Force Form To Refresh?
Sep 28, 2010
I'm having an application which has to perform exporting and importing data. At the moment he runs those functions, I want a form to popup with an animated gif, so my client sees that the application is still running.But the animated gif stops sometimes, because he is busy doing stuff (like copying files, etc...)Is there a way to tell the form to refresh automatically every 0.1 sec, so the image runs fluidly. I tried to put a timer in my form, and start the timer as from the form is shown...the timer_tick says he has to refresh, but he doesn't want to do that.

The application I'm developing does some file management chores, such as renaming and deletion of files. I have noticed that often after a file is deleted via code, it is still shown in Windows Explorer although it doesn't exist anymore. A refresh (F5) solves this, however I wouldn't want end users to have to press F5 every couple of minutes when using the application.
Can a refresh of all open Windows Explorer windows be requested via code? Moreover, can the refresh be requested only for windows displaying a particular location? I've thought of getting all open windows, filtering them and then sending the F5 keystroke, however it sounds a bit like overkill. Any easier way to do it?

Is there a way to force a form to reload itself? The reason I ask is I have a listview that shows the data from my database. You can add information to the database from another form but when you go back to that form the information is not updated because the information updates on the form load. So my question is there a way to just do the form_load event again?

I'm fairly new to VB programming. I have a control which is mounted within a form. I need to implement a callback, so that the control can make the parent form do something. My plan was to create a MustInherit class with MustOverride methods, and make the form inherit the MustInherit class. However, Visual Basic tells me that the form cannot inherit more than one class, which means that it can either inherit my MustInherit class, or System.Windows.Forms.Form, but not both.[code]...

I'm programming a Minesweeper clone in Visual Studio 2010, with VB.NET, as a Windows Form Application, and I'm having trouble with the Game Won and Game Lost forms. When I show those forms, I want the game form to still be visible, so that the player can see where the mines were, but I don't want the game form to be enabled until the Game Won or Game Lost form is closed. Exactly like Windows Minesweeper does when you win or lose.

1. How do I force the Form to change its title through code? I tried: Me.Name = "New Title" during a button press, but that didn't work.
2. How do I make it so a form cannot be resized by the user at all? ie. they can't drag the sides.
3. I have made it to when I save in my application the status bar displays "Save Successful". How would I make it stay with that text a few seconds before displaying "Running..." instead?

I have a parent form that has a combobox. Whn the form loads I get the data from the db and bind to the combobox. that works fine and here is the code I use in form load to cause this to happen: [code] Now if there is not an Account Type, I have a button that will pull up a small form to allow the addition of an account type. The popup form adds the data back to the database just fine, but I am now trying to get the combobox to refresh its data. So I call a public Sub that is located in the parent form to from the popup form to accomplish this task and I have walked the code and the sub is called and appears to work correctly, but the new data never appears in the combobox. Here is my public sub that i call to try and refresh the combobox on the parent form. [code] But when I go back to the parent form, the combobox is not updated with the new account. How can i get the combobox to refresh from the database with the new data?

I am working on VB.Net. I have a sub form with a datagridview, that is being loaded with the criteria taken from another form. Hence this form is called with parameters.
Here is the code that calls the sub form.
Code:
where ds is the dataset to fill the datagridview and rb is the string from a radio button on this form.
Here is the code in the sub form.
Code:
Now, I need to refresh this sub form every -- minutes, depending on how the user wants it to be. For this I have given a NumericUpDown control to select the mins. All this works fine. But how do I refresh the dataset and the datagridview?

I want to create a simple form with 2 buttons, one to end the program and one to log the user off, I have done this successfully and have everything looking and working as it should. However, I want to force the user to pick one of these buttons before using the machine, my idea was to trap the mouse in the form so the only thing the user can do is select a button. My question is how can I do this?

I have a component which hooks up with the paint event of assigned control and draws on its surface, Whenever i make any changes to the component i need to resize the form or control at design time in order to see the changes.
I want to ask if there is any other way to refresh the contents of a control at design time which forces it to redraw.

