I want to convert an image to a string, then put it into 1 cell in a datagridview as a string. I've read around on the forums and I saw some people say to use StreamReader, others say BinaryReader. Well Imma try both and see how it comes out. But I'm kinda stump. I'm trying StreamReader first, and I don't know how I should even do this. This is what I've got:
Dim ofd As OpenFileDialog = OpenFileDialog1
ofd.FileName = ""
ofd.Multiselect = False
[Code]....
In my do loop, should I put it into a temp text file and then read that textfile into the datagridview? If I did that, I think it would take up some time.

I am trying to load a GIF file by its string name from my.resources as what GIF to show is chosen at random and based off that random number we get a valid string name. The names come out proper because I used the Msgbox trick
Here is my faulty coding
Public Function PrintCardName(ByVal Suit As String, ByVal Hand As String, ByRef ImgBoxUpdate As System.Windows.Forms.PictureBox)
'Working code omitted to save reading time
ImgBoxUpdate.Image = My.Resources.ResourceManager.GetObject(Card_File_N ame)
End Function
And Card_File_Name is a predefined string, and no there is no space after the letter N in card_file_name it just appears that way because its italicized
The issue is that the Imagebox that is referanced to IMGBOXUPDATE goes blank after this function.

What is the best way to create a non editable image from a text string? Currently I am saving a number of strings to .csv files. Are there any options that do not involve buying additional products? I am using VB.net 2005.

I'm real new to VB and thought I'd try something "simple". I have a form with a button, two pictureboxes and textboxes. When the button is clicked, I am generating two random numbers (1-6) and then want to select a corresponding picure of a dice from the Resource folder (named Dice1-6.jpg) for each of the pictureboxes. The textboxes display the numeric version of the "dice" rolls.[code]...

In my windows form I have an empty datagridview that contains strings loaded from a csvfile. The datagridview has no initial column collection. There are four columns in the csv file. In the csv file, columns 1 and 2 have values of true orfalse. So far I am able to load the text perfectly.
What I want to do is change the strings "true" or "false" into an image in my resources (a pretty green checkmark and a red x).
I would like to leave the csv file text as it is, and then change the columns dynamically.
Then, when I save the information back to the csv file, the images must be converted to text strings to accomodate the csv.

I'm sure there are similar threads, but I've search and tried most things and still can't find something that works.
I am testing a small project, in the attempt to find the solution for a much bigger application. So, here's the deal. I'm using VB 2005 and MSSQL 2005 (both are Express editions). I've stored the names to some images in the database.
When I use PictureBox1.image = My.Resources.<filename>
and build the application, it works and properly displays the image. Now, what I'm really trying to do is extract an image names from the database and assign it to a variable, this is what I have.
Dim EqTest As New Test1DataSet.EqTestDataTable
Dim EqTestAdapter As New Test1DataSetTableAdapters.EqTestTableAdapter
EqTestAdapter.Fill(EqTest)
[Code]....
I've used the messagebox for testing so that I can see what the value of "Trythis" is, and the string is "My.Resources.<filename>", which is the correct string, but I can't use that string in the picturebox to display the image, because I get an error "Value of Type String can not be converted to System.Drawing.Image".

I have this as code to run the program
Process.Start(ListBox1.SelectedItem.ToString.Split(New String() {" "},
StringSplitOptions.None)(1))
Which used to work but then I added a "Preview image" function like this :
(ListBox1.SelectedItem.ToString.Split(New String() {" Image:"}, StringSplitOptions.None)(1))
I now discovered that the first code is useless, because it selects everything after " " to run, including the "Image:"
This is how a listbox item is stored:
Tomb Raider Level Editor - Original C:Program FilesTomb Raider - Level Editor omb4.exe Image:C:Program FilesTomb Raider - Level Editorload.bmp
As you can see it'll use this
C:Program FilesTomb Raider - Level Editor
omb4.exe Image:C:Program FilesTomb Raider - Level Editorload.bmp
to run
Is there any way I can make it choose the path from " " and when it finds "image:" it stops?

You pull the value out of the Request object

How do I set button1.image to the image resource named in a string?
if my_string = "image1" then
button1.image = my.resources.image1
else if my_string = "image2" then
button1.image = "image2"
...
else if my_string = "image30" then
button1.image = "image30"
end if
Is there an easier way to do this?

I assume that this will be an easy one for you guys. I have never dabbled with drawing in VB.NET. I have searched the forum and Google already, but have turned up nothing to help me. Here is my problem. I have an image that is in an image box. I would like to draw a string of text on it, centered vertically and horizontally. Here is what I am using to draw the text.

I'm trying to make a program for a school assessment in VB express 2010 using databases. The program essentially has a panel for uploading an image with a name string and an author string, which it then stores in a database. You can then search the database using the name or author string and find pictures that fit the criteria.

I have a string which consists of the raw HTML of a webpage. I would like to search for the first use of /imgres?imgurl= within the string and display the url of an image which follows exactly after it in a text box. Below is an example of part of the string: [URL]..In this case it would find /imgres?imgurl= then it would display [URL]...

What I have done is named a bunch of picture boxes "Q," "W," "E," etc. (the whole alphabet) and named picture that correspond to these picture boxes ("Q.png," "W.png," and so on) and added them to my resources.
For example, the following code would give the picture box named "Q" it's corresponding image "Q.png":
vb
Q.BackgroundImage = My.Resources.Q
Of course, it's kind of a pain in the backside to copy and paste this code and change all the Q's to W's and so on, so I was hoping to create a function to do the job for me:
vb
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
'So that I can run the letter as a string through the function,
[Code].....
Hopefully I've provided enough detail so that it is obvious what I'm trying to do.
Obviously, the code I tried above (the second block) doesn't work - it gives a syntax error. I need to change/write to make this function functional.

I am currently making a server monitoring application that pings the server to check its uplink, so far it creates all the picture boxes and labels for each server, and then pings the server, although I have a picture that I want to change dependant on the result.
Below is the code I am currently using, the problem occurs with the objectname variable which allows dynamic coding, where i get a error, saying that "Public member 'image' on type 'String' not found".
Private Sub Ping()
Dim i As Integer
Dim objectName As System.Object
For i = 1 To count - 1

I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.
