How to reduce Count when I hit back or delete dots?

giatuan2011 22-Jun-12 8:41am View

I mean you enter St and combobox appears.It will find the item named String.Press tab and richtext replace St with String

giatuan2011 22-Jun-12 8:38am View

The solution is useful.
It uses the system.dll.
I just added project> ClassLibrary in C# 2008 to make dll.But I will have trouble when I want to add function into .Dll file.I have to recompile dll.

Sorry,I use DropdownList in GridView.My RowDataBound:
protected void grdContact_RowDataBound(object sender, GridViewRowEventArgs e)
{
ContactTypeTableAdapter contactType = new ContactTypeTableAdapter();
DataTable contactTypes = GetData();
if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList cmbType = (DropDownList)e.Row.FindControl("cmbType");
if (cmbType != null)
{
cmbType.DataSource = contactTypes;
cmbType.DataTextField = "ProductName";
cmbType.DataValueField = "ProductId";
cmbType.DataBind();
cmbType.SelectedValue = grdContact.DataKeys[e.Row.RowIndex].Values[0].ToString();
}
//DataKeysName is ProductName.
}
I can get selectedValue when using:
grdContact.DataKeys[e.Row.RowIndex].Values[0].ToString().Insert(5," ");
if Productid is 'PS00000001',It can't get PS001

Your solution is very effective.I'm trying to trap errors number format when the User enter wrong

giatuan2011 15-Jun-12 0:14am View

So,the problem is Application variable?
I think I'll use Session when worker login then store in Application and lock it.All users can know workers status.But they can't logout worker.When the customer/worker logout,I'll check Session.If Session["worker"] exists,Application'll be removed.If not,he is the customer.He can't remove Application

giatuan2011 11-Jun-12 6:52am View

Thank you.I think I should get value from GridView and re-update Datatable

giatuan2011 10-Jun-12 8:02am View

I think I need prevent page refresh

giatuan2011 10-Jun-12 7:15am View

DataList have 5 columns.the page was bouncing up when I select item in the second row.It's like being refreshed.I think so

giatuan2011 7-Jun-12 9:04am View

So,It is Application[""]=value??

<appsettings>
<add key="Workerid">

It is what you say.You want to me use web.config?

giatuan2011 7-Jun-12 6:43am View

I just need to received an employee name.
You mean creating a normal variable in the page?
Ex:string WorkerName="<the employee's name after he login>";

Your solution is work.
But I have new problem.I need to create the id after assigning tbCart to Session ["Cart"].This only happens 1 time.I tried Random.It give me more id.How to make auto id?

giatuan2011 5-Jun-12 5:36am View

I just added:
tbCart.Rows[rIndex][2]=int.Parse(tbCart.Rows[rIndex][2].ToString())+slxuat;
But I have new problem.I need to create the "id" after assigning tbCart to Session ["Cart"].This only happens 1 time.I tried Random.It give me more id.How to make auto id?

giatuan2011 5-Jun-12 5:17am View

They are primakey key.
I think the OrderDetail has more products

giatuan2011 4-Jun-12 5:55am View

I tried:
void MakeTable()
{
cart.Columns.Add("idProduct",typeof(string));
cart.AcceptChanges();
Session["cart"] = cart;
}
protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "Add")
{
string product = e.CommandArgument.ToString();
cart = (DataTable)Session["cart"];
int count = cart.Rows.Count;
DataRow row = cart.NewRow();
row[0] = product;
cart.Rows.InsertAt(row, count);
cart.AcceptChanges();
Session["cart"] = cart;
}
}
And Bind as you.But GridView is empty

giatuan2011 18-May-12 3:30am View

I have the page use Master.I tried:
<script src="btnImage.js" type="text/javascript"></script>
I put images in folder named Image:
document.Button1.src ="~/Image/BTN.png"
It doesn't work.

giatuan2011 18-May-12 2:45am View

Thank you.I can use the theme?I think it will support all as tooltip,.....Where can I find a theme?

giatuan2011 18-May-12 0:16am View

I think I should use the Session.After logging in, the Session will save the username.I just need get the Session by refresh page.
I should put it to Pagel_load content page and mater
TextBox txtuser = (TextBox)Page.Master.FindControl("txtUser");
if (Session["username"] != null)
{
txtuser.Text = Session["userna"].ToString();
}else{
Session["username"] = "<get from="" database="">";
txtuser.Text = Session["username"].ToString();
}

giatuan2011 17-May-12 9:48am View

I mean username and password in Login.aspx, click login.And txtUser appear: Hi, <username>
I tried:
string sname;
protected void Button1_Click(object sender, EventArgs e)
{
TextBox txtuser = (TextBox)Page.Master.FindControl("txtUser");
ContentPlaceHolder con = (ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1");
TextBox tx = (TextBox)con.FindControl("txtusername");
txtuser = (TextBox)Page.Master.FindControl("txtUser");
sname = tx.Text;
txtuser.Text = sname;
}
It works.it is correct?

