I have a database (mysql) to which I connect, I have a column in the database (the images) that I view as a grid that is in the datagridview autoimplementa. BUT THE IMAGES ARE STORED AS A URL.
View 1 RepliesHow can i display more then on image in a datagridview column? I already have the column as an image column.I am just having trouble showing more than one image. And searching has come up with nothing besides how to display one image.

View 5 RepliesI am making a program that takes pictures of the webbrowser control on a set timer and save them in a picturebox.. I then use backgroundworkers to check the images against others stored in the program. My issue is, the backgroundworkers do not properly check the images against the ones I have stored in the program.Could this be because the images and picturebox are stored on the main thread, and no in a background worker?In other words, I am taking picture from my webbrowser and putting them in my picturebox. Then, I am comparing them with images already in the images. The only problem is, the workers are unable to properly compare the images.

View 2 RepliesSo I have an application that saves and retrieves images from an Access database. The images are displayed in a picturebox but I'm having a bad time figuring out how can I move to the next/previous record/image in the database, so the user can view them and delete it if he wants to...
Here is a screen of my form so you can better understand what I'm trying to do:
And here is the

Save and delete functions work fine, I just need to know how to do the Next and Previous buttons... This should be easy to do, but I'm still a beginner to VB
Biggest problem is that this is a part of a school work which I must deliver tomorrow.
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?

View 1 RepliesI was just handed a VB.NET prototyping effort, and I'm not very experienced with VB.NET.I had to create a stored procedure which returns a self-referential table in order. Once, I completed that I wanted to get a DataGridView to show the results.
Previously, my team has been doing a lot of this via the GUI designer of VB.NET so I don't have a ton of code to describe, unfortunately.I was trying to follow their pattern which I will briefly describe here:
I have a DataGridView whose DataSource property points to a BindingSource. The BindingSource points to a DataSet. The editor for that DataSet calls a TableAdapter which gets the data from the stored procedure.
I previewed the data for the TableAdapter. The data is there. On frmMain's load the TableAdapter's Fill command is run. Not seeing anything. And my hunch is that this is way too complex a process to be correct. Or maybe not. I did a lot of Google searches before I decided to bother you fine folks.
Using SQL Server 2008 I created a Stored Procedure called MyStoreProc and it runs fine from the Management Tools.
In VB.Net 2008 I created a new dataset and a new TableAdaptor. In this table adapter I created a new Query called FillByGrid and selected the Stored Procedure. Previewed data and it previewed correctly.
On a form I created DataGridView and selected the Table Adapter from the dataset.
I ran the app and no data is shown. Visual Studio autocreated the code below and I changed it to select the the Query I just created:
Me.MyTableAdapter.FillByGrid(Me.MyDataset.MyTableAdaptor)
No data is shown on the grid so I tried the manual approach:
' Create the dataset
Dim da As New SqlDataAdapter, ds As New DataSet
Dim conn As New SqlConnection
[Code]....
Still no data shown. However stepping through the I can see that the connection is open, and "da.Fill(ds, "tbl1")" takes a little bit of time as it is running the Stored Procedure and ds table has the correct number of rows and columns. Its just not being shown on the datagrid.
Creating another table adapter in the dataset and returning data from a database table using a standard select * from table command display in the datagridview fine.
I have a problem in populating datagridview using storedprocedure i tried but i cant get it.[code]...
View 2 RepliesI have a number of tabpages that each contain a datagridview control only. Based on the results of a SQL statement I then loop through each tabpage and set its name. The reason for this is that at runtime (and depending on the results of the SQL statement), the contents of each tab page will change - henceI loop through the tabpages and set the name/ text (to reflect what will later be shown in the DataGridView)
The datagridview control on each tab has the default name e.g. DataGridView1, DataGridView2, DataGridView3 so it's easy for me to loop through them e.g.:
for i as integer = 1 to 3
[code].....
I have a form that I'm running a stored procedure in and I'd like to pass the results to a datagridview and then offer the user the ability to export those results to a flat text file.
View 1 RepliesI've noticed that I can use LINQ to call a SQL Stored Procedure and use those results in a datagridview and have sorting by column automatically included. However, if the LINQ call is done on a web service, it seems like I have to return the results as an array which, when it gets back to the client, doesn't have the interface needed by the datagridview control to do it's sorting. I haven't been able to find an easy way to get the sorting ability back.
I've tried to serialize the result on the web service but the returned type can't be serialized. I tried putting the data context in a common DLL so I could use the Attach functionality but that doesn't exist for stored procedures. I suppose I could make a table in the data context just for this purpose but that will be a pain to maintain. Would I just be better off skipping LINQ and using an old fashioned typed dataset for this?
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
[Code]....
i manage to display the table but my imgcol that contain image only display a box of x.. in my database column for the image, i put this.

View 1 RepliesI have an app written in vb2005 that allows users to search a sql database for a store name. Once a store is selected, it then presents the user with 12 different tabs, each with a DataGridView showing various bits of info about the store. It's a large and convoluted database, so I'm using stored proceedures to pull the data for each tab. Here's a sample of one of the subs that populates the tabs.[code...]
Now, this works just fine to populate the grids on the tabs, and the same code is copied into each of the subs that fill the grids (changing the stored proc, parameter and grid names, of course). The problem I'm having is how to move changes made to the data in the grid back into the database.
I have stored procs that do this (and the procs do work), I just can't seem to figure out how to trigger the stored proc when the user makes a change.
If it matters, there is only a grid on each tab, I did not use a binding source as I am trying to keep an abstraction layer between the data and the app. I did create a dataset, which is how I gain access to the stored procs, but I left the grids unbound and (as seen in my code) bind them at run time.
Using VB2008 How can we fill the datagrid with information from a stored procedure and a sp variable.We have a dataset named: DBnamesDataSet, a source: ShownameBindingSource and a adapter: Show_nameTableAdapter.
Stored procedure:
alter PROCEDURE [dbo].[show_name]
@name varchar(50)

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.

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.

View 12 RepliesI 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?
