View 4 RepliesThe urls on my site can become very long, and its my understanding that urls are transmisted with the http requests. So the idea came to compress the string in the url.From my searching on the internet, i found suggestions on using short urls and then link that one to the long url. Id prefere to not use this soltuion because1) I would have to do a extra database check to convert between long and short url.
That leaves in my head 2 options1) Hashing, i dont think this is a option. If you want a safe hashing algorithim, its going to be long.2) Compressing the url string, basicly having the server depress the string when when it gets the url parameters.3) Changing the url so its not descriptive, this is bad because it would make development harder for me ( This is a 1 man project ).Considering the vast amount posible amount of OS / browsers out there, i figured id as if anyone else has tried this or have some clever suggestions.If it mathers the url parameters can reach 100+ chars.Example: mysite.com/Reports/Ability.aspx?PlayerID=7737&GuildID=132&AbilityID=1140&EventID=1609&EncounterID=-1&ServerID=17&IsPlayer=True
EDIT:Let me clarify atm this is NOT breaking the site. Its more about me learning to find a good solution ( Im well aware this is micro optimisation, my site is very fast atm ) and making my site even faster ( To challage myself, and become a better coder ).There is also a cosmetic issue, i personaly think that a URL longer then the address bar looks bad.
I agree that the best way to shorten the ViewState is to disable it on the ASP.Net controls that don't need it. Keeping it small from the beginning is a great habit.I have also heard that it is already compressed (although can be true... there are ways of compressing it even more, has described in this Stack Overflow question).
My question here is not if it should be compressed... is: when should ViewState be compressed?If we have a ViewState of 410 characters it will weight 410 bytes in a page, while a ViewState of 13.843 characters equals 13.5 KB.13.5KB is a considerable weight already. And if I compress a CSS file that height 10KB, I think it is also worthy compressing a ViewState of 13.5KB, even if that means a little extra "thinking" on the server.But is 410 bytes of ViewState worth the extra processing on the server?
working on a client's website that has a gallery and uses a thumbnail.aspx page to shrink images on their site for product galleries. However, they want to move the image files to another URL so I need to modify the thumbnail.aspx code to use a networkstream, but I'm not sure exactly how to do this. Could someone point me in the right direction?
View 2 RepliesI need to write a routine which uploads a largish (2-4 meg) jpg photo and shrink it down to a small size. Adobe image ready does what I need but I need to develop it in my web application. Basically I need to reduce the image file size so it is web friendly.
View 9 RepliesI have a few websites that should access a central location (folder) on a different domain that stores pics. In previous version of this system I stored each pics folder under the same domain and I could access the files with FileInfo
Dim fi As FileInfo = New FileInfo(MapPath(img.ImageUrl))
How can I ger the file info for a file in a different domain ?
In the past, with pages with large viewstate I have overridden the PageStatePersister class so when the state is saved I compress it. On Load I decompress it. I have haven't really thought about it, but could IIS handle something like this better? The reason I did this was to keep my pages slimmer because I have a lot of custom controls on the page and the viewstate was huge. This is where I got my original code from:[URL]

Am building an app in VB.NET | ASP.NET 4 | SQL 2008 R2I am building an site that will potentially have upto 15, 000 pics for now.

Basically like a photo album

View 1 RepliesIn our application we are using forms authentication, we have given defaulturl also in the config file. But the problem is that it is not getting redirected to the default url when the session timeout is occuring.
View 2 RepliesI have been presented with numerous word and excel docs. The goal is to put them online and bind to a database for the fields and also to store data for easy searching and reporting.
Has anyone done anything like this before?
I know the easy solution would be to create a database table for each particula form and also an ASP.net page for each form.
But then there are problems like printing and correct formating so it fits on the page, spaning multiple pages and so on.
And also is there any advice on how to write to PDF straight from the page?
I have a treeview named Treeview1 with checkboxes. I want the child checkboxes to be checked if parent is checked.
I am trying to use a simple code that I found on msdn :
[Code]....
For some reasons I got this error and I really dont understand why:
Type 'System.Windows.Forms.TreeViewEventArgs' is not defined.
warning BC40056: Namespace or type specified in the Imports 'System.Windows.Forms' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.
Really getting better with VS, but I've mostly been displaying data. I'm on a new project and now and I have a lot of data entry forms to create. I created a form to enter data into an access db and got it working. I thought it would be cool to add an edit button that fired a gridview to load on the same page, under my original forms, so that that they could load up the data and edit or delete mistakes. But when I try to update the gridview, it also tries to post the original forms (text boxes), which fail because there is no data in them, and I get an error.
What is the proper way to handle this in asp.net? I'm sure this is kind of a common issue. I've done some searching, but the search terms, like forms and gridview, are kind of generic and I'm not coming up with anything useful. I just need a more experienced person to point me in the right direction and I'll get it figured out.
I do have combo box on my page where the items are retrieved from database.
I have an link label which leads to new form to add value for corresponding column in database.
After add the value, when i click refresh on my current page, the values in combo box must be updated.
I have used this
private void button3_Click(object sender, EventArgs e)
{
this.Refresh();
}

Is there a way that I can create one form and reuse it across multiple projects?
I am using forms authentication, and for some reason it shuts off my images. I have tried putting them in the same directoy, and still nothing.
If I turn off forms authentication, they come back alive so I know my urls are correct.
My images show up find in design time, and if I have logged in and go back to the page, they show, but upon initial login,they aren't visible. What do I need to do?
View 1 RepliesIn windows forms, there is the "show data sources" under the "data" menu item, and I love it because I can drag and drop the fields I need onto the form and it makes the control automatically.In web forms however, this option isn't there. Why? I try to drag and drop fields from the "server explorer" but it generates grids, I don't want grids I just want to drag and drop the text boxes or checkboxes etc.
