Web Forms :: How To Get The A Single Constant Value
Feb 26, 2010
I have a function that calculates the exchange rate between two currencies. The inputs are constants:
[Code]....
I have currency codes in my database listed as "EUR", "USD" etc. that I want to use in the function. Unfortunately the function requires a constant value like CurrencyExchangeRate.Currency.EUR instead of a string value called "EUR" How can I turn the value from the database into a usable value for the function?
I know it must be very simple but I cannot figure it out.
I have aspxcombobox. There are so many items with different lengths. If i select Small ones the combobox width is in minimum size and if i am selecting larger length item combobox width is increasing to fit the item in it. any property to set the combobox width constant for any item.
I am building a website that have a number of dropdownlists. The user selects his/her choice and this is sent to a number of companies. Therefore the choice has to be changed to the corresponding value of the individual company i.e value 1 will be coverted to the corresponding value of "AB" for company "x". What way would be most efficent to achieve this. A database seems to be unefficent with the calls to the database. Would a 2-D array in a class be best?
I have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.
While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.
I am trying something apart of my boundries, is there any way to disable a single intem in dropdownlist or stop the ddl change event for a single item.
( header is a custom control -- it simply adds some css by default and position ). In such case quotes marks have higher priority and entire text is sucked as-is, in effect I get header with text
<%= Foo.Bar %>
So, my question is -- what is the syntax to get the value of C# constant, no matter what (IOW -- with highest priority)? Edits:
How would one create a website that would look the same at any resolution? I've heard of making so it will fit for a 800x600 screen but then that just screws everyone that has a higher screen resolution. I've heard about using widths that use percentages and using iframes and things like that.
What's the best way to have one website fits all resolutions?
Im also wondering is there a way I can resize the image upon upload if so, how? And as this is a save as in my fileupload control will this overwrite any folder that has the userid already there? (what I want and need)
I have an Asp.Net website which should have a variable as a string in the url.
The content of the website changes depending on the year. the idea is to have this year in the url in a clean way.
http://localhost/YEAR/index.aspx
I have done this in MVC with routing, but i have no idea how to do it in asp.net I basically need just 1 route I guess. so all URL's will be as they were before (index.aspx, ...) basically in stead of having ?year=2011 behind EVERY url in the website i'd like to have this value in the route.
I am iterating through a dictionay object. And although I added a couple of keys @Microdoft and @Microsoft_Child which I thought were different but when i use the .ContainsKey method it views them as being the same. Should I use ContainsValue method?
I must be doing something wrong here but I can't find an easy way to get this to work. Imagine the following code:
<asp:RadioButtonList ID="MyRadioButtonList" runat="server"> <asp:ListItem Value="<%= CompanyName.SystemName.Constants.PaymentFrequency.FREQUENT.ToString() %>" Text="Yes" Selected="True"></asp:ListItem> <asp:ListItem Value="<%= CompanyName.SystemName.Constants.PaymentFrequency.ONCE.ToString() %>" Text="No, Just do this once"></asp:ListItem> </asp:RadioButtonList>
But it doesn't compile the statement before it renders the page. So if I get the selected value of this radiobuttonlist it contains something like "<%= Compan... %>" instead of what my constant defines.
Everytime I compile my asp .net project it states the following:
'Sessions' does not contain a definition for 'Select'.
In the page this happens on if I change something put it back and save and re-compile it tends to go ok, but at the moment it is happening every time. It does contain a definition for Select I can type it in plus the page does not show an error where this code is and works when it does compile ok?
I am trying to place a right-click menu addin for the asp.net html window.The one I currently have works on the C#/Vb code window...just not in the html code window.
That would get me the context menu (right-click menu) of the non-html code window.But what constant name would get me the html code window context menu?
My website application is developed with Visual Studio 2008. The programming is written and tested with a project saved on my local hard drive. Afterwards the program is transferred to my http site with the Copy Web Site function of VS 2008. Previously Visual Studio always knew the location of the remote web site. It always started the Copy Web Site function with my source site as the http site and the remote site as the site on my hard drive.
Recently, Visual Studio demands that I enter the remote site. Of course, I can do this and cause the Copy Web Site function to work. However, when VS knew the remote web site, it could easily notify me as to what changes had occurred on the Remote site since the last Copy Web site function. This helped me in determining which files needed to be copied to the http Source web site. How can I permanently link my hard drive file location as the source site in the Copy Web site function of Visual Studio 2008?
I was just typing on an old site of mine that requires the constant contact method that uses threading and an update panel to prevent users from being logged out since despite setting the timeout period in web.config to what mathematically should be millions of minutes people still seem to get logged out after like 5 minutes. I tried the web service method, but it was ineffective.
The constant contact with an update panel accomplishes its primary objective well, however when a user clicks on their keyboards back button at the wrong time they get redirected to the previous page and if they click the forward button in their browser the page contains none of their typed data.
Is there a way to override whatever causes the backspace button to do this?
In a situation where we accidentally published an asp.net website, without updatability, with one wrong URL, we'd like to just open that DLL and change the URL, to prevent waiting another week for the next publish opportunity.
In oldish native DLLs I knew how to change resources, but how would I attempt this with .NET DLLs? And is there an easy way, or only a hackerish one (I know of ildasm and ilasm)? If it matters, the string is a literal inside an event handler.
For context: First of all, I am new to LINQ, as I have been using SubSonic for quite some time now.
I have two tables, Users, and Affiliates. They both have a very typical schema. The FK that joins them is the UserId field, which is in the Affiliates table. I want to create a LINQ query that pulls the Username from the Users table using the AffiliateId value. The AffiliateId is a primary key of the Affiliates table.
I have tried to accomplish this using many variations of the following code:
[Code]....
In the above query, I expect to get a single row result set. However, I instead receive the entire table of results.
How can I make this work? I have yet to see an example or article out there to do what I am trying to do.
I have huge excel files that I have to open from web browser. It takes several minutes to load huge file. Is it possible to open a single worksheet (single tab) at a time from excel file that contains many worksheets? I have to do this using C# / asp.net MVC
