View 2 RepliesI am "weeks new" to visual basic 2008 but I was hoping that someone might tell me how I can open an image in whatever type of "visible" graphics window (always positioned at: x=0 y=0); move to some "definable position" of interest x=(n) y=(n); change the brightness of that "individual pixel" by some "definable means of measure" from its original state; and save the new image as a separate image file?
View 4 RepliesHow do you change the cursor image to an image from the project resources?
The methods I have found either don't work or only change the image within the form, and reverts back to default when the mouse leaves the window.
means the images that will display in the picturebox is based on the value shown on the textbox (ProjID)..
Please see code below..

View 2 RepliesI'm writing an application for a device running Windows XP. There are 2 versions of the device and each version has its own API to communicate with the device's software. The application I'm writing needs to pull the same data from the API. My question is how to write a application that will detect at runtime which version of the device it is on and use the appropriate API.
I've created an interface containing all of the common methods and also classes for each device that implement the interface. Now I need to know how to activate the correct one at runtime.
Public Interface IAPI
Sub InitializeMachine()
Function GetActiveProgram() As String

I'm writing a Windows form application. I created a SQL database called myDB.mdf. The database/form connection was created using the wizard provided by VS2008.

View 5 RepliesI have multiple urls to the same webservice, each with it's own "token". I need to switch from one url to another during runtime. I have planned to do this by storing my URLs inside a XML-file, and then read it, copy innertext of an element and overwrite the WS url in my app.config. My app reads and write to xml just fine, it is when I actually use a method from the webserivice proplems start to appear.

I am creating a program that will be sold as a subscription. I am trying to decide how to prevent users from passing the program to others without purchasing it. I was thinking that on the very first run, the program could pull the MAC address from the computer it is run on, and create a constant at run time. This constant is then hard wired into the program and is used for comparison every time the program is run thereafter. If the MAC address do not match, it is on a different computer.
How do I recompile my .exe to include a globally declared constant used for comparison? And how do I use this variable throughout my program?Or is there a simpler way to create my program to require Key Codes for renewal once per year?
I did something that when I now load my program(VB 2008), my controls; combo boxes, buttons, progress bar, etc. look like they are from VB 2005 or like VBA buttons, not the rounded edge buttons of 2008.
They look like vb 2008 controls while I am in design view, but then they change their style when I run the program..

View 1 RepliesI would like to add an image to a crystal report at runtime.
I am currently doing this using a second data table containing only a byte field and then a blob field on the report. However this feels like a hack and if there is no data in the first primary table then for some reason the image does not show.
Is it possible to add an image with code or another method?
I'm using crystal reports for visual studio 2010. Winforms project. Either C# or VB.
i have a program i've made a while, and one of the users wants to be able to load his own images to the background instead of the plain grey that is there now. i've searched and searched, and basically can get this working
BackgroundImage = Image.FromFile("C:UsersMeFileName.png")
i just slapped that onto a button just to get it to work as i was experimenting. but that only works for a file of that name, on my computer, in that folder. what i'm looking to do is get it so a user can browse his own directories for images and upload them as the background on the form. and be able to save the settings as well. but so far i have only seen different ways to load preset images that you can load. if it's even possible? i'd assume that you'd use the openfiledialog command, but i'm not that well versed in vb as of yet.
I'm using Visual Studio just to create GUIs for a project. There is no code, only the designs.
I need to convert these forms into images that I can paste into the report.
Is this possible? I dont want to include a folder of all the images.I want to be able to take an image from the resource and export it to a file.
View 3 RepliesI'm developing a standalone application. The purpose of it is to have no installation necessary. I'm trying to keep it as small as possible, and everything contained in the actual program, so that the user can let it sit right on their desktop. I wanted to make it possible to generate an image, preferably something transparent (.png, .gif) of a certain dimension, and export it to a certain folder. I've explored Bitmap library, but I've yet to come up with a successful solution. I'd be very obliged if someone could point me in the correct direction. Here's my current code:
Dim myPNG = New System.Drawing.Bitmap(fileName:="logo.png")
myPNG.SetResolution(xDpi:=100, yDpi:=20)
myPNG.MakeTransparent() 'creates transparency
myPNG.Save("C:logo.png")
