Hi, im trying to use the webcam on a webpage, I created the control in C# , when working with a normal windows form app, it works fine , displaying the image that it gets from the webcam, but when i convert it into a activex control so that i can use the functionality on a aspx page , the webcam gets initialized but i only see a black box where the cam feed is supposed to be, ive tried a lot of ways now but i cant seem to display a picture in the picture box in the activex control, it just stays black, so if someone could please assist me in do this, either how to use the webcam on a aspx page or how to display a image saved on the client pc (when i save an image on the client pc with the activex control it saves fine, it just does not display on the page) I need this to take pictures of employees ect via the website

now what i want to do is like the same way you use the panel to place something inside , i want to use my custom control just again , its a popup window and i would like to use some sort of place holder where i can place stuff in for e.g. i would want to use the window for error messges or to put in a few textboxes and labels. like this

Please could someone help me I want to create a popup window. Now i've created the window in a ascx file. Now what i would like to do is make the control work like other asp controls for e.g.

            ......

what i would like to to is add whatever into the content space. I dont realy know alot about creating my own controls but is this posible??

I'll sugest using session objects, it's the easiest way. oh and if you didn't know , you can place any type of object into a session variable you'll just have to convert it back to the type of object you want when you use it, and another plus , its value can be used on any page.

If the database is on the pc you are coding on , change >> Data Source=SERVER\SQLEXPRESS to Data Source=(local)\SQLEXPRESS

Ok so no reply from anyone, so I'll leave what I got When using network resources the asp.net "user" doesn’t have the required rights. So , what you need to do is impersonate a user on the sever having the rights the access the network . Create a class, call it whatever you want, I’ll call this one impersonation and add the following: Some of the imports won’t be needed

Hi everyone I have searched the whole day long now and cant seen to find, maybe searching in the wrong places:confused: If someone could please help me I have a aspx vb project using crystal reports, now what I want to do is , when the user hits the print button the report should print to a printer shared on a computer connected to the network. Now this is working when I run the app in visual studio but when its published to the iis it gives me a "access denied" error when i set the printer as \\pcIP\printername , or when i view the printer queue it says, "error - printing" when i set the printer as a normal printer on the server giving it a new port looking at the same place as before this is how i do it create a report doc -> rpt rpt.PrintOptions.PrinterName = "\\IP\printer" rpt.PrintToPrinter(1, False, 0, 0) any help would be great

Thank you , I'll look into it, got fed up with all the security restrictions, made a exe to install all the fonts , gave the user only the option of running the app and not downloading it, used this tag to modify the download dialog

Is there a way of removing or hiding the menu bar and address bar of the browser without using a .hta file or doin a javascript window.open, I want the web app to look like its running inside a normal window

I found some script to do it but it only works on server side Dim objStream objStream = CreateObject("ADODB.Stream") objStream.Type = 1 ' adTypeBinary objStream.Open("URL=http://10.52.223.67/PPE/Font/FRE3OF9X.ttf") objStream.SaveToFile("C:\Temp\FRE3OF9X.ttf", 2) ' adSaveCreateOverWrite objStream.Close() objStream = Nothing Const FONTS = &H14& Dim objShell Dim objFolder objShell = CreateObject("Shell.Application") objFolder = objShell.Namespace(FONTS) objFolder.CopyHere("C:\Temp\FRE3OF9X.ttf") on the client side I get the following error System.Runtime.InteropServices.COMException: Write to file failed [COMException (0x800a0bbc): Write to file failed.]

The site is only going to be used inside the company, so no worries about unwanted stuff to be downloaded, The font I need is for a barcode and its nog going to be the same all the time, its for label printing. I know the easiest way of making sure its on the client side is to manually installing the font where the app is going to be used, but its not allways going to be guaranteed the user will be on the same pc, so in that case if the font is not dedected it must be placed in the Windows/fonts directory

I have a aspx vb project, im testing to see if a certain font is installed , if its not it should be downloaded and installed on the client pc, is there some way of doing it in the background without the client user knowing of it being done, or any other suggestions are welcome thanx

I'm using a type of barcode font, if the font is not installed on the client pc the browser uses a default font I used 2 spans on the default page( hidden) with a series of characters If the length of the two spans are the same with the font is not installed on the client pc,
