Different Behavior Of The Combobox In .net?
Sep 10, 2010I have a combobox in a Windows form. I set the properties of the combobox as follow:
AutoCompleteMode: Suggest
AutoCompleteSource: ListIems
DropDownStyle: Simple
DataSource: some binding source
Problem when user enter value to the textbox and open the dropdown and filter out the dropdown list. When user mouse click an item in the dropdown list, it will not select the item and paste it to the textbox. User uses the down arrow to navigate to the item and click on the "enter" key and it will not paste the selected item to the textbox. The only way to select an item is using the down arrow key to navigate to an item and then "Tab" away and it will paste the selected item to the textbox.I want to be able to use mouse click or "enter" key to select an item from teh dropdown list.I want to set the DropDownStyle as "Simple" so user can think it is "textbox" and start entering value to it.

Sorting - Combobox - Auto-complete Behavior For Numeric Values?
Feb 21, 2012I have a problem with the auto-complete behaviour of comboboxes in VB.NET (with the .NET framework 2.0).I am using a combobox to type in numeric values, and its DropDown list to suggest possible numeric values. This list is sorted in ascending order, for example {"10","92", "9000", "9001"}.The combobox properties are set as follow:
AutoCompleteMode: SuggestAppend
AutoCompleteSource: ListItems
DropDownStyle: DropDown
Sorted: False
The DropDown list is simply filled like this:
myCombobox.Items.Add("10")
myCombobox.Items.Add("92")
myCombobox.Items.Add("9000")
myCombobox.Items.Add("9001")
When I don't type anything, the order of values of the DropDown list is correct, in original/ascending order. However, when I start typing something, the suggested values in the DropDown list get sorted (alphanumerically): if I type "9", the list of suggestions becomes {"9000", "9001", "92"}.I would like to prevent this behaviour to get the values of the list in the original/ascending order. I can't figure out how...A possible work-around would be to pad with zeroes the values in the list, e.g. {"0010", "0092", "9000", "9001"} but I would like to avoid this.

.Net 2008 IntelliSense Odd Behavior?
Jul 26, 2011I am primarily a C# developer; however, I am currently working on a project for a client who preferred VB.net. I have managed to switch over fairly well, with one frustrating exception. When editing a C# file in Visual Studio pressing enter will select an item out of the IntelliSense window and keep the cursor at the end of the selected statement.
However, when editing a VB file, pressing enter selects the item out the IntelliSense popup AND moves the cursor to the next line. I realize that this is a small thing, but it drives me crazy, because it makes it really hard to switch between C# and VB projects.
I have searched for everything I can think of in Google and found nothing. Does anyone know of a way to change the IntelliSense selection behavior?
VS 2008 Create A Certain Button Behavior?
Sep 9, 2009I am trying to create a button behavior such that when you click the button it fires the click event as normal & runs the code under it. But if you click & hold the button for 1 second then it jumps to a different sub & runs some other code. I got my button working that way for the most part, using a timer & the mouse down & mouse up events. The only issue I have is that after the timer fires after 1 second & I execute my alternate code, the normal button click event still fires when I release the mouse button & runs that code. How can I cancel the normal click event so that only the alternate code runs when I click,

VS 2008 Awckward Behavior From Multiple Form Instances Loaded Into A Dictionary?
Jul 27, 2009Ok I have a project which has a MDI parent. Inside the parent I have multiple isntances of a form load(frmLine1t5). When my program loads it will load a different form(frmSelect) and if I manually load a different form(frmRetests) I can put frmSelect on top of frmRetests and bring one another to the front if it's clicked on(without using the bringtofront method)However as soon as I load a single instance of frmLine1t5 I immediately can no longer bring ANY form loaded into the MDI parent(before or after frmLine1t5 has loaded) to the front. I can only bring them to print IF I use .bringtofront method
View 1 RepliesVS 2008 Manipulating WndProc Messages Causes Weird Behavior When Changing Me.ShowInTaskbar
Oct 8, 2009I am capturing a few system command messages (namely minimize/maximize/restore). Inside the WndProc override I am trying to change the form's Me.ShowInTaskbar value but it is causing weird behavior in that minimization and restoration does not occur properly.Can anyone think of a reason why changing this property would interfere with this? The reason I don't really want to post code is because duplicating the effect takes a bit of code/setup. My initial thought was that changing the property's value is somehow sending another windows message and canceling the one I am currently manipulating. I realize this is a little vague but it's a shot in the dark.

ASP.NET: Backspace Key Behavior?
Jun 29, 2011I'm writing an in-house intranet application in ASP.NET and VB.NET. My 'customers' are beginner to medium-level users. All of our browsers are IE8 and above, standard.The application works great, except for one thing. The backspace key. When a user types an invalid number into a textbox, a RegularExpressionValidator and ValidatorCalloutExtender fire off and notify the user. Perfect. Except that, when the user closes the popup warning and notices the cursor is still flashing in the textbox, he/she feels it's time to hit the backspace key and delete that pesky field value.
Unfortunately, the browser interprets this action as a desire to go 'back' into the page history. My boss is screaming. His bosses are screaming. I have a headache.So, how can I turn off this behavior? I still need the backspace to eliminate characters in the textbox, but nothing else. Company policy here: Backspace is to delete characters from the screen. Nothing more, nothing less.
Different .NET Application Behavior?
Jul 8, 2011Strange vb.NET application behavior/One application e.g. does some recursive operations against a ftp server as it synchronizes a local directory with a remote directory. When this part is finished, recursively I loop through the local directory to compare each individual file with a hash code table file retrieved from remote to be sure the source file and the destination file are identical. The processing speed to me during the coding was really satisfactory, but all over sudden the all over performance has been reduced by factor 3. So what happened was I closed an application named TeamSpeak. As you can guess it took me a while to figure out what was happening. This behavior is reproducible even with other applications like Outlook or Winamp?To make it short: e.g. TeamSpeak is up and running, my application runs 3 times faster than without TeamSpeak up and running ... same code - no changes !!!

.net - Silverlight MaxItemsInObjectGraph Behavior?
Jan 27, 2011I currently have a silverlight application which has silverlight class library. The silverlight class library has a WCF service reference which works as expected for small data. However we have come across a problem which is caused by the default value of maxItemsInObjectGraph. We have tested it with an increased value (called from vb app set in behaviour) and it works however we are unsure how to set the value of maxItemsInObjectGraph when it is in a silverlight class library (as it is only defined in the clientconfig file and no services are added to the client). I have seen posts about adding it to the web.config but this only seems to apply when the service is called directly by the app not by a class library?
View 1 Replies.NET UserControl's MouseLeave Different Behavior?
Mar 22, 2009I have a userControl (.NET 1.1 Winforms) that has a clickable picturebox as a button.Since I have lots of those usercontrols visible at the same time, I thought It could be nice if I just display the picture box when the mouse is over the usercontrol and hide it otherwise.To do so, I handle the MouseEnter and MouseLeave events of the UserControl, hiding and displaying the picturebox. That works fine.But when the clickable picturebox is visible I'm not longer able to click it (the hand cursor is gone and the click event is not firing).After some test, I realize that if comment all content on the MouseLeave handler that do something with my picturebox... this way the picturebox is clickable.I'm not using the correct event?
Here is the code...
Private Sub NodoEstablo_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.pictAdd.Visible = False
End Sub
[code]....
Update:If I resize the picturebox on MouseLeave (just to do something) it works.So far, changing Visible and Location in the MouseLeave prevent me for click the picturebox.
