Save Button Doesn`t Work Properly?
Jan 30, 2012
I wrote a program which is editing data from database. I used few tutorials (I`m beginer) and everything is working fine(I can make changes in datagrid). but when I`m trying to save changes made in dataset(e.g. save added record) I can not to that (there are no changes in my access database, but inly in datagrid)what is interesting when I delete record - changes are saved and record is deleted from db. where is my mistake? what is wrong? maybe some tips what can I improve in this small program?

i've got a problem here whereby my ctype doesn't work.firstly, to replicate my case briefly, i've created an extension of control class
[code]...
father.getheight 'compiler writes: Panel class doesn't support getheight, but I've already converted it to a Control with CType!end sub of course if i dim father as Control it works perfectly, but in my case father may be other objects as well that aren't controls so I had to dim father as a general object, is there a fix so i could properly convert father into a Control object?

I'm trying to set the tab order on my form and no matter what I do, it doesn't relearn the new tab position after I change the index. It almost seems like the form is locked.

I have made a text editing application and, as you might have guessed yourself, I needed to add save features. Well, what I have implemented so far is the ordinary "Save As..." feature which I made by using a common SaveFileDialog. Now it's time for the hard part. I need to add the "Save" function located in many Windows applications (Notepad etc.). This is what I'm working on at this moment but it doesn't seem to work.

Assume an application uses the Dim SalesArray(1 to 10) As Integer instruction to declare an array named SalesArray. The array contains 10 sales amounts. When the user clicks the DisplayAverage button on the form, he or she should calculate and display the average sales in currency format. The code for the DisplayAverage button doesn't work. Fix it.

I have a form that has around 4 txtboxes. Data is inserted into these boxes and then a "Save" Button is pressed. I have a GridView added to my form and want to view the entries. The issue I am having is that when I click the save button the data doesn't show up in the DataGridView until I close the application and then re open it.

I am a bit stuck with coding my save button and combobox.My entire form is ready, database is linked.All fields from DB are linked to their textboxes on the form.But i just ran into a big wall which i cant seem to break down.My save button, which is used to save the content from all the textboxes on the form to the access database refuses to work.The other this is, i want to use a combobox on my form to view the already saved entries in the access database.I think a combobox works for that, but i am not exactly sure how to pull that one off.

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

So I have a csv file:
[Code]...
My problem is when i use this schema.ini, the 9th, 10th and 11th column of the second row of the csv file doesn't read properly if there's a special character in it (it supposed to be telphone number), i think because the row above is returned as a number(integer) because it's pure numeric:

I have an application that runs perfectly on XP. When I run in on Win 7, it works perfectly when I run it in the IDE but when I deploy it, the application starts OK but some of the functions don't work as they should. I know it could be anything but does anything stand out?

For some reason, it seems that the outer block doesn't seem to update recursively, as I expected it to. I want the loops to add all directories within "C:UsersDrise"to the array internaldirs(). Any advice on the correct way to do this, as it seems I'm doing it improperly?
Static internaldirs() As String
internaldirs.add("C:UsersDrise")

I am using a backgroundworker to start ffmpeg and trying to use a progressbar.ProgressBar1.Value = e.ProgressPercentage does not seem to work probably because the way ffmpeg uses standard error to report progress. I think i could use the output text to do the trick. the output.Seems stream 0 codec frame rate differs from container frame rate: 1000.00 (1000/1) -> 29.92 (359/12) [code]

Basically my script doesn't properly close Word, and it still remains open. Then when I try to run the script again it says its Read-only as its opened..What I need it to do is - put the TextBox1 info onto the DOC - and print it. I don't want it to save, as it's a template. I've tried saving it somewhere else as a "temp" to get rid of this read only but it still doesn't work.Another issue also is that it's trying to close the document before the printing dialog disappears, so I've had to put a timer

Dim str1 As String = Label1.Text

May I also add that the label i'm checking (the text inside it) has no spaces, i don't know if that makes any difference.

I've already found evidence of another having this problem. You can see this on this post by someone else:
http:groups.google...096b3fcaa?pli=1
The problem is that when one navigates the combobox via the keyboard, the combobox's information doesn't update. If you click a value with your mouse, though, everything works wonderfully. The link I've mentioned suggests changing the binding from the Text property to the SelectedItem property. I'm very deep into this project and it would be a bit of a nuisance to change the setup so as to allow it to be bound to the SelectedItem property.What I'm wondering is whether or not I can detect the user changing the selected entry in the combobox and tell VB that they "clicked" the value, if that makes any sense.

End A statement which as far as i know doesn't close you program properly and hides errors. Right now i'm being forced to use end because i don't know how else to close my program properly. I'm not sure where my problem is but some of you should be able to fix it. I'm trying to make a game using directx with a game loop. This code is the skeleton of what i'm making.
Public Class Form1
Private ProgRunning As Boolean = True
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load
Me.Show() 'Make the form appear
Me.Focus() 'Give the form focus
[CODE]...
This code runs alright because end is being used but if you rem end out the error which it's hiding comes out. The error is "Object reference not set to an instance of an object." I'm not totally sure but i'm guessing that the error is refering to the form.

I'm using the IsBusy property to determine when a backgroundworker has completed. In the RunWorkerCompleted event I assing the result of the RunWorkerCompletedEventArgs to a public variable within the module where the backgroundworker events reside. The trouble is, the IsBusy property occasionally becomes true before the public variable gets assigned the value of the RunWorkerCompletedEventArgs. I experimented with putting a Threading.Thread.Sleep(10) after the IsBusy property becomes true and it seems to fix the problem. But it really doesn't seem right that I should have to do this. What is wrong here? I have placed the backgroundworker events in a component that is instantiated from the windows form, instead of placing the background worker events within the code of the form itself.
Here is my code;
Function SendAndWait(ByVal IntegerArray() As Integer) As String
Component.BackgroundWorker.CancelAsync()
Do While Component.BackgroundWorker.IsBusy

I'm working through a programming project, which should be quite easy but im stuck right at the start (relatively new to VB). I have a textbox (named textbox1) and a checkbox next to it. I want the checkbox to be ticked (.checked) when ever the value in the textbox is between 1 and 100, the checkbox to not be ticked when theres nothing in there, and for it not to be ticked when the value is < 1 and > 100. Figured a case statement would be the easiest. (this piece of code is just a validation check, basically in the real thing the user would have to enter in a value between 1 and a given number, and need to tell the user if that value is valid).
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
Select Case TextBox1.Text
Case Is = ""
[code]....
But what happens is, if I enter in the value 1 in the textbox, the checkbox becomes ticked, as it should. It tick with any values between 2 and 99 (any number not starting with 1) but the checkbox becomes ticked again when the value is 100. For any other range, say 1 to 70, the checkbox would be ticked if the value in the textbox is 1 to 7, or any number starting with 1 or 7, but not 8 or 9, or any number starting with 8 or 9.
