How do I get message box to stop loading new form I have the following code on a button that loads new form
h
If Me.File_Name.Text = "" Then
MessageBox.Show("No DataFile Has Been Selected", "Please Select a DataFile", MessageBoxButtons.OK)
I want to stop loading the form is the message box appears
I have a menu which when clicked will load form which take quite sometimes (although not very long) but the user keeps on clicking the menu and so the "not responding" message appears on the title bar of the app. I am thinking of displaying "Loading....Please Wait" so that users will stop clicking the menu or will wait until the loading of the form is completed. I tried these code but the form is still displayed even if form has loaded completely. [Code] I like to use the same concept also when the user clicked the save button, to tell the user to wait while changes are being saved.
View 36 Repliesan application i developed using vb 2008 express, to fill a web form with data from an access database, one after another when a button is clicked hasn't given me what i expected. the loop was suposed to stop after filling web form with the first data on clicking a button and continue to fill the webform with the next(2nd) data from the database on clicking the button again. Below is the code i wrote

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.
i am hiding a form and showing another form by this bit of
form1.show()
form2.hide()
form 2 contains of a dgv and by the form1 i am editing the contents of the dgv present in the form 2.......
after making the changes when again i show the form2 and hide the form1,then the changes made did not appears in the form2............
i have this bit of code at the form load of the form2:
con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=LibraryManagement.mdb")
con.Open()
[Code]....
now when i close my application and again reload it then then changes that i made appears in the dgv of the form2........
if i am showing the hidden form then at the time of showing it,does the form load event of the hidden form is raised?
or,
the hidden form is already loaded and there is NO form load event and only the form is shown and hidden...
Why my form loads takes time the first time I clicked the menu to load it (I even see not responding on the title bar), but when it is already loaded, I will close it and clicked the menu to load it again then it load fast already....
Here is what I have in my declaration section

I have a form with about 50 controls on it. labels, check boxes, combo boxes. text boxes and so on. Now I have a image on the back ground of the form and have made the checkbox text with transparent back ground so the picture can show through. the problem is that it is so slow to load. I see each one appearing on the form one by one. I have tried this on multiple machines and it does it on all of them. I have tried making the checkboxes not transparent but it still is slow.
how can I allow the form to load completely before it displays it. This is the initial form that loads and shows up.
i'm doing Advance search in my applications(vb.net,MS-Access) ,the results display form is quite heavy so i thought before loding the form i want to show some search icon

Is there a way of stopping the main page waiting for a usercontrol to load before it can finish loading?
I have a usercontrolthat has to do a lot of DB calls which can take a few seconds making the page slow to load. Ideally I'd like the main page to load straight away and then the usercontrol content appear when it is ready.
I believe I have found a solution! I will be continuing testing to make sure it DOES in fact work, but I'm hopeful :) I have detailed how I found the solution in EDIT THREE of the question.
For anyone wishing to know the full background behind my problem and what I have kind of tried as a result of input from this question, see this: [url]
I will be editing this frequently (>3 times a day most weekdays) as I progress my research and situation, so keep checking back if you are interested or have some information or knowledge of my issue :)
Quick Background:
I have this app I have made that can be crashed by changing my screen saver or locking my work station, and in general whenever a WM_WININICHANGE/WM_SETTINGSCHANGE message is sent to it.
If I can consistently crash my app by changing my screensaver, then SOME part of doing that is sending my app SOME kind of message (not necessarily a windows message, I mean message in the most general sense), which in turn is catastrophic to my application. Due to this, I am trying to find a way to block whatever message is causing my problem from being processed by my application. I am aware this isn't the best way to go about a solution, so you don't need to tell me. Look at the backgroung info or ask why if that bothers you (there is a good reason).

View 4 RepliesI have written a very simple Windows Forms App. which copies files from my hard drive to my USB flash drive.The app. works ok, but while it is running (copying files) the title bar displays (not responding).I have an idea this is due to the time it takes to do a large copy.
I have two questions:First, I want to add a progress bar, as a visual indication as to how much is left to copy, but I don't know how write the code required for the progress bar when copying say: C:*.* (including all sub-directories)
Second, to stop the (not responding) message being displayed in the title bar. Would I need to run the copy as a background process? If so, how?

View 11 Repliesi have a pretty simple registration wizard form. this is an mvc3 azor project written in vb.my last step displays a partial view with the user's entered details. since the partial can take a split second to load, the form looks odd until it does - a blank form with a couple of buttons. is there a clean, proper way to display a little loading image/message while the partial is loading so it's obvious to the user he/she needs to hold on a sec.
my code for the register view:
$(function () {
$(".wizardstep:first").fadeIn(); // show first step
// attach back button handler
[code]....
the partial view for now is just a dummy display of the model elements.
I'm trying to show message "Loading..." when a user select an item in the dorp down list.

The method I'm using above is not working. When I select a new item from the drop down list, it works as expected except the message "Loading..." is not showing at all.

I am using a DLL in my application that will probably be experiencing frequent updates. I want the DLL to detect the new version (I know how to do this), load the new version of the DLL into memory, and continue running. Is this even possible? So I need to know how to: Unload the current DLL. Load the new DLL. If possible, do this from the DLL in question. Is this even possible? If not, how close can I get to this?
