so my application (Visual Basic 2010) is making use of Image Magick, via the COM object. If the COM is not installed then my application crashes (not surprising). How can I detect if the COM has been installed, so abort and tell the user to install it?

View 6 RepliesI am creating a project with VB2008 Express Edition. The end result will be a CD containing tech manuals in pdf format which will be accessed via various buttons on a form. I am going to include Acrobat Reader Redisributable on the CD which the user can install by pressing a button on the form if required. What I want to do is this:- When the user inserts the CD into the PC, the form will load.When the form loads, I want to search the users PC to determine if Acrobat Reader is installed.If the Acrobat Reader program is not found on the system, then display a MessageBox to inform the user to install the reader from the CD.Would this involve searching the users registry? I would need to insert in my Form1_Load sectionTarget systems would be Windows XP/ Vista with programs on the C: drive as default.
View 4 RepliesI'm working on a project that requires that I programmatically examine the ServiceAccount of all services installed on a machine (regardless of status) to determine Logon Type which will be used as an indicator of which passwords need to be changed on a machine for maintaining security.
If possible I would like to keep the entire project in VB.Net and Ive been looking through the API to find namespaces that contain classes to allow me to do this. Ive come across System.ServiceProcess which does allow me to get quite a bit of information about services installed, but I cant seem to find a way to get the Logon Type (I would guess that it would be returned as a System.ServiceProcess.ServiceAccount object).Ive also tried System.Management using ManagementObjectSearcher and ManagementObject, but Im not sure if theres a way to get that information with a WQL statement (I know next to nothing about WQL, unfortunately).
I have some jpeg images that are added to my application. The Copy To Output Directory property is set to Copy Always. Running from Visual Studio the images are accessed and if I install the application to a drive on my computer directly the images are accessed but if I publish my application to my web site and install via the publish.htm page then the images are never accessed regardless of what I have the Build Action set to.
If the Build Action is set to Content then it won't even install because I get an error that says the computed hash for the images doesn't match the manifest. I've tried all the different Build Action options without success. For Build Action = None, Compile and Embedded Resource I don't get the error I do for Content but the jpeg images aren't accessed.

I am trying to detemine whether an image is currently displayed on the screen or not, even if only in a given location on the screen since I will know the exact pixels it will display it & everything but I am having a hard time trying to determine whether an certain image is there or not.
View 1 RepliesI have an image resembling a chessboard inside a picturebox displayed on the screen at runtime. I am using Visual Basic in Visual Studio 2008. I need to determine when a user clicks on a particular part of the image. I am able to do this without a problem when debugging on my computer, where I can experiment with trial-and-error clicking to get the screen coordinates of the portion of the image of interest. Everything changes, however, when the program is run on a screen with a different resolution and coordinates.
I can easily get the coordinates for the picturebox that contains the image using PointToScreen. However, there seems to be no such property for the image within the picturebox, which is what I need.
Is this possible ? Im creating a desktop wallpaper changer using a timer to set a delay between images. the images im my directory folder is numbered from 1-15. If you look at the pic below theres an option to select how many images the user wants to display on the slideshow, if a user selects up to 15 thats fine. But what can i do if the user enters a number that exceeds the number of images in the directory.
View 3 RepliesI'm attempting to write a solution so that my user's can "watermark" their Images with their Company Logo. I've got the actual watermarking part done and working so now I'm creating the "upload logo" feature so that they can provide me with the Logo they wish to appear watermarked onto their Images.I'm using VB.NET and this will probably end up in a Web Service that accepts the Logo JPG file, and returns the "altered" Logo. What I need to happen in this Web Service is:
1) Gray-scale the image. Which I have working as well, thanks to this article.
2) Make the background transparent (so the logo looks clean when watermarked onto an image). This is where I'm stuck.
I think for the most part, any logos that are uploaded will have a generic white background but I can't assume that. Is there a way to somehow detect the background of an image or the background colors, so that I may make those colors transparent?So basically what I need is just a way to determine the background on an Image or even just the background colors so that I may make them transparent.
I need to export Chart(image) and grid (tabular) row data into excel file. I can not use automation because Office tools are not installed in my server. I've found a bunch of free/proprietary tools like:
NPOI
MyXLS
ExcelWriter (softartisans)
JetCell (DevTrio)
Aspose.Cells (Aspose)
But I do not know which one is better for my needs. I need to export not only grid row data but also Chart (image), thats why I am thinking about.
I have been trying for days now how to create a process to the user to easily create a connection to any installed data types they have installed. I have found an example right inside vb2008. I never use this because I code my own connections, but this would be real nice if I could include it or duplicate it.

View 1 RepliesI currently have a property in my program which returns a true/false depending on if the program is "portable" or not. I need this to know if I should do a certain thing or not.
It checks if it is by checking if the registrykey the installer creates exists, here:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\MyProgram
(And under the Wow node if the OS is 64 bit)
The problem is, I am trying to get rid of the need for admin rights, and this is the last function that needs to be fixed. But I don't have a clue on how.
Why I want this property is because then I don't need two separate versions of my program (like a set property in My.Settings which I set before I build).
The only files that differ using the portable vs the installer is one file, but the reason why I don't want to base the result on the existence of that file is because I want to warn the user if it's not there (if the program is not in Portable mode), so he can reinstall the program.
how I can check if the program is installed by an installer, without using admin

View 2 RepliesDoes anyone know of a way to script falsifying the amount of RAM installed on a PC for an install. I have a program that needs to be installed on many systems that all have little RAM. The program requires during the setup that at least 384 MB of RAM be installed. Some of these systems only have 256 so the install fails. I know the easy answer is install more RAM. Ain't going to happen. Company has no budget. The install should be fine I think, but would like to test more. in order to do the testing to see if this would even work though I need to figure out how to have the OS tell the app it has more RAM than it does. I don't know this app but my first guess is the app queries WMI for amount of RAM?? If that's the case is there a way to set that WMI entry to something different until after the app is done? Or if someone knows another way that would be good too?

So I do not have a clean application that i can uninstall. The shared folder is now deleted, but if I try to deploy locally, the error is thereI installed the app on a third PC in a shared folder and uninstalled it afterwards. I can deploy and start the app on this third PC (but at the moment it is uninstalled there) .What file / entry in a file can I delete that I can install my application locally again (it runs in the debugger of the IDE)?
