Picture "biedkrt" - MouseHover Error
May 2, 2011
In my program I have a picture "biedkrt". I like to test what x an y values I must use in my program.
In the forums I found the following routine:
Private Sub Biedkrt_MouseHover(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles biedkrt.MouseHover
[CODE]...........
However, this code is not accepted:
Error 1
'X' is not a member of 'System.EventArgs'. C:VBtestMayBridgeMayBridgeForm1.vb
5849 43
MayBridge
The same for Y. I tested when I commented the Label line out, whether this routine is executd when moving the mouse into "biedkrt" which is the case.

I have this code in my system which I use to retrieving images from a database by formatted blob. But some database records don't have pictures ([BLOB - 0 B]). list code for me to place an error picture in picture box1 when a picture is not available.
Dim bytes() as byte
bytes = (objdr("picture"))
Dim memStream as New MemoryStream(bytes)
PictureBox1.image = Drawing.Image.FromStream(memStream)

how could one insert in a form popping up info boxes. I used mousehover event but the only idea was to display a messagebox.What I mean is like the info boxes displayed in visual studio when the mouse pointer is in the area above an object or a function etch. This is a sample code so far:
Imports System.Math
Public Class Form1
Private Sub FillValues(ByVal sender As System.Object, ByVal e As System.EventArgs)

I have a SplitContainer control with DataGridView and WebBrowser controls. I'm trying to call focus to the WebBrowser whenever I hover over it so I can use mouse wheel to scroll. I can do that with the DataGridView since it supports MouseHover, but what can I do with the WebBrowser control to achieve the same thing?

I've got a textbox with a mousehover event and that event will only happen once and then I have to move my mouse out of the text box before it'll happen again. Is there a way to reset the mousehover event 'trigger' so that it happens as many times as I want?

I have a project with Control arrays that include over 200 controls.
I could use Tipster to define a Tool Tip or I could assign a Handler for the MouseHover event & use the handler to provide a help remark.
Would the Tipster approach result in the use of more memory/code than the MouseHover approach to this job?

I have created some labels and i need them to display a popup message when you hover the mouse over them at runtime. I searched for a solution but i only found out how to display popups when hovering over a button and also the code for that was overly complicated.

I am working with a picture box. I have multiple forms and multiple picture boxes. I am trying to go thru and set the default image for all of them and once i got about halfway through I am getting the following error.
System.Windows.Forms.Picturebox has thrown an unhandled Exception in the designer and has been disabled.
Exception
Out Of Memory
I am not sure why this error is happening. I have done some testing. I cannot add a background image to any other picture boxes on any form at this time. I have tried this on multiple computers. Im just not sure what to look at next.

I wrote a 2008express program last month. It worked as planned until 23 Aug when the following message started appearing about 6 seconds after launch, either the exe (which my wife uses) or in debug mode: "Internet Explorer Script Error An error has occurred in the script on this page. line: 42 char: 1 error: object expected [URL] Do you wish to continue running scripts on this page? Yes No"
Internet Explorer is not the default browser - Firefox is. How could IE get into the picture? The message comes up even if the user does nothing. I deleted all commands invoking the browser and all the code relating to accessing the web - still get the message. No line 42 in the entire project refers to accessing IE or the web. If you click Yes or No on the message, everything is OK from then on. What is "this page" the message refers to and how do I get to it to make some change? If I get to "this page", is it possible to make a change? What would make the message come up after over a month of normal use with no changes to the program?

I get "a generic error occurred in GDI+" raised. Googling reveals a few hits for this problem but seemingly mostly related to using databases rather than the file system.
Has anyone come across this? I don't want to paste all my code here in case my nemesis is watching, however basically I'm getting a reference to the PictureBox's Image property and manipulating the pixels using GetPixel and SetPixel, and then setting the picturebox's image property = my modified bitmap.
I understand that the error is generally related to the bitmap not being ready to be saved - is there anything specific I need to do to "close" the bitmap so it can be saved?The strange thing is that I'm sure this was working earlier today and now seems to have arbitrarily stopped working.
