I am using VB2008 in VS Prof and try to convert at Byte arry stored as a Image format in Sql2000 database.
Code: Using acnLoc As New SqlConnection(CSLoc) acnLoc.Open() Dim G As SqlCommand = New SqlCommand("SELECT [SignatureData] FROM [MyTable] where [OID]=@OID", acnLoc) G.Parameters.Add("@OID", SqlDbType.Int).Value =Cint(bxShipmentno.Text.Trim()) dim P= G.ExecuteScalar() 'returns a system arry
When I try and compile code in vb.net 2008 I get an error that says "value of type 'system.drawing.image' cannot be converted to integer. The error happens at piccolor.image GetDIBits(Form1.PictureBox1.Handle, picColor.Image , _ 0, Form1.PictureBox1.Height, pixels(1, 1, 1), _ bitmap_info, DIB_RGB_COLORS)
Here's the code that explains what piccolor.image is, it's a picturebox on form1 that has an image readpic(Form1.PictureBox1) Public Function readpic(ByVal picColor As PictureBox) GetDIBits(Form1.PictureBox1.Handle, picColor.Image , _ 0, Form1.PictureBox1.Height, pixels(1, 1, 1), _ [Code] .....
And Imports System.Runtime.InteropServices is on the top of the module, if u need more code then let me know. Also I wonder if there is a way to bitblt directly to a pixel array.
I am attempting to make a browser. I have a menu drop-down where the user can choose one of a couple colors. I set up each button, panel, text, etc... as my.settings. I have tried to write the code two different ways, but neither works. How would I fix this?
code:
I keep Getting the Error: Value of type "System.Drawing.Color"cannot be converted to 'String'.
I am making a web browser using geckofx. I have put the favicon in a picture box but I have changed my mind and now I want it as the form's icon. The code for the favicon is:[code...]
The favicon works fine in the picture box but i think it will look better as an icon. If i change the line Me.PictureBox1.Image = favicon to Form1.icon = favicon I get the error Value of type 'System.Drawing.Image' cannot be converted to 'System.Drawing.Icon'. How can I get this to work?

I have a program that creates a Treeview from information procured through an ODBC query and dumped into a dataset. I have three such queries set up via radial buttons as well as a refresh button that triggers whatever radial button is active at the time it's clicked. The purpose of this program is to allow drag-and-drop of selected nodes, ending with a post to the database that officially makes that change of assignment to the new node.
I am currently using Visual Studio 2008 (VB.Net) and SQL Server 2008. I have images saved on the database as image. When I fetch it into my code it is a System.Byte[] and I am unable to cast it as a System.Drawing.Image to save to my DevExpress(v10.2).XtraEditors.ImageEdit.
I', working on a program where there are several projects within a solution. The solution contains a forms application, a couple of class libraries, and a public interface.I'm running into a strange problem where I can access the system.drawing.bitmap namespace from the main form and from one of the class libraries, but when I try to access it from the other class library or the interface, it tells me it is not defined. I've tried importing it, and calling it directly with no luck.
I want to create a list of BrushInfo which has properties of a brush name and its type from System.Drawing.Brushes.[code]The code above will get me the name of the brush (p.Name) but will not get me the type of the brush (i.e. System.Drawing.Brushes.AliceBlue). How do I get the brush type?

If i wanted to crop an image in VB.net, how would I go about doing it? I am trying to let the user drag out the box they want (system.drawing.rectangle), and it will automatically remove the edges surrounding the box.
My first problem is primarily the fact that I cannot make the system.drawing.rectangle visible. It is not displaying at all, I am setting its location and height programmatically, but nothing is showing up. I know there is probably something fairly obvious I am missing...but I cannot seem to find it.
My larger issue, however, lies with the cropping itself. I cannot find any crop methods, at all. Is there a hidden one I am missing? Or must I code it myself? How would I go about doing this? It ought to be able to output to a bitmap image object.
I have a VB.NET Windows Forms app with a logo image on the form as a System.Drawing.Bitmap inside a PictureBox.I used the Visual Studio Designer to add the logo .bmp image so I don't currently have any VB code doing anything with it.I'd like to make the current logo a clickable object/button so when I click on it a file browser dialog opens and I can select a new image to replace the current image.The current image is a local resource and is set in a PictureBox as a System.Drawing.Bitmap.How would I replace that System.Drawing.Bitmap with a file selected from the file browser dialog?
I want to pass an optional parameter to a function of type System.Drawing.Color. The problem I am having is that when I declare the function it says "Constant expression is required" but I have tried variations of the following, including integers, full qualified indentifiers, even old vbWhite constants to no avail.
draw individual pixels, without resorting to drawing a line and setting it's length to 1. Is there an actual ability to draw a pixel that is just 1 pixel big?
I'm having issues with the way I've been reading my image datatype blobs from my SQL database (code below). This code works fine when I access this page directly. The PDF will open and works just fine. However, when I try to use this page to download a file and save it to the file-system programmatically, it fails (500 server error) and I've verified that it's the same URL either way.So, my question is what is the best way to download a file from a database image datatype and save it to disk?PDF.aspx
I have an InvalidCastException Error in my program. The program is that i try to insert an employee record into a database table after getting the details from a form. I've used Money data type is SQL Server for salary and SqlTypes.SqlDecimal data type in employee template class. i've used a stored procedure to pass the values and i add the basic value by passing a parameter by the method

I've used the money datatype itself even in the stored procedure variable.I get the following error.
failed to convert parameter value from sql decimal to decimal Even if i use prm8.Value = Convert.ToDecimal(emp.Bsc)
I get an error Unable to cast object of type 'System.Data.SqlTypes.SqlDecimal' to type 'System.IConvertible'.
