Using The Web Browser Control To Generate Screenshots Of An Intranet Application Developed In ASP.NET
Mar 21, 2012
I am using the web browser control to generate screenshots of an intranet application developed in ASP.NET.
The screenshot is generated, compressed and then stored as a BLOB in the database. When I developed this facility I investigated the best way of compressing the image (to the lowest byte size), however the images still seem to be too big as the database table is growing larger than I hoped. I am using the TIFF format, but I am now thinking that this may not be the best as it is used by photographers (who I assume require good quality photographs). Here is the code to compress the image (before it is stored as a BLOB):
I ve developed a salary calculating software using vb.net.... Its working fine and i ve converted it to an exe file... My drawback is it can be copied and pasted in another system very easily... I want to generate a key for the exe file and while installing the key should be used and when installation is completed ,the key should not be used again
I am trying to create an application that records screenshots every 50 milliseconds... And It works below:
Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick Dim b As Bitmap = New Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height)
[Code]....
But after 30 seconds I see an ArgumentException on the second line...
Does anyone have a solution or an alternate method of capturing the screen like this?
I have an intranet asp.net application and when a page is loaded, i want to log the IP Address, Computer Name and the Windows Account(from active directory) currently logged into the computer from which the page is being accessed.
So far, Im able to get the IP address and computer name but the windows account, am getting NT AUTHORITYSYSTEM
I would like an automatic way of updating desktop application using Http over the company intranet. Also it much have to be used by VB6 applications as well.
How can an application, running on a production server, access the login username of the machine that a user is accessing an application from? For example, I am currently logged into my machine on the INTRA corporate intranet. My username will be INTRAUsername. I have added specific usernames to a database and wish to check this intranet username against the database to restrict access to an application and leverage the username across the application.Currently, I am using the following code to access the username:rivate username As String = Thread.CurrentPrincipal.Identity.Namehis is working great on localhost, but when authenticating against the database on a development server, I'm getting the following error:
I have a working Visual Basic application. I wish to have a html page that displays how to use it. How do I link it into a web browser control? This will be published and can't be just typing in the directory name as it may not exist on the client computer. How do I get it to look for the file in my solution explorer? I am using WPF in visual basic 2008 EXPRESS.
I am trying to create an application that will login our company's intranet portal via a webpage. The webpage has a single frame in it that loads a secure(https) login form. After logging in, the application will need to read and send xml to and from the portal. I have been digging around and have seen a few different ways of submitting the login information from the program to the site, however, I have not gotten any of them to work. From what I can tell it is difficult to change the values of input boxes that are inside a frame. Am I accurate on this? There will be a large amount of data transfer between the app and the portal so I will need something lightweight but I have enough room that I would rather not reinvent the http/web-browser wheel if at all possible. The reason I say that is because I have read that some objects that handle web pages are very resource hungry. I have no preference on the .net frameworks as this is the area of VB thats kinda confusing. What I am looking for is either a point or violent shove in the right direction.
I have developed an application in Visual Basic 2008. I really love the product.I am 99% done but am hung up on a Publish issue.I know the Publish feature is not a full install program - but it handles downloading the application prerequisits so well I really want to use it.My problem is the Install path. It installs my application is the strrangest drectory appdatalocal 615252-191891-919 (goes on for ever)
I can set the install directory to something simpler. Would love to get it in Program Files but will settle for AppData if it can be a reasonable directory name. If I have to tell a customer to look in that directory for some reason I would have to read off about 60-70 alpha numeric characters for the directory path - that isn't feasable.
I've developed a very small in-house web application with visual basic on VS2010. Can anyone give me any advice or literature s to how i can put the site on a server?

I am writing a desktop app in VB.Net, and I'd like to include a web browser control to automate certain functions the user might have to perform in the browser. I have to render the page so I do not want to use the webrequest to make direct calls. When I publish the app, do I have to be concerned with which version of Internet Explorer the user has on their machine? Are their any third party, freely available, stable web browser controls available for VB.Net that people are using?
I'm using the web browser control in vs2005 to show a web page which has flash. somehow, it shows error:"this program requires flash.ocx which is no longer included in this version windows".

Is it something dealing with the permissions set with the database server or something? I am new at .NET programming and I have been spinning my wheels on this for the past couple of days and I am at a loss. From what I research, this error should only occur if I was creating a web program, but I am not. It is a windows application.
I have developed a windows application which performs a series of database operations like select, insert, update. I am connecting to Oracle database and its working fine in development system. But, when I deployed this application, I am getting error at StartConnection (which opens the DB connection). After installing OracleClient in client system, its working fine. Now, my question is that do I need to install OracleClient to every user? If so, it will be hectic to do so as its size is around 200 MB and its not possible to ask all the users to install it just for a small application. I have tried adding some OracleClient files like orannzbb11.dll, oraciei11.dll, iraops11w.dll etc. But in vain! Could anyone please suggest me a work-around or a way to accomplish this?

I have developed application using VB 2008 and develop a MSI setup for installation. Now problem is on windows 7 it generate a warning message on installation of software that "The publisher is unknown", but the software install well on continue of this warning.When I run the software it did connect to Access database which is on installation directory, but it didn't allow to insert or update any data in the database.

I would like to inform you that i developed fully functional application at client area . and then we need to create another application with some different functionality my problem is :

Im using VB2005 express and the app im creating uses the web browser control.Basically I want to know if its possible to make the web browser control connect through a different ip address and port from your default web browser.
I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?
I currently have a simple crystal reports application which generates a crystal report and in the built in viewer provided by VS2005. There is a drop down where you can select options to change the criteria of the report. I wish to convert this app to a windows executable which will take all those select options and generates pdfs based on the crystal report. the executable will be triggered by windows task scheduler...or maybe command line app?
Obviously this will be somewhat of a re-write. What would be the best way to start this as? a crystal report application or a windows application.
