I get following error: Target string size is too small to represent the XML instance
When I do this: repeater.DataBind();
How can I avoid this?
I am having an aspx page with controls as textbox ,tables ,checkbox etc .I need to convert the webpage to pdf file by a button click .I am using Itextsharp in it. when the button click event fires it shows the error as Font size too small: 0 near htmlparser.Parse(sr); Â
So how to rectify it .the code used for button click is :
protected void Button1_Click(object sender, EventArgs e) {
Response.ContentType =
"application/pdf";
Response.AddHeader(
"content-disposition", "attachment;filename=TestPage.pdf");
[Code] ....
Can somebody justify this statement with example: delegates represent methods that are callable without knowledge of the target object. i am not getting how we are hiding the function name at the UI.
View 4 RepliesIn login.aspx I have used login control to enter user name and password, the problem is: even my caps lock is off when I enter user name it prints in capital letters but size is small size (when I copy and paste in note pad or msword it paste in small letters not in capital letters), when I turn on my caps lock on and type - it prints in bigger size as if I am typing in capital letters.
ex: 1. temp is my user name if my caps lock is off it shows like this TEMP (but size in smaller than 2nd one)
2. if my caps lock is on is shows like this as if I am typing capital letters TEMP
what do you think the problem is how can I fix it
This is in my opinion an abstract problem and I hope I can explain it well. I happened to find the same kind of problem in a completely different project and now I have it again and I would like to avoid it if possible.
I'm creating some classes to simplify some tasks for some specific requirements we have in some projects at work.
I have a class that creates objects which maps the values from webcontrols to an object properties similar to this
[URL]
The problem I have it's sometimes I have to store a non container object in a place (in an object's attribute) and sometimes I have to a store a container object in the same place for storing the values of a webcontrol (a webcontrol can sometimes hold several values like a checkboxlist). I dont like this at all, because some time ago when working in a non commercial compiler, when parsing and generating the intermediate code I had sometimes to store a container in a place, and sometimes I had to store a non container in the same place, and having to ask in other parts of the code if what you are reading is this type of object, or this another type of object, it is something really annoying and it mess up the code. Is there any tips about what it would be better to do to avoid this kind of situations or nothing can be done to avoid it sometimes?
I read a CSV file into a DataTable.The DataTable in the first image shows each column and type.The types are exactly what they are supposed to be and the data loaded all the rows it was supposed to load.From the second screen shot you can see the database table. SqlBulkCopy is supposed to map column names to database columns by default.According to that logic each column matches up exactly to the database and the column types also match.However,when I run the command it errors on the first row with:
"The given value of type String from the data source cannot be converted to type decimal of the specified target column."
Here is the StackTrace:

I have a doubt concerning the Entity Framework in .NET.
I have a simple ASP .NET web page that has to insert some data in SQL Server with this function:
[code]....
The good news is that the code that Insert function encapsulates I can move it to the place which is called. So my question is: What if there is a place in which I would be forced to call the function? How then I could avoid the error. Passing the parameter as reference (I tried and did not work).
I am Developing a mid-size application and want to implement Application Architecture, I've read some Architecture Books and Approach and think about
AAFN (Application Arcitecture For .net) presented by Microsoft
SOA
SDLM
SDO
MVC
and vice versa ...
this is a web application that will extended with some other small application ( just think about something like a M.I.S with a (or two) core)
Whitch Projects I should have I think about
Common // to use in all projects
Framework // main framework
DAO // data access object ( entityframework or nHibernate )
UI // will available in 2 variant web and windows(wpf) interface )
BusinessEntities // all subApplication project logic will goes there
ApplicationNameProject // each application have their Own Logic (in BussinessEntities)
ApplicationUnit // each application Entity will place here
ApplicationNameProject // each application data Entity (in Application Unit)
Services // WCF Services goes here to contribute with all applications
this is the architecture witch I think about, I do not have any force to use this, I want to know whats the best fit for me, can Change all of it or add some other projects and remove these projects
If I have the following code:
TextBox txtUsername = new TextBox();
void setEnabled(string str, bool enable)
{
// use str to find the TextBox object
// str.Enabled = enable;
}
Is this kinda thing even possible? I want to be passing in 'Username' and then be prepending it with 'txt'.
What is the difference between
String (S capital)
and
string (s small)
Where to use String and where string?

View 1 RepliesI have applied a filter on a page using drop downs.
When i click on apply filter.. the page gets filtered. Now i click on the edit of filtered result.. which redirects me to another page.
I want to send the selected data from the drop downs from the filter page to the redirected page.. and again to the filter page.. to retain the filter. I am doing all this by sending the values in Query string.
Is there anyway.. i can avoid the visibility of the query string in the address bar and still get the values and required result.

I am REALLY stuck with this and need a solution in the next 24 hours .i I have uploaded my asp.net web application to the web and have the database and connection strings functioning and reading the data from the database. But when I try to write to the DB
I get the following error :

The wierd thing about this is the connection strings work from the local machine when I run from Visual Studio and I can write to the DB there, I just cannot write to the DB from the URL.
I am pretty new to asp.net but I am sure it has to be something to do with the web.config.

I am trying to create a simple login page in ASP.NET C# but am getting some error.
I googled about the error, and tried all the solutions but to no avail.What am I doing wrong? The error is:
"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"
I think it's something to do with my connection string which is as follows:
<add name="cn"
connectionString="server=HCL;DataBase=GS;Integrated Security=True" />
"HCL" is another machine connected to my PC through the LAN and this database, "GS", resides on it. Is the problem with the value I am giving in "Server" attribute of the above code? If not what else may I be doing wrong?
