View 1 RepliesI use image control in my page and i set Height=100px and width=100px for it
When I set imageurl fo this control it convert my image size to Height=100px width=100px
But I want it small my image Proportional my image scale i mean that if my image is vertical it small it with out change it's scale .
I have images of big size. I want to resize them according to their width and height. If width is bigger than height then maximum width will be 650px and height will in proportion of width. If height is bigger than width then maximum height will be 650px and width will be in proportion of height. How I will resize images proportionally using handler in ASP.Net,C#.
View 1 RepliesI have a Base64String (format: data:image/png;base64,) that is collected from the form.
I want to change it to string and check the color value (RGBA) for the comparison. Therefore, I use the following coding:
[Code]....
However, I find that the array only contain (byte)[5811]. But the original image is 300 * 100. It should be 30000 bytes. How can I get the original image pixel value correctly?
I've been struggling for the past couple of days to get this right. I'm in the process of building something that takes a whole bunch of geographic points, builds a heat map from the data, then overlays it as a tile on Google Earth / Google Maps. A bit like this: [URL]
I have all the heatmap functionality nailed using random xy points. The last part is doing the actual conversion to convert my real lat/lng pairs into x/y pixels to be rendered onto the heatmap image. Lets say I the image is 500px x 500px. I know the min and max values for the lat/lng points, so technically I need to divide the spread between the pixels to get a pixel value for each degree based on the top left pixel of the image (0,0). I've been through so many examples, but I just cant get them to work. The last one I tried was this:
[Code]....
I feed data into my heatpoint function using these 2 functions above like this. Here's a set of 4 points:
[Code]....
The problem I get is that the result is the same for all the points - they all get plotted to exactly the same point. Now, the data is fairly localised, so I dont really need to take the curvature of the earth into consideration.
I am currently developing an iPhone app that will work as a security check-in system for events at a church. The main goal is to be able to search a pre existing MS SQL database for a participant, and then save them to a list on the iPhone/iPod Touch/iPad. Easy enough. One of the fields in the MS SQL database is of Image data type, and its function is to store the participant's image in binary form. I currently am not allowed to switch to varbinary(MAX). From the iPhone, I use:
UIImage *image = [UIImage imageNamed:@"nameOfImage.jpg"];
NSData *imageData = UIImageJPEGRepresentation(image,1.0);
NSString *imageString = (NSString *)[[[NSString alloc] init] base64StringFromData:(NSData *)imageData];
You may be wondering what the base64StringFromData is. It's a category discussed here, Any base64 library on iphone-sdk? In the category, it returns a string as NSASCIIStringEncoding. I then send that string to a Visual Basic web service using POST. Assume in the following that I have already set up and opened my SQL connection, and initlialized a SQL Data adapter and command. So the function looks similar to this:
Public Function sendCommand(ByVal image As String) As String
Dim commandString As String
commandString = "insert into phoneApp(image) values(@image)"
Dim encoding As New System.Text.UTF8Encoding
sqlDataAdapter.InsertCommand = (commandString, sqlConnection)
sqlDataAdapter.InsertCommand.Parameters.Add(@"image", SqlDbType.Image, image.length).Value = encoding.GetBytes(image)
sqlDataAdapter.ExecuteNonQuery()
End Function
Now, finally, here's what is happening. In another function, I call Response.BinaryWrite(SqlDataReader.Item("image")). In Internet Explorer, doing this would then make the image appear in the browser. Instead, it displays the string in base64 form. Copy and pasting that string in a base64 converter off the net, and it works. So the encoding on the iPhone did encode to base64 properly. Here's the question. Do I even need to be encoding to base64 to save into Image Data Type, or should I be focusing on learning how to encode the NSData into a different binary string?
Working on a new site design in asp.net with master pages. Header of the page is a 35px tall "menu bar" which contains an asp menu control rendered as an unordered list.
The selected menu item is styled with a differenct colored background and 2px border around the left top and right sides. The bottom of the selected menu item should line up with the bottom of the menu bar so the selected "tab" looks as if it flows into the content beneath. Looks fine in firefox and IE but in chrome the "tab" seems to be 1 pixel higher than the bottom of the menu bar.
EDIT:here is the css for the menu...
div.hideSkiplink
{
width:40%;
float:right;
height:35px; [code]....
The selected classes are added to the li and a elements via jquery...Here is a screenshot of the problem...The chrome example is on the top and u can see 1px of red border below the tab. On the bottom is the firefox image where everything looks OK.
EDIT:After playing around with this a bit more, I have discovered that it is actually the "header" div itself that is growing by 1px in chrome... This seems very strange to me.

Im after some advice on date format conversions. I am working on a project that has raddatepicker controls that will take values chosen in the UI and uses them as constraints on a SQL query going back to the database.
My problem lies in the fact that the UI has a sensible date format (dd/mm/yyyy), whereas the database stored dates as "the number of seconds past 00:00:00 01/01/1970". In T-SQL, I can convert using:
[Code]....
I have no idea how to achieve this same conversion in C# so the user can choose a friendly format, but subsequently pass back the database date format.
I have a web page which generates a .CSV file based on some user input. When this file is downloaded by the user, the file is being automatically converted to .XLS. Any idea how I can prevent this?
For example, I am redirecting the user to the URL of the generated file, like below URL:
http://localhost/reports/Work/aa.csv
But the download window appears to download "aa.xls"!

I've asp.net 2.0 ajax enabled web site in which I used Ajax update panels in pages. Now I want to convert it into asp.net 3.5 but it gives errors for Ajax tool kit and script manager and update panel used in pages. I don't want to remove ajax functionality from my site, so is there a way to convert them without removing ajax update panels from pages. On my PC I've installed both VS2005 and VS2008.

View 6 RepliesI am totally desparate with the task of Video Conversion, uploading & streaming. I have gone through various articles, posts, blogs and code snipped but couldnt find any full working solution for that.I was advised to work with ffmpeg and i got the functionality [URL]but later i come to know that most asp.net servers (including mine) do not allow to ffmpeg on the server.
Then i look for other solutions, some are saying to convert video files manually and then upload to website (funny hannn). Some are suggesting other site which can store our video and stream from there servers .....So i am stuck now and dont know where to go. I need a complete solution of this problem. Like Users could upload a video file (of any format or at least a good number of choice for upload file format), then they click an upload button and video conversion (e.g. to .flv took place) and the output should be displayed to a user in video player (showing our own logo, not youtube logo....etc.) and thats it.I will definately appreciate all of your comments and guidence.

Though it is usually not a big deal to edit the source code to accomplish this, I am just curious if there is an easier way to reverse the conversion of a column to a TemplateField. The covnersion can be done by a simple click. Is there a similar click to reverse it?
