Make Several PictureBox Images Randomly Visible = False And Then Back To Visible = True Giving The Appearance Of Flashing Or Blinking Images?

Jun 28, 2010

I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree.  I can make the lights randomly flash using a randomGenerator and a Select case statement.  However, the code is very long.  There are 67 lights on this tree and the code is 71 pages long.  There has to be an easier way to do this.   So far I have tried the following with two images of lights just to see if it would work and it does not work:

Dim picLight(2) As
Boolean
For intX

IsDate Function Giving Back True Value When Expecting False?

Jun 22, 2010

I am using MS Visual Studio 2205 Version 8.0.50727.42 and MS.Net Framework Version 2.0.50727 SP2 I created a form that requires the user to enter a date into the textbox.I then use the IsDate function to check if the entry is a valid date.  IF Not IsDate(fieldname) then send message back to user on form, otherwise continue.If something like this is enterred - 06/090/10 - It passes the IsDate question and of course fails at the database level when inserting to a datetime field.  Although there is a three character day, it still passes.

Panel's Visible Property Won't Change From 'False' To 'True'

Mar 25, 2012

I am stumped on this one. I have a panel (pnlKeyPad) that won't change the visible property when I try to set it to True. But when I try to set the Dock Property to DockStyle.Fill it succeeds. I have tried them in different orders, setting the parent property to the splitpanel and nothing seems to fix it. The panel is on a splitpanel that is visible. The panel is set to visible = false by default.

Any ideas of why this panel won't switch to visible when I specifically set it to visible?[code]...

Turn A Control's Visible Property To True Or False?

Aug 11, 2011

I know how to turn a control's visible property to true or false, the only thing I don't know is: If I have, for instance, 40 group boxes in which only one is visible, when I click on a button, the first group box visible = false and the second group box visible = true, and when I click on it again, the second group box visible = false and the third group box visible = true, and so on I don't want to write the codes for every controls, since it will be quite time consuming, I want to use fewer codes to achieve this objective,

Make PictureBox Visible In Program?

Jun 25, 2009

I have written a VB2008 program in which I want to put graphics output in a PictureBox but keep the PictureBox hidden until a "Show Graphics" button is pressed at runtime. I have done this by setting the PictureBox's Visble property to False at design time and then adding a line in the Button Click code (before the main graphics code) to make .visible = true. Now when I press the button, the picture box becomes visible but stays blank. I have to press the Button a second time to get the graphics to show. It doesn't matter where in the Button code I place the PictureBox1.visible = true line, the result is the sdame. WHY ? Other VB Controls, eg RichTextBox will stand being made visible and then display output with only one click of the button, why is PictureBox different ?

DataGridView (slow Processing Of 'visible = False')?

Jun 19, 2010

A DataGridView in my VB.NET 2008 program contains over 15,000 rows.   I loop through the rows, totalling groups of rows and appending 'total rows' and one 'Final total row' to the DataGridView.   That works fine.   I want to initially hide all rows except for the total rows, giving the user the option to show all 'detail' rows.   If i place the statement  << dgvTitleCounts.Rows(intRow).Visible = False >> in the loop, execution time increases by three minutes and that is unacceptable.

I see two options:   (1) find a faster way of making all rows invisible; and (2) place the total rows in a separate DataSet and bound DataGridView.

I got a couple of issues with my windows application VB.Net. I seem to cannot set the form to be invisible before it shows up for a second, there is no option in the properties of a form and also if I set the form to visible = false before the form is loaded it doesn't work.

So this does not work:

Browser.Visible = False
Browser.Show()

and this does work but the form shows up for a second which I am still not very happy with

VS 2010 :: Make An Application To Save Images [or Download Images] To Local Hard Disk

Aug 12, 2010

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?

VS 2008 Button Set To Visible = False Causes Form To Not Open Properly

Under the same circumstances if the Button is set to visiblbe = true the form does open properly or if the line of code at a certain place where it is set to either visible = true or visible = false is commented out or not there then the form opens properly. If any one of the 5 phases on my form are turned on then the problem doesn't ever occur but if none of the phases are on then the problem does occur. I just found a fix for the situation but I still am not clear about what exactly is going on.

Jumping Between Forms - Making A Form Visible And Not Visible

Jul 17, 2009

I'm having an odd problem when making a form visible and not visible and it not continuing to function. Here is what I have happening. I have a main form (frmMain) that is an MDIParent. On this form I have a menu to open a second form (frmCalculate) and populate a listview from Items in the database.

As I click or select items in the listview on frmCalculate the tag is read and data is pulled based on the id stored in that tag and fills in various fields on the form. This works great. However, I also have a context menu attached to the listview that allows me to perform a "what if" scenerio on the items I am calculating. When I select this menu, I hide the frmCalculate and open the frmWhatIf form where I can mess around with values on the item I had hilighted in the listview on frmCalculate. Nothing is pulled from or written back to the database here, all the information is filled in from fields on frmCalculate. It just allows me to look at rising costs and how they will affect my margins.... anyway.

If I then close frmWhatIf, it brings my frmCalculate back by setting its visible propery to true (never closed frmCalculate, just hid it). At this point if I click an item in the listview I get an exception for a null reference. IF however I never hide frmCalculate, I can open and close frmWhatIF without ever having an issue. Why do I lose the functionality to select items just by hiding and unhiding the form? As a test I added two menus to the toolbar on frmMain one called hide and one called show. I then opened frmCalculate with original menu item to populate the listview and selected a few items to test that it was working and then using the hide menu I made the form invisible and the show button to bring it back. This yielded the same exception so without even opening frmWhatIf the problem still occurs.

VS 2008 : Stray Graphics Path Image Generated When Label Is Set To Visible = False?

Oct 11, 2009

I have a graphics application that uses graphics paths. Code seen below. You can use keyboard characters to display information. When a label is set to visible = false after being turned on for a number of seconds a stray image is generated. The stray images are also sometimes generated when the label is first made visible.

' points p10b, p2b etc are defined elsewhere
Dim GrpPoints As PointF() = {p10b, p2b, p3b, p11b, p5b, p6b, p12b}
GrPath = New GraphicsPath ' 7 path points
GrPath.AddBeziers(GrpPoints)

[code]....

I tried stopping the code from running when the label is set to visible = false but the stray image is still generated but just later. If you want more information let me know.The white arrows points to the stray image that is created just after a label that displayed information was set to visible = false

Visible Surface Of Picturebox Is Too Small?

Jun 27, 2009

I'm drawing lines directly on a PictureBox. My problem is that the visible surface of the PictureBox is smaller than expected, considering the Height and a Width properties.For example, there is a PictureBox with Height = 200 and Width = 400 points.When I draw a point with coordinates of (0,0) it is clearly visible in the topleft corner. But when I draw a point with coordinates of (399,199), it's not visible. Actually, the bottommost and rightmost point in the Picturebox seems to have the coordinates of (397,197).

What's the reason behind this? Is the PictureBox always two points smaller, or is it size-dependent? Or a wrong setting?
