VS 2008 Web Based Images On Hover With A Datagridview?
Dec 8, 2009
I have an application i am working on which gets data and places it into a dataview.
One of the columns contains a url that shows an image of the item being listed, my question is is it possible to have a floating imagebox so that the image is displayed when i mouseover the url? this would be a bit like a preview the images are not large (64x100 say)
My initial thoughts on this would be to use a tooltip but can i use images from a url with a tooltip? if so how, if not how can it be done?

I am starting to develop a card game client for a CCG a friend of mine and I are creating.
I have 2 forms Client.vb and Hand.vb linked with a module.vb
In essence when the app starts up I see the client. I can then click the "Hand" button and the Hand Window is shown as well.
What my goal is is to have it so that when i hover over the card (picturebox) in my hand form that it displays a larger image of that card in the preview box (Another picture box) In Client.vb
I have everything working except when i actually mouse over the image in the hand form it creates an error:
Error:A first chance exception of type 'System.NullReferenceException' occurred in CCG 2.0.exe
The code in the mouse hover event:
Code:
F1.PictureBox2.Image = F2.PictureBox1.Image
Im Almost certain im going about this the wrong way but I cant seem to figure out any other way...
PS.I have attached an image to demonstrate what Im trying to do...

Currently Im doing research on something that are related to graphical password.Can I know is that possible ASP.net(vb) can do such things.when mouse hover over a image, that image id will automatically save in database?Lets say that there are multiples images display in GridView. Only 2 images is the answer. So when user use mouse hover on those images, those images id that mouse hover will saved in database. Then, system will check 2 images id is in the list that mouse hover just now or not.

I am using VS2008. I have a table in which the jpg images are stored. I can retrieve the images from the table and display it in datagridview. But many images are of different sizes. So the cell height of the datagridview changes according to the image size. Is it possible to give a fixed cell size for the image column and also shrink the image to that cell height.

I have a datagridview with several columns, but what I�m trying to do is sum km2 column based on date. I�m using the following
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.CadastroSeqTableAdapter.Fill(Me.Db01DataSet.CadastroSeq)
[Code]....
The query is grouping by DATE (data), this OK, but the km2_FF values not, is not showing anything. To be more clearer, this datagridview has different values of km2_FF for the same date, I want to display the total of km2_FF for each day.

I have a datagridview that's taking a while to load because my table contains almost 5000 records. How can I provide an easy way for clients to filter the grid based on a product name. I was thinking of having labels with each alphabet on my form and when they click a label it filters the bindingsource according to the chosen alphabet. this seems like an awkward solution though.

I am working on Datagridview. My task is adding buttons in the Datagridview table based on the case statements. Like In the Present table i have one column called "CategoryDescription". In this column, values are like 3101,3102, 3103........Here 31 is the common. and like 3201,3202,3203......Here 32 is the common. Like there are so many common values are there. So where ever the common values will come there i have to add one button in the Same column.
So Finally my conclsion is at Satrting 3101 and starting 3201,3301,3401.. i have to add one button control 3101 and add button control on 3201 and add button control on 3301.

My program utilizes various images of different sizes. I want to organize these images so that they all fit into a predetermined space without resizing any of them. They need to be organized in such a way to use as much of the predetermined space as possible. I guess it would be like organizing photos in one of those old photo albums (with the translucent, mildly adhesive, peel-back plastic sheet that held the photos in place) so that you could get as many photos on a page as possible. Or you could think of it sort of like Tetris? Except all the pieces are rectangles.
I assume I would use a recursive function to loop through all the images to find out if they fit or not, then returning the best outcome? I tried searching for code samples but searching for Organizing Images or Organizing Shapes gives less than desirable results.

I'm in the midst of creating the classic "Higher or Lower" game and am trying to learn new things and different techniques. Firstly: I have 3 radio buttons in a group box which have 3 difficulty settings (easy, normal, difficult) and would like it so when one just hovered over a radio button a little caption would pop up saying the maximum score possible. For example, hovering over the "easy" radio button will say "Max Score: 1000".

The app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

I am making futile attempts to get the DataGridView control in a Windows Form to disply several rows of images. The images are all contained on the local disk. The names of the image files (all .JPG or .GIF files) are taken from an XML file. The XML is not the issue, since some of of the images actually appear.
The control has three DataGridViewImageColumn objects. Each column is set up to display a file called Blank.gif which is a transparent GIF containing a single pixel. Later, during the form's Load event, I replace each cell's Value property with the image that the XML file says should be in the column. The XML file contains the name of the file, and I use the System.Drawing.Image.FromFile() method to create the image object from the file name.
The behavior I am experiencing is that that only the very last row of images is properly displayed. The rows above it display the Blank.gif file as if they had never been assigned their intended images. If I change the code so that it will only iterate through three images (one row), all the images show up in the grid. If I then change the code so that six images are processed, only the second row of images is diplayed, and the first row shows only the Blank.gif file's image content. If I change the code to process nine images, the first six show up as blank, and the last three in the final row are properly displayed.
I have lost a considerable amount of my little remaining hair trying to fix this problem to no avail.
The code is as follows:
Imports System.Text
Imports System.Windows.Forms
Imports System.Xml

I have been trying to make a problem, that allows me to open a excel worksheet into the datagridview, and then print the datagridview out. However, the code that I'm using now to import the excel worksheet into the datagridview, doesn't import the images from the excel worksheet.[code]Is it possible to get the correct posttion of each table, and the images, so if i print the datagridview out, it look just like the excel worksheet, but was just edited before printing.

I am trying to load a DataGridView with a XML file. I got that part pretty easily. But I am having an issue with changing a column to an image column and then converting the text string to the image. This is how my xml is laid out.
[Code]...
But I cannot figure out how to change the 2nd column to in image column. I need to change the {3}{G}{G} to images. Each number and letter would be a different image.

i have a datagridview which has a datasource of a SQL database. In this database i have a column which has a boolean value, and in my form, it is used to specify whether a checkbox is ticked or not. What i need my program to do is color the cells of the datagridview based on if the checkbox is ticked or not for the particular rows which have it ticked in the database. Here is what i have, but it doesnt work:
Code:
Dim count As Integer = 0
While DataGridView1.CurrentCell.RowIndex <= DataGridView1.RowCount
If CellIDCheckBox1.Checked Then
[code]....
what im trying to do here is loop through the datagridview and see if the checkbox is ticked or not and coloring it based on that.i have also been messing around with some LINQ code, but that doesnt seem to work either..
