View 2 RepliesApplication using ado.net
When reading data from an excel file the driver tries to detect the data type of a column based on the contents of that column.
Once it's decided on the datatype then data that is not compatible with that datatype is simply ignored and returned as Null when you read that column using ado.net
For example if most of the column contains numbers then the occasional cell containing non-numeric data is returned as null.
Is there a way to force it to always return all data as text no matter what the actual column contains. ?
I need to download an mp3 file on a linkbutton click event, but i want to force the save or open dialog. I have tried the following code:
Response.End()
When i run this i get nothing, What am i doing wrong? is there any other way to do this?

View 1 RepliesI got two issues getting my application to download a file. One small and one rather big.The downloader seems to have an issue using the users full download capability while the downloaded size is under 1 MB. As soon as it hits that, it seems to speed up with 10-100 times the previous speed.(Snippet at the end of the post)It seems to have to do with the filesize, which is about 5GB. As soon as my application hits about 1GB it completely locks up. (Without an error message, which I do have built in with a try...catch statement)I actually have to force quit the app to make it stop.It works perfectly fine with a 20MB file.I have the idea it's because of the int64's I use. But I need to use those (afaik) due to the big file size.[code]

View 3 RepliesI am creating a windows application using visual studio. I want somehow to insert an excel file into the application so the user will be able to download it from the program and save it to his computer. This means that the file will be a part of the program. There will be a button that will prompt the user to save the particular file somewhere so he can then view it.
What should I do in order to "embody" the excel file to the application? And what code should I write to link the file with the button?
How do we embed / attach a pdf file (100 page file) in one of our form and the users should be allowed to download the same while executing /using this tool.

I usually download file using following code:My.Computer.Network.DownloadFile("url of the file","filepath to save the file")But recently I encountered a site that only allow file download if you click it from its site and not via direct downloading from vb.net code.How to download file from http server that requires a referral before allowing the download?
View 1 RepliesI have written an application for a customer, and the application is run in various locations around the world. The company carefully controls the release of the software to the various buildings where it is being used, and because of this, I have made use of the "Check for updates" feature. The problem I am faced with, is that the folks using this software more often than not answers "NO" when prompted to download and install the latest version of the application. This is unacceptable and ultimately, we'll need to go in and have them manually install the software.
We don't publish updates to the software w/o meaning for them to be necessary, and I find it hard to believe that Microsoft doesn't recognize this sort of thing as being needed when they designed the update procedures. Alas, this seems to be the case.
Is it possible to use the strategy to force an application to update completely every s often to prevent piracy.I mean somenone manage to crack our click once application and make some modification.but inside the application there is some part of the code that make mandatory to update it.in each update all the application is replaced completely in this way the application on the user computer is a clean one and not the cracked one so the checks for seraching for serials numbers are reinstaed is it possibile to use this as technique to prevent piracy?

is there a way to force the application to use more cpu to reduce the calculation time?

I have a server (server A) that has several public IP addresses. I am building a desktop application that will run on server A to fetch data from another server (server B) using the httpwebrequest class.
What I would like to do is be able to programatically direct the application to use a specific IP address from the one the server (A) has.
I need to be able to run multiple instances of a standalone (3rd party) application. This application prevents multiple instances from being ran from within the application. I need to basically override this.
I know it can be accomplished by hexing the original executable, however I would like to stay away from this method as I'd like for other users to be able to use my application from the get go without needing to hex the 3rd party app themselves or me having to send them the hexed app. Is there any way to achieve this or am I just taking crazy pills?
Here's the scenario, winforms application, monitoring via Task Manager Processes Tab.On initial launch spins up to ~61,000K (initial data grid and data loads)If I minimize the application, not touching or doing anything the Mem usage drops to 1,380K.When I restore the application is spins back up to only 5.8K
So my question is, does the minimize send some internal message to clean up resources since the application in question is not in focus?The first app I noticed this in happens to be VB.NET, but I've observed the same behavior in my main C# winform applications.
I need to create a small application that will force a user to enter an even number but i MUST use a loop. Here's what i've come up with:

I would like to try and implement a feature wherby once you have logged into an application (straightforward winforms application) and had your credetials verified the application would then force you to log on again if no activity had been detected in the application for a certain number of minutes. In essence I want to provide some extra security for those occasions when users get up and wander away from their machines for prolonged periods.
I have all the logic for logging into the application, it's just the checking for no activity over a given period and then forcing the user to log back in again that I'm not having much luck with.
I have a backup script i made in VB. part of the code im having trouble with:
HTML
code:
Now this code is executed when a button is clicked, if the folder does exists, it displays a message and continues the backup. however if it does not it displays displays "does not exist box" then i want the application to close.
I played around with the application.exit commands but it seems like the code just skips over it, and continues to try and backup the data, then errors out. how do i make the application close, if the dir does not exist?
Every time I compile my application, during install I get the error:Cannot download application, the application is missing required files
