a break point on Me.Close() and it isn't reaching it when I click the button, I created a new button and the same thing happened.
I have a problem in timers, I want to display 2 forms each one after 3 and 5, how to do that? I mean when the first form appears, after 3 seconds another one will appear, then after 5 seconds the second will appear. I have a code where someone gave me here but its for message box only, thus I modify it to put a form still does not work. Here the code I put in the timer below:
Private Sub frmblabla_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load tmrnote.Start() Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....
I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.
on my program i have an activation in it and in order to activate the program you need to enter a code that is stored in the settings. so i was looking through my computer and i found the programs config file. and so I opened it and i found all of the codes for the activation. I need to find out how to make the file so the user doesn't have access to it and then how to move it to a more hidden place in the C: drive.
It is saved on my desktop for easy access.I can close the program. I can click the solution to open it right back up, no problems.I then zip my file (also to the desktop)
My problem: I moved the original file (Project A) to another folder and extracted the unzipped Project A onto the desktop. When I open the new Project A's solution file, nothing happens besides VB starting up. It doesn't show me anything.
I've got a problem in Importing Text delimited File to access Db , I always get an error "No value given for one or more required parameters' while execution [Select Into] Statement

I am using memorystream to get and store images into sqlserver 2005 table image field. This process is working and I am able to display image in picture box. I need to be able to store PDF files into the same field and be able to display in a picture box.
I have just received an interesting feedback from a VB.NET customer using our product - for some reason intellisense hidden a certain enumeration value.After a small testing I have found that this is likely a bug in IntelliSense: [URL]..To be honest, I did not expect this problem with such a basic stuff like this. Have you seen this in the past? For me, it doesn't work in all VS versions...
Anyway, feel free to track this issue if you are coding in VB.NET.
I converted a Vb.Net Form (which was previously written in vb6) with sharpdevelop to c#, now i am getting error that no suitable main method can be found.
