You need to add .NET redestributable package with your application. Then configure your installer to install framework first and your application. It looks like Visual Studio packaging won't provide option for doing this. I used a third party installer to do this. Try Installmaker.

Hi,
I have two fileds in a form both are combo box ie month and year and not data bound (form1) .

and from form2 back to form1
I have to show the same values of the combo ie month and year(which was selected by user ) when form 1 is loaded again
what is the correct way of passing data in two web pages in asp.net ie retaining the values of the drop down list in the form1
no use of sessions or global variables please What is the correct way of doing it
thanks in advance

It's not possible. Instead, you'd need to turn the two pages into controls, so they could both exist on one page, then viewstate will maintain the state of form1, even when it's not visible, and form2 is being shown.

Hi,
I am using a gridview to display user information, and one column I am trying to display the user's first name and last name together. They are 2 seperate properties in the UserInfo class.
<Columns>
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<a href='MemberDetails.aspx?MemberID=<%# DataBinder.Eval(Container.DataItem, "ID") %>'><%# GetMemberName(UserInfo)%></a>
</ItemTemplate>
<HeaderStyle CssClass="gridview_header" />
<ItemStyle CssClass="gridview_cell" />
</asp:TemplateField>
</Columns>
The GetMemberName method looks like this:
protected string GetMemberName(UserInfo info)
{
string strName = string.Empty;
// Check for a first and last name
if ((info.FirstName == string.Empty) && (info.LastName == string.Empty))
strName = "Unknown";
strName = info.FirstName + " " + info.LastName;
// Return
return strName;
}
I do not know how to call the GetMemberName method correctly from the gridview. Please can someone help me?
Regards
ma se

Where is the userinfo object coming from ? If it's the item stored in the datasource, pass Container.DataItem.

In a custom web control I took a look at some time ago, I saw that the writer programmer locked the thread before editing or reading from one of the member variables of the control (a generic Dictionary). Now, what I guess the locking does, because of the result of the script, is making that member variable a kind of application variable. My question is, how is it that the locking before touching the variable makes it a sort of application variable (available to all users viewing the page)?
Thanks in advance

Hi,
I am new to asp.net but have learnt a lot through the tutorials and random searching here and elsewhere. Have many years expereince with classic ASP but this task I am working on is sending me around the bend !
I want to have a nested repeater (this bit I understand fine) but am unsure how to make my data from two tables in the one database join together.
I have a table called boatcats which list a few different categoies of boat and I have a second table called 'boats' that list all of the boats and their details. The two tables share boatcats.ID and boats.catid
I doubt my code is heading in the right direction and I am unsure how to link the two queries. I am using VB not C# and should I be doing this sort of thing at code level (which I am used to in asp classic or with Visual Web Developer 2005)
Code so far is....
<script language="vb" runat="server">
Sub Page_Load(sender as Object, e as EventArgs)
If Not Page.IsPostBack then
BindData() 'Only bind the data on the first page load
End If
End Sub
Sub BindData()
dim dbconn,strq,dbcomm,dbread
dbconn=New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;data source=" & server.mappath("boats.mdb"))
dbconn.Open()
strq = "Select * from boatcats"
dbcomm=New OleDbCommand(strq,dbconn)
dbread=dbcomm.ExecuteReader()
boatcats.DataSource=dbread
boatcats.DataBind()
dbread.Close()
dbconn.Close()
End Sub
Sub BindData2()
dim dbconn2,strq2,dbcomm2,dbread2,boats2
dbconn2=New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;data source=" & server.mappath("boats.mdb"))
dbconn2.Open()
strq2 = "Select * from boats"
dbcomm2=New OleDbCommand(strq2,dbconn2)
dbread2=dbcomm2.ExecuteReader()
boats.DataSource=dbread2
boats.DataBind()
dbread2.Close()
dbconn2.Close()
end sub
</script>
I havn't added the asp:repeater section, this I have no problems with.
Any help appreciated.

Depends on what you want to do with the boatcats data i guess, but i will assume this is what you want in the repeater:
Boat Category
Boat Name
Boat Name
Boat Category
Boat Name
...
then you wouldn't need to have a nested repeater, you could do it in one repeater and just do a join in you database query:
"Select * from boats join boatcats on boatcats.id on boats.boatcats.id order by boatcats.name, boats.name"
(returning all fields from boats and boatcats) and order on the category name then the boat name.
OR
"Select boats.*, boatcats.title [boatCategoryTitle] from boats join boatcats on boatcats.id on boats.boatcats.id order by boatcats.name, boats.name"
(returning all fields from boats and boatcat title) and order on the category name then the boat name.
That way you can just put in two placeholders within the <ItemTemplate> and on the placeholder have visible="<%# ShowCategory(Container.DataItem) %>" (for the header placeholder) then visible="<%# !ShowCategory(Container.DataItem) %>" (for the boat section placeholder).
Then put a function ShowCategory(object dataItem) which works out whether this is the same category as the last, if not store the category name and show the header. Have another function inside that displays the name of the category. Then display whatever you want in the body section....
Does that make sense?? Is that what you are trying to do??

