I know how to open local .msg files in webbrowser in html format.The problem is when the .msg has embedded pictures, the only thing that appears is a blank space ("picture not found") where it is supposed to be.If I open the .msg file in Outlook, I see the images correctly, but in my program I can't see embedded pictures.

i'm building my own monitoring system. I have allot but i'm stuck at 1 point: I wanna have a list of events out of the event viewer, it polls every 30 min.i have this:
Dim eventLogApp As New System.Diagnostics.EventLog("Application")
Dim eventLogEntry As System.Diagnostics.EventLogEntry
Dim eventCntr As Integer = 1[code]....
but this is way to heavy for a poll of every 30 min. Because is checks the WHOLE event viewer.What i want.. just the latest 5 or 10 events from the event viewer to reduce the load..

I am currently working with a program where the user is prompted to click certain points on a picture within the picturebox on my form. The issue is that some of the points need to be pretty precise and i want to give them controls to slide the points once they have clicked them. The method for sliding is fairly simple but i want to be able to graphically show it in a secondary picturebox.

I have created a drawing viewer that displays CNC files. The viewer itself is a user control that i have compiled into a dll. I added a reference to this dll to a windows application and added the control to one of the forms. I also have a reference to other custom dll's within this project. The application works exactly as expected. CNC files can be viewed by using the File>Open menu. You can open a single file or load multiple files into a buffer that will allow you to scan through them using Next and Previous buttons.
What i want to do is open this viewer from another application but have certain CNC files already loaded into the viewer. I know i could get this working but i don't think it would be the best way. Is there a way for me to include a list of files in a shell command? Perhaps the enitre viewer application should be included in a dll that has a LoadFiles() and Show() method.
I have been provided with a series of RDL files and dataset specifications for each RDL report.I have successfully generated the proper data tables for each report specification but have not yet figured out how to successfully use the reportviewer in my application with the provided RDL files.Due to the large number of reports I will be working with I need to hard code the reportviewer instead of using the control in design mode.
View 2 RepliesI would like to create a pixel viwer (i.e. zoom into a picture to view the image's pixel information - Similar to windows paint or Photoshop). I have created an image zooming code, but it enlarges the image and sadly, doesn't show the blocks of pixels I was hoping for.I have thought of several ideas, but each worse than the next. As an example, re-create the image, increasing each pixel's area based on the zoom-level. But I can tell already that this process would be slow and judging by photoshop (or paint) there is a quicker method.
View 2 RepliesCurrently I'm working on a piece of code that involves using the Crystal Reports Viewer to export .RPT files to PDF. My problem is that the code works on literally everything except the website I'm planning to eventually put it on.
When placed on the website it throws back the error "Failed to open the connection." which I believe is connected to the SQL Server connection that's formed in order to read data for the report itself.
The code itself is solid and works when used in a separate console application I built to test it whether said code is run on my local machine or on the server itself. It even runs when I test the website in Visual Studio's virtual host.
I've narrowed it down to being some sort of permissions issue, but I am not knowledgeable enough in the various permissions settings to figure out which ones specifically apply to this situation. It's worth mentioning that other pages on the website are directly connecting to the same database, but they are doing so directly through Linq instead of going through the Crystal Report Viewer.
So does anybody know which settings I need to modify in order to fix the connection error.An added note: One of the other suggestions is to make sure there's an ODBC DNS in place that matches the one being used by the code. I have created such a DNS already.
I have a tumbnail Control box. Everytime my pictures load i click it will show in Image Viewer or photoshop can i view it in picture box instead of open a new window in other application?

Im looking for an image viewer that supports most types of image formats, including PDFs, and has the ability to rotate/zoom, and draw on an image. I've been looking but to no avail. Does anyone have any suggestions on the best way of going about modifying a control so that I would have these features? The main problem that I am running into is the lack of the ability to draw on an image. Im still sort of a newbie to .NET,

View 2 RepliesI have already posted this question on the "reporting services" forum and received no responses, so i thought i'd give it a try here.
SQL server 2005 SP3, VS 2005, vb.net, RV control.
When i add a background image to the page header, body and page footer, The rendering takes about one second per page. Without the background images, it renders about 25-50 pages per second. My report is a statement print report and has about 1500 pages.
Since it is the same image on each page, why does the server need to send that image over and over again to the report viewer control?
In vb.net i have the Report Viewer control and i bring up a report in normal viewing mode. when i click on the print layout mode, or have that mode set up to be the default mode, It takes forever when i have a background image and virtually no time for the same report without the images. The images are gifs about 5 or 6k each. I have chosen to embed the image into the report.
How do i optimize the usage of background images so they do not interfere with the rendering speed? Or at least minimalize the slowdown.
[EDIT:] I have discovered that if i render it to PDF and open the PDF and page through the report, it is much much faster. In other words if i choose to render to 'printlayout', it is say 25 times slower than when i render it to default, and about 20 times slower then if i render it to PDF. And the PDF contains exact rendering for all pages, exactly the same rendering as the print layout mode generates.

I created a new cursor (it works properly, I tried it in windows 7) but is not working for me in the program.I took the Windows cursor (aero_helpsel_xl, from C:WindowsCursors) and it appears to me the same error.i use with this code:
Me.Cursor = New Cursor("Patch..")
The problem say:: "{"Image format is not valid. Image file may be corrupted.
Parameter name: stream "}"
edit: I realized what the problem ... It can read only cur files with 24-bit color and lower - but it shows only two colors: black and white.

not sure why...i even though I specify system.drawing.imaging.imageformat.PNG
samething with JPG... it actually SHRINKS it evenmore.. example 88KB jpeg.. saved as jpeg is now 47.7KB...
In VB6 you could BITBLT things around before refreshing the screen. In .NET, I'm aware of DrawImage, but that can only be done on a paint event rather than before anything gets painted. The issue I have is, I need to open several files with image data in them and then build a bigger image with those smaller images. Before I could open them, BITBLT them to a Buffer. As far as I can tell .NET offers no way to do this as the only function I've been able to find (DrawImage) only works within the paint event. Is there still a way to do this in VS08 or no?

View 5 RepliesI have an application that can read certain types of files, and I have it working so that if you do "open with" from windows, it automatically starts the application and opens the selected file.
Unfortnately, I cannot get it to work for more than one file.
System.Environment.GetCommandLineArgs() contrains the following:
System.Environment.GetCommandLineArgs(0) = name and path to the .exe
System.Environment.GetCommandLineArgs(1) = name and path to the first file selected to be opened
System.Environment.GetCommandLineArgs().Length is 2 when the user tries to open 1 file, which makes sense since the first argument is the .exe itself and the 2nd is the path to the file, but it does not increase to 3 if the user tries to open 2 files... meaning that System.Environment.GetCommandLineArgs(2) is never populated Here is some sample code that shows the problem: It will recognize no files or 1 file being opened, but if you try to open multiple it will only show the first.
