Web Forms :: Image Button Returns Incorrect Coordinates?
Oct 27, 2010
I have an ImageButton which sometimes returns the wrong coordinates when clicked. So far I have seen this problems only on one particular computer but on that system it is consistently out by a factor of about 1.25. The dimensions of the ImageButton are 300 x 450 but clicking in the lower left corner returns 374,562. However, if I raise a button click through code the correct region of the button is accessed and the correct coordinates can be recovered. The browser is IE running under XP SP3. On other computers with the same browser and operating system there is no problem but I don't know how widespread the problem could be. It is not affected by altering the screen resolution. Has anyone encountered this before? Is there a way to test and calibrate an imagebutton (without asking the user to click somewhere special first)?
select UM.USER_NAME, RM.ROLE_ID, RM.ROLE_NAME FROM [MICommonDB].[dbo].[ROLE_USER_MAPPING] as RUM join [MICommonDB].[dbo].[ROLE_MASTER] as RM ON RM.ROLE_ID=RUM.ROLE_ID join [MICommonDB].[dbo].[USER_MASTER] UM ON UM.USER_ID = RUM.USER_ID where UM.USER_NAME='useruser' which is giving me proper result(i.e., 2 records) when running in SQL server.
Now I have created below method in a class with same query (I am calling this method inside Controller):
public IEnumerable<RoleUserDO> getRoleNameByUserName(string userName) { IEnumerable<RoleUserDO> strResult = null;
strResult = (from RUM in oDBContext.ROLE_USER_MAPPING
[CODE]..
but it returns only 1 record instead of 2 records(when compared with DB query)
I have a specific requirement of extracting text and images from a specific area in a pdf file.The area might be a selected or highlighted or from a given set of coordinates.
When i went through, all the approaches are to extract images and text entirely from the PDF on not in a specified location. I tried with iTextSharp,Syncfussion,Apose but couldn figure out a better approach for this.
I am trying to design a website in asp.net (just learning) and am having trouble positioning div's on the .aspx page.
I normally design in dreamweaver where you can move the div around freely and it sets the x and y coordinates for you but I am having trouble positioning an image.
Do you have to type the x and y coordinates in yourself in the code behind or in the css or is there an easier way where you can freely move the image around and it sets the coordinates.
my web Form contain Gridview : when i click the button woth ID="IncreaseButton" , i have problem is : The Initial price = 334,7 now When i click button to Increase the price with 1.5 , i got this value :
I have a log-in panel that when a user is logged in will show a Log Out button. Only problem is when I go to debug I get the error message:
"error BC30506: Handles clause requires a WithEvents variable defined in the containing type or one of its base types."
This is my back-end code:
[Code]....
And this is the front-end:
[Code]....
The log-in button works fine and I was just wondering if any of you could spot what is wrong as it looks like it should work perfectly as it is the same as the log in button.
Like Windows' environment Openfiledialog control, is there any way that I can create a file browse button that will let me select a file and return the path and filename to a variable or a textbox or any other object?
The webform will contain two controls: a regular button that I will use to browse and select a file, and a gridview.that will display a list of the files that I've selected with the file browse button.
Let's say I have a LatLng , is there any way of checking if it represents a possible location within a city? How can I get the limits of a city? I'm using Google Map.
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.
The problem of this solution is that the programmatically added nodes are not visible
2- As an alternative for ImageButton I can use a panel to display the map (BackImageUrl="~/Images/map.jpg"). after creating the btn programmatically I use the following code to add it to the panel:
Panel1.Controls.Add(btn);
Hear the problem is that I cannot capture the coordinates by clicking on the map.I need to enable the user to add the nodes to the map and view them in a single interface.
Just wondering if anyone has ever managed to find a way to have a datagridview image button column in a template field which display different images on different rows depending on some data element in the row. Our application needs to display a series of fees charged against an account column which will be either less then 500, 500 to 1000 or >1000. Some of those fees are charged at a full rate, others at a partial rate, and some are not charged at all. The user would like to see a simple 3-state graphic which would convey the simple info: full-charge, partial-charge, or no-charge. Sounds easy enough but I've not yet managed to find a way to do this. Every time I attempt to modify the individual cell's graphic it seems to want to change the graphic for all the rows.
I was wondering if anyone has done this. I'm writing an application which parses latitude and longitude into a database. When presenting this information to users I would like them to be able to click on a button which would show them the location in google maps.
Alternatively I could just give them the link to google maps into which they can click on and open a new browser window...
I am trying to change the image url of an image button in my gridview. I cannot seem to be able to do this in the code behind. Is there a way I can do this through the image buttons controls?
I am new to .NEt, I am doing a classifieds website and tried to save the image in server,in a seperate folder and stored that address in MS access databse.when I wanted to display that image in a gridview,its not showing the image.
In the seperate column when Ia m trying to see the image location using bound field,its displaying C:websitesAzangouser_images j.jpg, but where as its not showing the image in the item template field.
I'm trying to rescale uploaded jpeg in asp.netSo I go:
Image original = Image.FromStream(myPostedFile.InputStream); int w=original.Width, h=original.Height; using(Graphics g = Graphics.FromImage(original)) {
I have four Imagebuttons that I want to disable depending on the Role the user belongs too. I know how do do this in a gridview or detailsview but for some reason it isn't working on just a plain form. So when a User who is not in the "Admin" role logs onto the page he either doesn't see the button or the hyperlink has been disabled thus not allowing him to proceed any further.
Is there a way to make an image button look like a toggle button? I want it to specify the image for checked and unchecked state. Either that, even if it doesn't look like a button, I'd still want to use custom images instead of the standard dot inside a hole.
I want to learn a user's location from his mobile device by web application.
When user opens the website, with the help of a script we will learn if the device has a gps hardware.And if the device has gps hardware what are the current coordinates?
I have an ASP.NET page (using ASP.NET AJAX and the Telerik RAD components) that provides a data table and an option to download data in CSV format.I have a requirement that a single button allow the user to download a data set. I have a system set up that's nearly working for me based off the solution in http://stackoverflow.com/questions/104601/asp-net-response-redirect-to-new-window
This actually works quite well. When I click the 'Export to CSV' button, the page's UpdateProgress kicks in and my loading overlay appears (it's a CSS div that covers the window when visible). This can take some time depending on the data set (potentially several minutes), at which point I'm getting a window popup with my file.
I am working with a sql server database with about 50 stored procedures. The database and stored procedureswere not created by me. The stored procedures all begin with a number in their name.
Example: 17P_Comsetter
The problem I am having is that if I try and execute the stored procedure at the command line in Query Analyzer,the query analyzer appears not to like that the stored procedure begins with a number. For example:
If I try an run the stored procedure as follows:
EXEC 17P_Comsetter
Then I get the following error message:
Msg 102, ..... Incorrect Syntax near '17'
I am using SQL server 2005. Does anyone know why I am getting this error message?
Here is this thing which to me looks possible, but when I searched over the net I couldnt find anything.
I want to create a page where I can upload an image using any upload function and then display it. Now after diplaying it I want to select the hotspots for an image map. The coordinates of image map values are stored in a database.
Basically I want that to create image maps and hotspots I dont use any offline software, this work is successfully completed and working perfectly, but i want generate one identification where i click the hot spots position in image or CSS file Generate for user identifications, So how can i solve this problem.
I hope You are clear in that what I am looking for.
I started a website based on the NerdDinner source code, everything worked fine (more or less) but whenever I post an event, it ends up on the exact same coordinates on the map regardless of the address (Somewhere in the Gulf of Guinea!)
No idea what to do: I didn't alter the map code at all!
