VS 2010 Get Image From Access OLE Object Into PictureBox In VB Code?
May 10, 2012
I am programming with Access 2007 VB.net in Visual Studio 2010.I am trying to have my VB program read the database, extract the .bmp image, and assign it to a PictureBox on the fly (I am actually creating a Group on the fly and filling it with data from the database that are selected by my query. One of the fields is "image". All of my other fields are successfully transferring from the DB to the group box.) My problem is converting the OLE Object to a picture/image that I can assign to the PictureBox.I am using TableAdapters and queries set up in an .xsd.I have a database with an OLE Object field.Here is a code snipit of my database set up:
Dim ta AsNew dsWhiteboardTableAdapters.MonstersTableAdapter
Dim monsterList AsNewdsWhiteboard.MonstersDataTable
Dim monster AsdsWhiteboard.MonstersRow
[code]....
I have tried several ways of getting the image into my picturebox, all lead to errors.
my goal is to copy the content of a picturebox, to a System.Drawing.Bitmap object, called tempBMP. but i didnt even use it i just tried to declare it there's an error: Object reference not set to an instance of an object.
here's my
Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click Dim colors(sizeX - 1, sizeY - 1) As Color
I am in the process of creating a relatively simple "yahtzee" game for a final class project. I have a "Roll the dice" button on my form that when clicked chooses 4 random numbers 1-6. Each number is a seperate "dice", each of the 4 pictureBoxes is meant to represent a seperate dice. A series of If then statements is being used for each picture box so that for example The random number is 1, a image of a dice facing the 1 side is displayed.[code]...
I'm inexperienced with windows forms (vb.net), and I have a rather silly question.I'm opening an old project of someone elses, and there's a PictureBox control on the form. The PictureBox has a photo, and I'm trying to find the location of the photo on the computer but can't find it.In ASPX, I can just look at the code behind and find out where the tags are pointing to (for the photo).The only code that exists for my object, with the image property is this: [code]
i am working a "image processing system" project in vb.net using the ms access2007.i have to browse by clicking a button and open a image to display its name to a text box and that image to picturebox.and after that i want to add,del and extract those images to the access database.i want to use datagridview control also.
how to retrieve image from access database?.. I've just finish retrieving data to the datagrid view. I want to retrieve also the image (also stored in the database as path inside the table where the data stored) in the picturebox. When i clicked the specific data in datagrid view, it will show preferred image to picturebox.
Ok i have a bigger image than the picturebox and when i resize the picturebox half of it gets missed off. How can i get it so the image fits the picturebox exactly??
I get how to stretch an image in the picturebox, that's easy. Now how to make sure it keeps that original ratio, so it's not distorted? Maybe it's as simple as a different setting on the picturebox? Maybe I am mistaken and want to use a different tool?
1. i create a widows form application. 2. i place a picture box in the form. 3. i import a picture. 4. I run the program, (there is no code, simply a picture in a picturebox)
when i do this the image automatically crops itself! it zooms in on a piece of the image i have in the picture box. I have tried different picture types eg JPEG, PNG, BITMAP, GIF etc, same result. I have reinstalled visual basic 2010 Express. Still same problem.
I'm having problems making an image properly "transparent" Dim x As Integer Dim y As Integer Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click [Code] ..... The initial image is Transparent, however, once you create another image very close to it, there is a "box" around it. That "box" is what I am trying to get rid of. I have no clue on how to get rid of it. Yes, I have made the image itself, transparent, as the initial image is transparent. Just any image that makes contact with the other images show the "box".
To use code to select an image for a PictureBox I can do this:PictureBox.Image = My.Resources._1, where 1.png is the name of the image file I want seen in the PictureBoxI want to use a randomly generated integer to select which image is seen in the PictureBox.5 would select 5.png12 would select 12.pngThe .png files are already in the Resources folder.I can generate the random integer and have it in an intVariable but I don't know how to use it to to tell the PictureBox Image property what to do.
I am trying to work out a method to reset the image property of my picturebox on the fly.
I am able to load the original image from a file. But i want to save a clean copy of it before i draw on it. Between drawings i want to be able to reload it.
Here is what i have tried
Dim img as image Using OpenFileDialog1 As New OpenFileDialog With OpenFileDialog1
[Code]....
the code does not seem to work it just freezes. Im not sure exactly whats going on with it.
Is there a way to tell the DISPLAY size of an image in a picture box? If the PictureBox.SizeMode=Zoom, the picture sometimes is not displayed as big as the picture box is, and is sometimes displayed smaller, or larger, than the actual image is. I just want to know what size it is actually displaying as.
My current situation: I have a scrollable picturebox (achieved using panel + picturebox). On top of the image inside the picturebox I've added labels on different locations(the labels are added on run-time using PictureBox1.Controls.Add etc). I want to save the contents as well as the image inside the picturebox.
An OLE Object column contains images but the image type (jpg/gif/tiff) is unknown. These images need to be extracted from the DB and saved to disk. The application is primarily using VB.NET but C# examples are welcome too.
I am trying to write a program which loads a tiff image on picturebox. Then the user clicks somewhere on loaded image to set the starting x,y coordinates and clicks again to set the ending x,y point. Then clicks the run button and the starting and ending x,y points are written on label.
Just to test the program a loaded a tiff image that has a dimension of 75x75 pixels. When I click upperleft and downright corners of the image, the program outputs the coordinates as starting x,y as (103,89) and ending points as (170,157). The program outputs wrong coordinates becayse the image has 75 rows and 75 colums only. To me, it should have outputted starting point as (0,0) and ending points as (75,75).
Public Class Form1 Dim StartX, StartY, EndX, EndY As Int16 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
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'm trying to fill out a webform where the user gets a image in a picturebox and then enters the requested text.But when i submit it to the forum nothing happens This is the code of the html page:
quite new to database queries through VB. I have just created a DB using MS Access and I need to write data to it from my VB Application.Can anyone point me on which objects should I use to execute these write transactions?
I drew an image in a picturebox with the image height as picturebox height and image width as picturebox width. The image is placed somewhere on the center of the picturebox. My intention is to scale the image to fit to the picturebox.
I have a program I'm working on that, for one of the features, allows the user to drag an image from a picturebox, into the main form space, anywhere they want. [code]...
When trying to drag the image from the CurrentTilePicBox, the very moment I move the mouse while dragging the cursor becomes a circle with a cross and won't drag and drop into the new picturebox.
