View 2 RepliesI am attempting to disable the close button "X" in the controlbox of a form and keep the maximize and minimize buttons. There does not appear to be a way to accomplish this with conventional VB code or using the Form's Properties.
So I ventured into the realm of API's.
I declared the following API Calls and Constants:
Declare Function GetSystemMenu Lib "user32" Alias "GetSystemMenu" _
(ByVal hwnd As Long, ByVal bRevert As Long) As Long
Declare Function EnableMenuItem Lib "user32" Alias "EnableMenuItem" _

I have a form that the user must enter some important information and the only way of leaving of that form is to enter the correct info. By mistake I close that form from the X on the upper right side realizing that my code restrictions on that form was not enough. How can I disable close (X) of that form? I checked the form properties but I couldn't find anything about that just to disable maximize and minimize.

I have been asked to remove or disable the close button from our VB .NET 2005 MDI application. There are no native properties on a form that allow you to grey out the close button so the user cannot close it, and I do not remember seeing anything in the form class that will allow me to do this.
Is there perhaps an API call or some magical property to set or function to call in .NET 2005 or later to do this?

I'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.

I have a need to add the ability to receive SNMP traps into one of my server apps (written in VB 2005). I have setup a UDP listener on port 162 (SNMP trap port) and can successfully get the trap message in a byte array no probs.
The problem is that I have no idea how to make a meaningfull message from this byte array. Does anyone have any pointers / code to either translate into a meaningfull message stream or a better way of adding this type of functionality (without adding 3rd party dll's etc).
When it comes to Backgroundworker's, I just make a total mess, even after reading over and over again the Backgroundworker component info on the msdn site... I have a code I would like to run on the form but if I do it with a simple "Public Sub" it will make the form lag, freeze, until the operation is done. So I try to paste the same code into a backgroundworker, and use Runworkerasync, but I get errors stating that the backgroundworker can't access controls on the form.

View 2 RepliesI have a system on my webbrowser that allows the user to choose their Search Engine out of a selection I organized. the down point is that I have it set so when they click save it will just hide, because if it closes the settings will be reset and not saved. However I want them to save. Here are my codes to the search button:
Private Sub Search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Search.Click
If SearchEngines.RadioButton1.Checked Then
CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Navigate("http:www.google.com/search?hl=en&q=" & SearchBar.Text & "&btnG=Google+Search&meta=")
[code]....
This is the code of save:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Hide()
End Sub
I would like it so it saves when the whole program is closed, so when they start up it's automatically set so they can search on their favourite search engine.
So I am trying to make a program where the user is limited in moving the mouse to a form. I still want the user to see whats going on behind the form but not be able to click on anything but my form.
I tried using this
Cursor.Clip = Me.RectangleToScreen(Me.ClientRectangle)
The problem is that if the user clicks in certain spots on the titlebar...the mouse is unlocked. The machines this is going on has a ball type of mouse so if you scroll fast and click fast enough...it can also unlock.
i want to give the ability for a user to drag an area on the screen that they want and a that area to be print screened. or alternativly they click anywhere and that location is the top left of the box and then when they next click that location is the bottom right of the box and that box is print screened.

I have a simple query that fills a datatable from an Access DB. There are about 1.7 million records returned, so I would expect it to take a little time. At first, the query was a very simple one, and it took a couple seconds to fill the datatable. However, I really wanted the ability to restrict the rows by a certain date field, which meant a single INNER JOIN to a different table. Having written this, I verified that it was correct by copying the SQL string into the query builder in Access. The query, in Access, took a couple seconds to complete. That was comparable to the time I was seeing before I added in the join.
However, in VB, the query isn't completing at all. After 60 seconds, I get a message about a ContextSwitchDeadlock stating that it hadn't been able to transition or pump messages in a long time. Frankly, since the exact code works fine when I remove the JOIN, this seems like it is either a deadlock internal to the Jet engine, or the error message is an artifact of a very long running query. My question is why a query (albeit a large one) is hanging in the VB program when the exact SQL runs in a couple seconds in the Access query designer, and when I remove the JOIN, the query runs in a couple seconds in VB?