Thanks Daniel for the reply. I did think of the join in the query but brushed past it as I was keen to see what .net had to offer. Ultimately the page is to be searched on, and all boats regardless of matching the criteria are to be displayed. Those that match the criteria are to have an image in colour of the boat and the non search matching boats to be greyed out (A black and white pic of the same boat)
I did the whole exercise in under 2 hours in classic asp but am getting no where fast in .net !

You could probably use a nested repeater if you wanted to bring the data back in a dataset and provided information about the relationship between the two tables, but if you just need to display like above then this would be the better option.
Good luck.

Where is your respective textboxes ? Is it inside grid ? Do you want to implement this using javascript ?
|
|
|
|

the text boxes are out side the grid and i need to retrieve all the selected row information on clicking the link button (its data bound)item template of grid .
i was unable to fetch the text field of the link button under link button clicked event, if i can fetch the text of clicked link button i would be able to get all other credentials using new datasource.
i guess u got it pls let me know if any possible solns

Hi, I have a question, I very often get exceptions like: Object reference not set to an instance of an object.
Why does it occur?
for exmaple in this code:
SDSCheckUser.SelectCommand = "SELECT [newuser] FROM [Users] WHERE [username] = "+username;<br />
DataView view1 = (DataView)SDSCheckUser.Select(DataSourceSelectArguments.Empty);<br />
bool newuser = (bool)view1.Table.Rows[0].ItemArray[0];
Thanx

It means one of your casted objects returned null. You keep getting it because the code is poor - it should always check return values.

could be because if there is no user that matches the username there won't be any data at Table.Rows[0].ItemArray[0]....well that seems the most likely anyways.

Hi, I've read that usually if one wants to display binary data from a data store one has to read it using the ExecuteScalar() method of the SqlCommand class. Then caste the object the method returns by putting it in a byte array and display it like the following.
Response.ContentType = "application/pdf"<br />
<br />
Response.BinaryWrite(buffer);
How do I set the Mime Type of the file retrieved from the database dynamically? What I have in mind is this, suppose I have 3 fields in my database table with their data stored like the following:
ResumeID Int Resumes Blob ResumeTypes Varchar(50)
1 Something "application/doc"
2 Another Something "image/img"
I then get the value of the ResumeTypes field of my database and place it in the code like this
Response.ContentType = "Value of ResumeTypes"
How do I go about doing that? Thank you in advance for your help.

You'd do it exactly like this, store the mime type and pull it out of the DB.

Hi Christian, the problem is I'm unsure about how to retrieve the info from the database. I have already written code to connect to a database and retrieve data but its for a different purpose. The following is the modified code to try to make the program dynamically set the mime type.
For i = 0 To ListBox1.Items.Count - 1
If ListBox1.Items(i).Selected Then
DBCommand = New OdbcCommand("SELECT DocID, Document, DocTypes From ArchiveTB where Authors = '" & ListBox1.Items(i).Text & "'", DBConn)
End If
Next
If Not IsNothing(DBConn) Then
DBConn.Open()
DBCommand.Connection = DBConn
Dim DS As New DataSet
Dim AD As New OdbcDataAdapter(DBCommand)
AD.Fill(DS, "ArchiveTB")
AD.Dispose()
Me.ListBox2.DataSource = DS
Me.ListBox2.DataTextField = "DocType"
Me.ListBox2.DataValueField = "DocID"
ListBox2.DataBind()
Dim buffer As Byte() = New Byte(contentLength - 1) {}
reader.GetBytes(0, 0, buffer, 0, contentLength)
Response.ContentType = "" & ListBox2.SelectedItem.Text & ""
Response.BinaryWrite(buffer)
End If
Please take a look and see if I can do it this way. However, I don't want to force the user to choose the the mime type, how can I do this without using a list box? Thanks again for your help.

To reiterate advice I've given you many times before
1 - use real variable names, not listbox1
2 - don't grab text from a control to create SQL, it can be used for injection attacks
3 - don't iterate over a collection looking for the item that is selected, when the listbox has a selecteditem property
I despair that we are discussing the same function, week after week, but you don't actually take the advice given to you.
ASPnoob wrote: Response.ContentType = "" & CurrentModels.SelectedItem.Text & ""
Why are you grabbing the mime type from the CurrentModels control, and where does the buffer variable come from ? What does this have to do wtih ListBox2, anything ?
