I have a string variable that is a concatenation of text and a variable;
var selectQueryString = "SELECT * FROM WholesaleItems WHERE ProductClass like '" + @pc + "%'" ;
This returns with a space between the variable and the percent sign breaking the LIKE selector. I cannot find any way to trim the variable result.
I want to create a program that allows me to enter the name of a table, a field along with a value. The program should concatenate the values to form a valid SQL select statement. I can also modify the program to include multiple field names and values. Example: -Select “FieldName” from “TableName” where “FieldName”= “Value” I have created 3 textboxes called and 3 labels named Select, From and Where This is my code here, i would need an assistance on the right way to achieve this, maybe mine is wrong.
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim SelectItem As String
Dim From As String
Dim Where As String
SelectItem = txtSelectItem.Text
From = txtFrom.Text
Where = txtWhere.Text
lblDisplay = "Select" & " " & SelectItem & " " & "From" & " " & From & " " & Where
End Sub
End Class
suppose x=3,y=4
Response.Write(x.ToString + " " + y.ToString)
This gave correct as i thought: 3 4 But this gave unexpected result, so what's the rule behind string concatenation and conversion?
Response.Write(x.ToString + " " + y).
This gave :7. Why could'nt 'y' here got converted to string ? why arithimatic sum happend here?
how this string concatenation taking place? i am really confuse what is happening why that slash i there and how the double quotes are used
SessionStateItemCollection items = new SessionStateItemCollection();
items["LastName"] = "Wilson";
items["FirstName"] = "Dan";
foreach (string s in items.Keys)
Response.Write("items["" + s + ""] = " + items[s].ToString() + "<br />");
Response.Write("items["" + s + ""] = " + items[s].ToString() + "<br />");

I am developing a application in C#, ASP.NET and I have a lot os divs in my page, each div is a container for a chat message and each div have a unique id: like this
"<div id='" + myMsgs[j].id_chat_message + "' style='padding: 10px;'>"
so, each div have the same id in page and in database. now a want to find some div, with jquery, but it doesnt work
for (var j = 0; j < myMsgs.length; j++) {
findDiv = $('#<%= ' + myMsgs[j].id_chat_message + '.ClientID%>');
}
i know that my problem is the concatenation of the strings, but i dont know how to solve it.
using vb.net/asp.net 2005 and sql server 2005. I'm querying the database and returning text which I am then adding to a string. I'm creating a crystal report with the text however this is not a crystal report question, its about the string data. what I"m noticing is that when I show the string on the pdf that there are some strange characters at the end of the string. I am both trimming the string and taking out null characters however the strange text shows up like this:
strangeText>
SÙÇ
TÙçy|Ü
DÙÇ
$ÛÇ
</strangeText>
does anyone know what these characters are and how to get rid of them?
I'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
}
string First = "Hello World!"; string Second = "llo";
How can I check (true or false) if Second if within First ?
I am trying to retrieve xml from a small function in my .cshtml page. Its throwing me an error. This however, runs fine in a console/form environment. It takes 3 parameters and 1 exception.
[Code]....
Within my GetXML function it simply applies the parameters to a store procedure. The store procedure returns me my object. From there I can do all the fun stuff in .cshtml. When I manually enter the values from within SQL Management Studio, I do in fact get the right result. Again, when I create a Window Form application - I too get the right result! When it comes down to .cshtml or .aspx pages - I get the conversion failed. I have already tried casting the store procedure uniqueidentifier parameter and it still gave me that error.
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 using LinqToSql like this with a CheckBoxList in ASP.NET:
var teachers = from x in dc.teachers select x;
cbl.DataSource = teachers;
cbl.DataTextField = "name";
cbl.DataValueField = "teacherID";
cbl.DataBind();
I want to display both "firstname" and "name" in the DataTextField however. I found this solution but I'm using LINQ: [URL]
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've a string builder, and I need to convert it to a string, and then trim any commas if there are any there (I need to get rid of them because I'm building an sql query).
Here's what I'm doing:
myStringBuilder.ToString().TrimEnd(',');
Why isn't this working??? It's not trimming any commas at the end!
I'm using c# :)
