I've created a "Loading" borderless Form that's displayed when loading records etc. I'm using the following to keep the loading dialog centered within it's parent.Works great except fo when the form is minimised estore- The loading form appears instantly while the parent (Owner) maximises with the usual VistaWindows 7 animated maximise.
What would be the best method to prevent the loading form appearing before the main form?

Imports System.Runtime.InteropServices
Imports System.Diagnostics

The program is in foreground on click, but fails to maximize/restore.

View 3 Repliesi'm making a vb aplication (only my second one so dont be to cruel) and i'm just wondering how to make it so that when somebody closes my aplication down and open it back up it restores it to the same state, i've had a look on google and the only thing i can find are how to remember the size and position of the form using the registry and also using flat file databases to hold the values of all the text box's but is there an easier and more elegant way

View 1 RepliesI am checking to see if a textbox contains a number, or is null. If it is non numeric or null a message box appears asking the user to input the proper value. When the user clicks OK on the msgbox the program will continue to execute the code. I want it to stop executing the code and revert back to its default state as it would be if you just opened the program. What is the command for doing this so I can add to the if statement?
Dim numCheckV as boolean
numCheckV = IsNumeric(Vinput)
If numCheckV = False OrElse TextBox1.Text = "" Then
MsgBox("Please enter voltage!")
End If
Essentially what I want to do is copy a WebBrowser object such that I can do the equivalent of "Open In New Tab" or "Open In New Window" actions, maintaining any posted data. I don't just want to navigate to the same URL as in the original WebBrowser object, rather I want to repeat the HttpWebRequest.
View 1 RepliesHow do you restore a dataset to the previous state before updating the database with a data adapter? I have a concurrency update problem that I believe to be caused by this. The update fails during the update and a rollback command is issued using a SQLTransaction object. However, now the rowstates of the rows that did not have errors have been changed to unchanged. So this record is no longer availible to be inserted into the database. When I updated the value that could not be null and then test the second update which runs just as the first does then I get a concurrency error. The update code is below:

View 18 RepliesI'm trying to start an application an initiate a save by sending Ctrl m + Ctrl a then Alt Gr O to confirm a dialog.

This works great if the window is active and focused, I would much prefer this process to be done silently (It spawns it's own progress dialog) but SendKeys requires an activefocused window.
I think SendMessage is going to be the answer but I cannot see any way of sending the required key combinations?

I know that time delays have been covered before around almost everywhere. however a method that forgoes forcing the GUI to become temporarily non-responsive, is all but a myth, or at least to my findings. i have the need for a GUI program to delay before the next command, however using the current method, detailed following, it causes the desired effect however it dose make it much less polished as when you click anything else on the GUI it goes un-responsive for the directed time. [Code] make a sub called say Tdelay( milseconds as integer) and have it run a loop as many times as the milseconds variable indicates and each time making the thread delay for 1 milsecond and then update the GUI/form in some way, then re-loop.
View 7 RepliesI have a search page in one form(Search.vb) and another form(Form1.vb) to display the details of selected data from the search form.
I already have back button in Form1.vb which returns to some other form say (Action.vb).
In case of searching data it returns to Form1 to modify the selected data, In this case if i press the back button in Form1.vb it should return to search.vb with the details that i entered for searching.
Is there any way to save and restore the form whenever needed with its details?

I am trying to create my own title bar, but left-double-click does not maximize/restore the form; however, double-clicking any of the remaining buttons on my mouse (right, middle, 'forward', and 'back') maximizes/restore the form. This 'feature' is caused by MouseDown event. If the MouseDown event is removed,the DoubleClick event operates as expected.Can both events be used concurrently (at the same time) with out any loss of functionality?

View 3 RepliesLet's say I want to put a 10 second delay on my splash screen before loading the next form or app.I use a timer, but would it be a simple integer value or several different lines of code?
View 3 RepliesI have created an app which has a timer control which, when activated and meets a certain criteria, launches a second form with an alert for the user to review and action. this works just fine. Except.... when the main app is minimised and has lost focus, instead of launching the second form to a normal windows state it opens and sits in a minimized state itself and just flashes. How can I get the the second form to restore to a normal windows state?I have tried form2.focus and tried the windowsstate=normal etc but I'm still barking up the wrong tree.

View 3 RepliesIm trying make my application display my splash screen for 5secs before loading my main form. I have read lots of threads on this and they all seem to point to the following:Add the following code to the New() sub of the splashscreen.
My.Application.MinimumSplashScreenDisplayTime = 5000
I have also seen a suggestion to add the following code to the OnInitilalize event in the ApplicationsEvents file.
Me.MinimumSplashScreenDisplayTime = 5000
I've have tried both ways, and although it successfully makes my splashscreen wait 5 seconds before closing, it doesnt prevent the Main form from waiting for the splashscreen to close before loading. The mainform simply loads over the top of the splashscreen.This thread is exactly what im after but i cant seem to get mine to work.

I have application framework enabled. I have my startup form set to my main form, and i have set my splashscreen in the application tab of my project properties. Im using VS2008.I also noticed that when i clicked on the "View Application Events" button in the application tab of my project properties, the file was blank. I have seen that some other people have had problems with this. I just cut and paste the following code into my ApplicationEvents file. Potentially an issue??? Any reason why the code was not auto-generated to begin with?
