Using Preprocessor Directives In Web Services Project?

Sep 7, 2010

I am writing a web services project in C#/.NET 3.5 / VS 2008. I declare several constants such as: private const string var1 = "hello"; I'd like to change the value of this string when testing, so I put a #TEST directive on top of my .cs file. But I cannot do:

if (#TEST)
{private const string var1 = "hello test";}
else
{private const string var1 = "hello";}

in the variable declaration. It will not compile. I do not want to change the value in various functions because there are too many functions using the value.

Preprocessor Directive For ImgUrl Property Of Image In C#?

Use C# Constant In Page?

Sep 27, 2010

The examples given below could make little sense, but it is because I am focusing on syntax. Let's say I have such C# code:

public static class Foo
{
public const string Bar = "hello world.";
}

Now, I would like to use Foo.Bar constant in ASP.Net instead of typing each time "hello world.". So I used this syntax:

<p><%= Foo.Bar %></p>

It works. It works also in such cases:

<p>"<%= Foo.Bar %>"</p>
<p class="<%= Foo.Bar %>">the weird, nonsense example</p>

So, it works with quotes too. However I have also cases, when quotes get higher priority:

<custom:Header runat='server' Text="<%= Foo.Bar %>"/>

( 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:

<custom:Header runat='server' Text="<%# Foo.Bar %>"/>

(note hash instead of equal sign) does not work as well.

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.

Constant Screen Resolution For All?

Mar 17, 2011

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?

Keep A Constant Table Size?

Nov 23, 2010

I currently have a table that has a few hidden text boxes... The text boxes become visible when certain actions are performed.

The table though changes size according to when the textboxes are visible or now. Ex. When the textboxes are visible the table grows, and vice versa.

I would like to keep the table size at its max size ( size when the text boxes are visible) even when they are not.

Using A Constant String In URL Using Url Rewriting Or Routes

Feb 9, 2011

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.

Set ListItem Value To Constant For RadioButtonList In ASPX

Sep 23, 2010

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.

Configuration :: Constant Compile Error That Isn't True?

Mar 25, 2011

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?

Web Forms :: Storing A Constant Table In Database For Reference?

Jun 30, 2010

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?

Visual Studio :: Copy - Constant Remote Website

Jan 7, 2010

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?

AJAX :: Hitting Backspace With Constant Contact Causes Previous Page To Load?

May 14, 2010

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?

Deployment - Living On The Edge Can Change A Constant String In A Deployed Website Page Dll?

Jul 27, 2010

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.
