I am creating a winform app in C# to store formatted text from a rich text box to MySQL database, which can be retrieved back to the rich text box. The database field is a VARCHAR and my code is something similar to below. But I'm getting "file not in correct format" error. Can anyone tell what could be the problem? Is the VARCHAR field okay to store it or should I change it to a BLOB?
string rtfText = this.richTextBox1.Rtf;
// save rtfText to database field as varchar
// ...
// reload rtfText from database as string
this.richTextBox1.Rtf = rtfText;
I have just opened my project and a RadAjaxLoadingPanel has got an error on it and deleted everything that was in it...
There is nothing in the design view or source view now...
I opened my back up from last night, and that is the same...
I opened my backup from Friday night and that is OK, BUT it will mean re-doing al of yesterday's work and a few hours from the weekend...
I tried copying the page from the server (I had uploaded the site last night and it's working fine), but when I try and open it I get 'This is a marker file generated by the precompilation tool, and should not be deleted!'...
Is there anyway to restore my page from the page sitting on the web server..?
I have a html textarea in my form, and when I postback the form, the value of textarea gets lost. I want the value of this textarea to be restored.I know that for restoring the value of textbox, I can directly use value=@Response["TextBoxName"], but this is not valid for text area, so I request you to suggest me a solution.
View 5 RepliesI have an ASP.NET page with a textbox and a button. In the textbox I enter let's say a name "Laurel" and click the button. The textbox is related as a control parameter to a data source and this data source pulls the content "Laurel" from the textbox to build a query, selects all orders of customer Laurel and sends them back to the browser where they are displayed in a list (gridview for instance). The list is long and has two pages (the list has a pager control). The list is on the same page where also the textbox is located. So I see now a page in my browser with the textbox (still containing the text "Laurel") and a list with a pager.
I could do now two actions:
Enter the name "Hardy" in the textbox and click on the button: The cycle above runs again and orders of customer Hardy are displayed. That's fine and what I want. Click on the pager control to display the second page of Laurel's orders. This works because I still have "Laurel" in the textbox. So on the postback triggered by the pager control the data source can extract again "Laurel" as query parameter from the textbox, run the query and deliver the second page of orders to my browser. That's fine too.
Actually there could be a third action:
I enter the name "Hardy" in the textbox, then change my mind and decide that I want to see the second page of Laurel's order. So I have "Hardy" in the textbox but don't click the submit button but instead I click on "next page" of the pager control to view the second page. On the server the data source extracts the content "Hardy" of the textbox, runs a query and then tries to deliver the second page of Hardy's instead of Laurel's orders. So that's not what I want. (Perhaps Hardy has only a few orders, not enough for two pages. The data source might tell me then "Nothing found" because there is nothing on the second page for Hardy.)
(What I mean can also be seen here on stackoverflow: Enter something in the search box, for instance "ASP.NET" and hit the enter key, you'll get a long result list with many pages. Then enter another term in the searchbox, for instance "PHP" but don't hit enter, instead click on page 2 in the pager control on bottom of the page. A postback occurs (which also transmits the new content "PHP" of the searchbox, I guess), the second page for keyword "ASP.NET" is displayed and the searchbox doesn't contain "PHP" anymore but instead again "ASP.NET".)
Question is now: How can I avoid a situation like this? My basic idea is: I need to restore the old value "Laurel" in the textbox to provide the correct parameter value to the data source query and my old value "Laurel" must be stored "somewhere" (on server? where on server? on client? if on client, hidden in the page or in a cookie or... ?). Are there some standard patterns to deal with this requirement? Or am I thinking in the wrong direction?
I'm trying to restore a sql server 2k8 database from a .bak file. I've tried using two methods and both are unsuccessful. I've tried using the SMO classes and the error that I get is simply "restore failed for <serverName>". I also tried to simply run a query with the proper syntax for restoring a database. This runs but I get an error message that says the timeout expired. I tried extending the timeout through the connection string to 20 mins but it still fails within a minute.
This is my code:

I had a web reference set in my VS2008 ASP.NET project, but due to some source control weirdness it is no longer listed in the project. I have the set of files in the Web References folder under my project. There's a .wsdl, .disco and several .datasource files. Is there any way to re-add this web reference through the existing files rather than using the "Add Web Reference" dialog?
View 1 RepliesI have two databases- database1 and database2. I have taken the full backup of database1 and want to restore it to the database2. When I do it in the Sql server Management Studio, I get this error:
The backup set holds a backup of a database other than the existing 'database2' database.
On runtime I am creating table structure using javascript and appending it to the div which is placed in an update panel. Problem here is, when I use asp.net button control, onClick of the button it posts the page to server and whatever javascript tables I have created it goes off. When I use html input button (input type="button") I don't face this problem and tables also stay there. But I have to use asp.net button to take necessary actions on the server side. Is there any way that I can restore the structure or use asp.net button control alongwith dynamic javascript.
View 1 RepliesIn my opening page of a web app I create (from a database get) two somewhat large datasets for 2 listboxes. I populate and databind them and all is good with the world
I then want to take those 2 listbox datasets and put them into a session variable for use on other pages of the web app. The reason is I do not want those additional hits in populating the two listboxes again (data does not change)
I am calling a class and passing back a DATASET for each listbox .. then
Session (DATASET_1) = MyClass.Dataset1
Session (DATASET_2) = MyOtherClass.DataSet2
DATASET_1 AND DATASET_2 are defines as constants with a type of DS
When I attempt to rebind the listboxes as
ListBox1.DataSource = Session( DATASET_1 ) *AS System.Data.DataSet ListBox.DataBind()
and the same deal for listbox 2 nothing happens........
I'm constructing a User Control that will have one Property called "ContractIdx". Here's how I've constructed this Property:
public int ContractIdx
{
get
{
return Convert.ToInt32(this.Attributes["ContractIdx"]);
}
set
{
this.Attributes["ContractIdx"] = value.ToString();
}
}
I'm initially loading the User Control by passing a parameter to it and setting ContractIdx accordingly. That all works fine.
Upon Postback though I'm loading the User Control without any parameters and then setting its ID property to what it was before the Postback. My understanding was that if I did this then ViewState would properly restore everything. Yet apparently this is not the case with the "ContractIdx" attribute.
Where am I mistaken in my understanding? How should I change things to get this mechanism to work?
I have a Gridview that is filtered by a DropDownList.
A sales rep can select all prospects or filter on the first letter of the company name.
They can also sort the complete list or filtered by sales rep name.
There are several reps in the list
It was requested that once the list is filtered by the first letter of the name
and sorted by the sales rep, that once they select a customer to edit in the DetailslView, and that
edit is completed by closing the detailsview, they return to the same sorted list. they return
to the same filtered list but the sort is back to the default which is the company name.
Here's what is in the code behind file.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (Session["selection"] != null)

In my opinion, these architectures have some differences, such as:
1. 3-layer is a linear architecture, but MVC is a triangle architecture.
2. Presentation Layer of 3-layer includes View and Controller of MVC? And Model of MVC includes Business Layer and Data Access Layer of 3-layer
I think 2 differences above are not obvious or are incorrect!

What's your opinion of the following job interview question?In the requirement it never mentions about to have classic ASP experience.
But the question is "What are the differences between ADO.NET DataSet and ADO Record Set?".
I think that I am confuse here. Now I am using WebParts as they being used on 2.0 framework (like they are using on TheBeerHouse kit)
But in most of the forums they talk about SharePoint. Does sharepoint means webparts as I know them, or this is a new version of the webparts?
We have a little debate and need to clear it up?
