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

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.

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]...

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,

I have a document management system which creates a report showing people who own which document. There are times where people have 0 documents and in that case I would like the repeater table for that person to not be visible. I have looked around for a while and have not had much luck, I have repeaters nested inside repeaters but if the first repeater is not visible the rest should follow.

I'm working on creating a very simple dice game for class (not for gambling purposes). The users has already entered their total amount of money, and are are able to wager for every round. We were supplied with 6 different picture files to represent the 6 sides of the dice. It will be located in the C:\Temp folder, and after the user clicks a play button, the form (frmDice) will appear, which has two pictureboxes(pbDice1 & pbDice2) located on it.

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 ?

The idea is to scan a folder of images and then let the user navigate back and forth through the images using a couple of buttons.The problem is, I can only get it to return a single image, and not the whole lot. It's looks to me as though the images are getting assigned to the same index in the array. [code]

In my space invaders game, you press start, which creates 15 pictureboxes. When I hit the spacebar, a bullet moves to the top of the screen. What code would allow me to make a picturebox invisible that isn't named yet?

I am trying to make a customer class that will simply make a bunch of controls (hotspots) Visible value = False.
For instance: WinStartSpot.visible = False
Thing is I have roughly 60 "spots" that need to be turned on and off as the user clicks through the program (its a very simple OS simulator) I tried to make a class using boolean return but that failed miserably. how to code a class like that?

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 have a couple of textboxes whose databinding's text is set and also readonly is true and visible is false. but when I try to read their values they are all null unless I turn their visibilty to true. The same method is also needed to add a new row to the table (when using bindingsource1.addnew()).

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
Browser.Show()
Browser.Visible = False

When setting a textbox "Visible" property to False is there any reason why I should also set the "Enabled" property to false.

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?