When multithreading in VB, if you close the form while different threads are running, the process itself will not end. Is there a way I can force all threads to end, or end the process like in the Task Manager, when the form is closed?

I have created a simple VB.NET application with one form and a few modules. When a user clicks on a run button of the form the application starts and goes through differet cycle, while updating the user on status bar, runs for less than four hours.
The application works fine, it gives desired result. However, it is not able to refresh the user form, meaning status bar remains same after some time (it suppose to increment). Even when I take mouse on the form it shows timer symbole instead of default one.
My application commands another device using GPIB. Basically, PC running my application commands the device. If I look the display of device it gives correct information.

I have a form, with a datagridview. I can see the data and the related records in the DGV.I have another form that this one calls to add a new record. I need that because there are some specific parameters i need to control. But when the focus returns to the original form, I can't see the new record, even though it is there (I see it in the database).If I close the form and enter again I can see it, that is not what i want.How can I refresh the tables after the other process adds data to them?

I'm using Mysql database and Visual Studio 2005. I've got a form with datagridview, After making the changes in the data, it is saved in the database. The data gets saved in the database, but the modified data does not get displayed in the datagridview. Only if I close the form and open it again, the changes are displayed. I want to provide a button (refresh-button), which on clicking will refresh the datagridview, so that the modified data is displayed without closing the form.

Been playing around with this and simply can't get it to work
I've got a form and I've created a button called refresh. The button is meant to do exactly that. What happens is that when the form loads, it checks the database for values. If it finds values, it creates a dynamic edit box related to the value.
I open the form and it paints accordingly and as I expect it. If I delete a value from the database then click the refresh button, it should re-draw the form and paint the background grey. The logic definitely works because I trapped the bit of code and it does hit the part where it's meant to set the background grey.
Now, I'm not sure I'm refreshing the form properly because all I'm doing within this sub is calling the form on load event: formLRQuadrantSchedule_Load(Me, New System.EventArgs)
This seems to work logic wise, just not doing what I want. So, I tried this (amongst several other things):
Dim dynTextBox As New TextBox()
Me.Controls.Add(dynTextBox)
With dynTextBox
[Code]....

I have an app that opens up 3 forms. 2 forms have a datagrid the other form has book lending details. The datagrid forms are for books in the library and books that have been borrowed.
Both datagrid forms will be open as shown in the attachment, how do I refresh the "Borrowed Books" datagrid form from inside the form that has the "Book in Library" datagrid.
So far I've been able to update the "Books in Library" datagrid because control comes back to that form after the details form closes but since the "Borrowed Books" form is still opened up, we would like to refresh the datagrid on that form.

I am trying to update my form once the delete button is clicked. There are several fields like Name, Date, Date of Birth and so on. Once I delete record I want the form to automatically load with new / updated data. This form fetches data from MS Access using OLEDB. Once when I close the application and reopen then form will be updated with new values. But I want this to happen once the form loads after deleting.[code]

got question on using windows forms in visual
what i have going on is on one form i have a calendar that is for the month of may. when you click on may 1...it opens a form with some combo boxes and a gridview that displays the choices from the combo boxes.
my question is this..
can I just link all of the other 30 days in may to go to the same form or do I have to make 30 duplicate forms LOL...i know it is a kinda silly question but I really dont know.
It would be a travesty if the user were to click on may 2...and get a form all filled out from may 1...*blush*
Secondly if i were to have a calendar control on the form that may 1 is pointing to (at the moment I dont) how do I get the calendar contol to reflect that it is may 2 and not may 1??
this is not for a web site it is for a tire shop here in town, and it is the first project that I am doing..so it is kind of important to me.

I'm trying to figure out how to make a dynamically scaling/resizing 2d chart on a form as my 1st trip into graphics. Most 3rd party addons/DLLs are of no use to me as the bank I work for is unlikely to allow any of those to be used in my projects.
