I want to make a data url from an existing file on the system.
@Convert.ToBase64String() wil do the trick but how do i convert a 'webimage' to a byte array?
Or is there a project to convert 'anything' to a data uri?
How to keep the image transparent zones with WebImage require?
I saw that this function may require an image from a data base or from a file.
[Code]....
But when I call the image, the transparent parts changed to black.
Is there any way to keep the transparent areas of the image?
How would showing the picture in real size?
I'm trying to use the WebImage (included with in assembly System.Web.Helpers with MVC 3 RC2) class to manipulate images, like cropping, resizing, etc.... I've found that when using with PNG images with alpha transparency the result of the transformation is rendered with black background or with bad distortions; that problem happens only with transparent PNG, other file formats are ok.
View 2 RepliesI'm trying to convert a string to decimal but I get this exception:
Exception Details:
Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'string' does not contain a definition for 'AsDecimal'
Here is the code:
decimal PriceHT = 0;
var PriceRequest= "SELECT * FROM Price_" + HttpContext.Current.Session["PriceTableId"] ;
foreach (var Price in Database.OpenFile("Base.sdf").Query(PriceRequest)){
PriceHT = PrixceHT + (Price.PT).AsDecimal(); //Price.PT returns a string
}
I've found a Webmatrix help article that says MS Webmatrix "publishes the (SQL Server or MySQL) database by creating scripts that run in a database that has been created for you by your hosting provider." That is wonderful, except I can't get it to work when I'm trying to publish a MySQL database (backing wordpress) through FTP (my hosting provider does not support 'web deploy'). Again, no problem, since it is already documented that " FTP protocols cannot be used to publish MySQL database. " But this does not excuse Webmatrix from generating MySQL database install scripts for me. During the publishing step, no database install script is generated - at least that I can tell - and there is no manual option to create a database export / backup / install script.
In short, as Webmatrix goes, I'm dead in the water trying to get my database uploaded to my hosting provider. Does anyone know the trick to force Webmatrix to create the MySQL database install scripts on my local box? Once created, I can take-over the upload and install process.
I'm wondering if it is possible to include Microsoft.Data.Entity.CTP.dll reference to WebMatrix site and if the Compact edition of the database would support it? I'd kinda love use something like
code-first development in my WebMatrix project. I think is even easier than writing SQL-s into the code...

I struggle with publishing 2 databases from WebMatrix using WebDeploy. On Publish settings screen I specify 2 different connection strings, but on Publish Compatibility screen Database names in both destination connection strings are equal. When I return to settings screen, original value is replaced there as well.
How destination server connection strings are evaluated? Here are connection strings from the root web.config file, which are set by hidden parameters in my parameters.xml:
<connectionStrings>
<add connectionString="Server=(local);Database=xxx;Uid=xxx;Pwd=xxx" name="xxx" providerName="System.Data.SqlClient" />
<add connectionString="Server=(local);Database=xxx2;Uid=xxx;Pwd=xxx" name="xxx" providerName="System.Data.SqlClient" />
</connectionStrings>

I downloaded WebMatrix thinking I could create a local Intranet page and simply host it from my server. Can I do this with WebMatrix? If so how?
View 1 RepliesI'm often experiencing that keyboard shortcuts stops working in WebMatrix. This is very annoying as CTRL-S, CTRL-C, CTRL-V, etc. stops working, all of which are heavily used when programming. It's obviously hard to explain how to reproduce this, but I waswondering if someone knows a quick-fix?

My hosting company states they support .net and razor. However after uploading my website made with webmatrix and razor *.cshtml pages. When i visit my website all i get is 404.17 error messages. As an testcase i decided to add an standard .aspx page. Visiting that page gives the same 404.17 error message :-(

According to my webhoster my web.config is wrong. However that one is generated by webmatrix. Besides my *.cshtml *.aspx a lot of files and directories are added to the bin folder. What can i check and what should my hosting provider check. When using the check compatibility the asp.net version is shown as unknown? My hosting provider claims my site is running asp.net 4.0 in integrated mode and that should be enough.
It's unfortunate that Microsoft WebMatrix (beta) doesn't recognize that files has been modified. I suggest you implement a feature similar to Visual Studio, allowing the user to decide what to do if the file has been modified outside WebMatrix. Especially when you have a button to launch the project in Visual Studio, it should have better support for "dual-development", cause at it is now, code can be overwritten by mistake easily.
View 3 RepliesI got the first beta of WebMatrix, downloaded Drupal, and got a site more or less going. I then tried to move it to two different hosts - first the IIS server running on my own domain controller, then to my hosting service. I dumped the DB with mysqldump, and imported it to the databases running on each server. Then I ftp'd the code and configuration files to both servers, and made appropriate configuration changes (primarily the mysql connect string).On both servers I have the same problem: The site comes up in its home page and looks great, but as soon as I log in as the site admin, I get a 404 (not found) error. Since it looks like virtually everything in Drupal is driven from the database, I really haven't the faintest idea where to start debugging this.

I know that I could use HttpServerUtility.UrlTokenDecode Method to do the job. But the problem is that I am using .NET 1.1 and this method is only supported in .NET 2.0+. Also I found that Convert.ToBase64String method is not an option because of the differences addressed here. So what other options do I have? Do I have to write my own converting method?
View 1 RepliesI have to send a file to my webservice, but the webservice assumes the file (byte Array) as a base64Binary.
Before the encoding, the byteArrayFile is saved on disk as a regular File. (I'm doing it just for testing)
So, in my Java client for webservice, I'm sending the information this way:
String file = new sun.misc.BASE64Encoder().encode(byteArrayFile);
port.sendFileToWebService(file);
The webservice have to decode the information and save the received file on disk.
[code]....
While saving password i am encrypting it using the following method:
public string base64Encode(string sData) { try { byte[] encData_byte = new byte[sData.Length]; encData_byte = System.Text.Encoding.UTF8.GetBytes(sData); string encodedData = Convert.ToBase64String(encData_byte); return encodedData; } catch (Exception ex) { throw new Exception("Error in base64Encode" + ex.Message); } }
I am creating a web site in .Net 3.5 , I am converting the string into Base64String to send it through querystring.The Response.Redirect works fine for smaller string. But if the original string size is 1670,the response.redirect results in error "Page can not be found".item is the string in below code snippet.
byte[] data = Encoding.Default.GetBytes(item);
return Convert.ToBase64String(data)
That subject may not do this questions justice.
I am trying to limit what I write on all my .cshtml pages. For example, on everypage I am @using myDLL and "connecting" to sql server.
I write that out like
@using System.myDLL;

myDLL dll = new myDLL();
dll.ConnectionString = "blablabla";
}
How can I remove the need to do that to every single page? I think I can create a web.config and do some funky stuff... can someone show examples?
