I have this code in my system which I use to retrieving images from a database by formatted blob. But some database records don't have pictures ([BLOB - 0 B]). list code for me to place an error picture in picture box1 when a picture is not available.
Dim bytes() as byte bytes = (objdr("picture")) Dim memStream as New MemoryStream(bytes) PictureBox1.image = Drawing.Image.FromStream(memStream)
How can I associate an icon path with a picturebox by pasting the path into a textbox and then pressing a button? I've been trying different things with the system.drawing.bitmap and system.drawing.icon but they don't seem to work OR I'm using them the wrong way.
The icon I'm trying to extract and put into the picturebox: C:WindowsSystem32shell32.dll,3 (the 3rd icon in shell32.dll)
I go and find the picture on my computer right click on it and find its location and copy and paste it into the .imagelocation adding a and the picture name and every time it says picture cannot be found? I have tried loading it from C: or from my jump drive E:
I am working on a Vb6 to VB.net migration application.I am not able to proceed in one place.I have a Resources.Resx file in my application in which some Icons are stored like "icoUS","icoCA" etc. And there is a combo box where some country names are listed.On selection of this combo box, the corresponding countrie's flag image should be dsiplayed on a picture box.[code]...
I'm using a listview in my application.(view=details) when user try to sort the listview by clicking the column header i use the imageindex property to set an icon for that column header, but I don't know how to remove that icon from that column header when user clicks another column header. How should I remove the icon(picture) from the previous column header?
I wrote a 2008express program last month. It worked as planned until 23 Aug when the following message started appearing about 6 seconds after launch, either the exe (which my wife uses) or in debug mode: "Internet Explorer Script Error An error has occurred in the script on this page. line: 42 char: 1 error: object expected [URL] Do you wish to continue running scripts on this page? Yes No"
Internet Explorer is not the default browser - Firefox is. How could IE get into the picture? The message comes up even if the user does nothing. I deleted all commands invoking the browser and all the code relating to accessing the web - still get the message. No line 42 in the entire project refers to accessing IE or the web. If you click Yes or No on the message, everything is OK from then on. What is "this page" the message refers to and how do I get to it to make some change? If I get to "this page", is it possible to make a change? What would make the message come up after over a month of normal use with no changes to the program?
i want to implement undo/redo function in icon editor, im try to use arraylist or Stack to hold current icon or picturebox image when mouse up and left mouse is not press. i dont know exact place to put the Stack for push.
I've written a simple application to encrypt an image (jpeg file) based on a password as a challenge to a mate of mine who reckons he's an ace hacker.I can encrypt the image no problem but when I try to save it using
I get "a generic error occurred in GDI+" raised. Googling reveals a few hits for this problem but seemingly mostly related to using databases rather than the file system.
Has anyone come across this? I don't want to paste all my code here in case my nemesis is watching, however basically I'm getting a reference to the PictureBox's Image property and manipulating the pixels using GetPixel and SetPixel, and then setting the picturebox's image property = my modified bitmap.
I understand that the error is generally related to the bitmap not being ready to be saved - is there anything specific I need to do to "close" the bitmap so it can be saved?The strange thing is that I'm sure this was working earlier today and now seems to have arbitrarily stopped working.
I have VS 2008 and use VB, not C#/C++ or whatever else. I'm trying to make a battleship game, and I've decided to use the only method I can think of to control the grid. A 2D boolean array for position marking. I have the array set up, and the grid set up in the design form, but I can't figure out with all my research how to link them together. I'm writing this program to shake off the rust before school starts again, and for fun. I took VB in school last year, a half year class, so I have a foundation, now I'm self-educating myself above and beyond the class. I've searched for a way to use a picture box array to use the coordinates of the ship to .Visible=True the picture boxes. I've been working on this for 2 days straight with no results. I just need a little nudge in the right direction. The exception I've been getting with my latest concoction of code is NullReferenceException was Unhandled. I think its referring to the fact that I have no idea how to link the picture boxes into the array. Here's my code, and I'll comment where the exception is thrown:
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click 'label for GoTo statements is Tryline:
I need to display a arrow picture over another picture. But i cant able to make arrow picture transparent other than the arrow. Always it is in rectangle format(Picture box). I tried the picture box color to transparent, But that doesn't worked. A separate user control for displaying transparent image will be appreciated.
we are having a problem in drag and drop some pictures, so here it is.have pictures put in the tool strip about 10 pictures, then we are to drag and drop it in our workspace made up of a one picture box. when we drag a picture on it, yes it appears, but when we drag another picture, the first picture dropped in the work space is overwritten by the second picture, meaning it was gone. how can we drag multiple picture in that picture box?and also. can we place the picture anywhere in the picture box?i mean the default i think is on the upper left corner ...can the picture be placed anywhere?
My project have a Picture box control for loading pictures but it's worked fine my problem is... some vertical Jpg picture was shown Horizontally in windows explorer and also my picutre box control at that same that file was opened with vertically in editors like photoshop. but i need not picture rotate codes i want to Vertical picture was shown as vertically into my picture box control is't possible,
I have been looking on youtube and google for this, I cant find a tutorial for this. What I want to do is set up a progress bar and when the value of the progress bar = 20 I want the image in the picture box to change to another picture. I tried this, thinking it might work. But it doesn't
If ProgressBar1.Value = 25 Then PictureBox1.Image = HabboEz.My.Resources.Resources.hat2.
I know how to find the mouse coordinates of different controls and such. What I need is slightly unique.I'm needing to find the coordinates of a picture within a picture. So if I had a picture of a black box with a red x in it, I would need to find the red x inside of it.I already have the bitmaps of the images, so I only need to know how to find the coordinates of where the images lie inside one another.
i have this problem i would want to solve urgently...when i import a picture into my picture box in vb.net using this code
The img_large_watermarked.jpg image shows up on successful submission...i also want to change that too..cos as soon as i moved systems it could not detect C:Documents and SettingsstanleyMy DocumentsMy Picturesimg_large_watermarked.jpg and that caused errors.
My plan is to use a database to hold her recipes and create a user interface with search controls and different stuff, this way she will be able to add new recipe's and the program will have a much more modern feel to it.
My question is, I have added a picture box control to the new recipe form and when I click on the picture box I want the program to load "my pictures" and let me select a picture to load into the picture box, like you can on ebay when you are selling stuff, you can select your picture and it loads into the picture box.
As far as starting this off, I can add a double click event on the picture box control, this will trigger whatever code I need to use to load the open file dialog.
Can I use simaler code that I used for a text editor program I wrote for opening saved documents?
I'm a programming enthusiast, and recently I am making a program that communicates with a webcam and captures an image. I copied the API call for avicap32.dll from some website and the program works just fine.
I have some operations of Picture Boxes etc being performed. After the user finishes with the formatting, I want to give the user an option to print the work.But its the work is not done on the Rich Text Box but on picture boxes. I am not even sure, how many of the picture boxes would be there after the user finishes the job, since I have provided option for dynamically creating picture boxes as well.
I have a few problems i need to solve. Firstly, I am looking for a piece of code i can use to display a picture from a bank of pictures. It will work on the basis of generating a random number and loading a picture that corresponds to that number.
i.e. Dim RandNumber As Integer Dim RandClass As New Random RandNumber = RandClass.next(1, 10) If RandNumber = 1 Then Picturebox1.image = picture1
Secondly, can I then use subsequent picture boxes to display pictures from the same bank of images, without displaying the same image? Finally, I then need to be able to click the picture or a button beneath the picture to select it as an answer to a question and then the whole process starts again.
