View 4 RepliesI 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'm making a program to protect custom game files from being copied as best I can, however there are a couple things I need to account for. Some of them I have, others, I have not been able to find information on. When the files are not in use, I have them fully encrypted and hidden from the lay user through a bunch of other tricks (+s attribute, for example). However, I would also like to prevent copying these files while they are being used by the game - obviously I cannot have them encrypted while the game is attempting to read from them.
This opens up a hole, which I have also tried to deal with, but I know my attempts in this regard are less than thorough:
Stop several known well-known copy programs from operating during operation, that being Windows Explorer, Teracopy, and cmd
Now, the other solution I was thinking of was a filesystemwatcher object scanning the better part of the computer for any copies of these files located outside of the "OK" directory, but I'm a bit skeptical as to whether or not this would be very efficient. Any ways to make copying these files difficult without rendering them unusable to the program.
I need to generate a list that I can copy and then paste into a Word Document. I tried using a listbox, but I couldn't copy from that. Basically I don't want to have to type 200 different numbers and I thought this would be quick and easy to write, but I'm stumped. I need the list to be generated in this fashion and it would also be nice if it was all in one line:

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.

View 2 RepliesI 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?