giatuan2011 17-May-12 9:32am View

I thought after load Dang.aspx,txtMaster will take the contents of txtContent.
But when I press the button btnGet, the content of txtMaster does not change.

giatuan2011 17-May-12 9:05am View

yes.I can set txtUser in Master load.But
ContentPlaceHolder con=(ContentPlaceHolder)Page.Master.FindControl("Content1");
TextBox txt = (TextBox)con.FindControl("txt"); txt.Text = txtuser.Text;
It does not display content of txtUser.
"contents pages loading event occuring before master pages loading event."
Oh,I understand why the txt does not show.I add button called btnGet in Dang.aspx and txt displayed content of txtUser.I can set content of txtUser after click btnGet.
Thank you.

giatuan2011 17-May-12 8:52am View

Oh,I clear txUser.Text in Master load and go to properties,change text of txtUser to Hi.
TextBox txtuser = (TextBox)con.FindControl("txtUser");
It works.I think problem is Master load:txtUser.Text="Hi".
So, How do I get and set txtUser after logging in without problem?

giatuan2011 17-May-12 8:33am View

you mean:in Dang.aspx,TextBox txtuser = (TextBox)con.FindControl("txtUser"); correct here?
txtUser is the control in Master.
txt is the control in ContentPlaceHolder.
When I remove txt,I can:
TextBox txtuser = (TextBox)Page.Master.FindControl("txtUser");
txtuser.Text="Hi,Guest";
After I add txt and change Master load:
protected void Page_Load(object sender, EventArgs e)
{
txtUser.Text = "Hi";
}
Dang.aspx:
TextBox txtuser = (TextBox)Page.Master.FindControl("txtUser");
txtuser.Text="change";
ContentPlaceHolder con=(ContentPlaceHolder)Page.Master.FindControl("Content1");
TextBox txt = (TextBox)con.FindControl("txt");
txt.Text = txtuser.Text;
txt is empty.txtUser is Hi.I can't change content of txtUser.

giatuan2011 17-May-12 8:02am View

TextBox t = (TextBox)con.FindControl("txt");
TextBox txtuser = (TextBox)Page.Master.FindControl("txtUser");
I tried:
t.Text = "Hello";
t.Text = txtuser.Text.ToString();
It appears "Hello" in textbox of the page Dang.aspx.
txtUser not change.
I not found Content1.It only has ContentPlaceHolder,Content,Page and Master.
How can I attach files?

giatuan2011 17-May-12 6:22am View

My ContentPlaceHolder Id is Content1 in Master.Asp.net 2005 and asp.net 2008 are different?What is Content2?
make Dang.aspx-> select master-> in design, I can not add anything to the ContentPlaceHolder.
I click CustomContent .. and Content 2 appears.
This is a problem?

giatuan2011 17-May-12 4:01am View

I tried your code and:
ContentPlaceHolder con = (ContentPlaceHolder)Page.Master.FindControl("Content1");
TextBox t = (TextBox)con.FindControl("txt");
TextBox txtuser = (TextBox)Page.Master.FindControl("txtUser");
t.Text is empty

giatuan2011 17-May-12 2:10am View

TextBox txtuser=(TextBox)Page.Master.FindControl("txtUsername");
txtuser.Text="John";
I can set it.When I add textbox into ContentPlaceHolder,I can not set value of txtUsername to textbox

giatuan2011 16-May-12 9:18am View

Sorry,Vasim889.I get good result from your code.Thank you so much
var q = dcon.sp_Login("John","123");
if (q.Count() ==1)
I have not changed, "John" and "123" to txtuser, txtpass.

giatuan2011 16-May-12 9:02am View

I found:
var c = (from user in context.tblUser where user.username = txtusername.Text and user.password = txtpassword.Text).Count();
if c==1->success.
How to I change it?

giatuan2011 16-May-12 8:32am View

select Count(*) is successful in sql server.
DataContextDataContext dcon=new DataContextDataContext();
string msg = "";
var q = dcon.sp_Login("John","1234");
if (q.Count()>0)
{
msg="success";

}
return msg;
not chage.Results as before

giatuan2011 16-May-12 8:12am View

It is successful when passw="1234".I do not think Count (*) returns the number of row.Proc does not return

giatuan2011 16-May-12 7:39am View

It doesn't work.Maybe I should use try catch

giatuan2011 16-May-12 6:55am View

You're right.Use the try {}catch{} for failure results and success
Thank you.

giatuan2011 14-Jan-12 4:23am View

I have an idea.
If I put an object as lines, rectangles into a PictureBox, I think it would be simpler.Then I just use Cotrols.Add to add PictureBox and move the PictureBox contains objects when user want to move line/Curve.
But I get a problem.That is the size of the PictureBox will change when clicking drawing.how to the transparent PictureBox background to the object behind don't lost?

giatuan2011 12-Jan-12 6:56am View

So,I should use the PictureBox and MDI?
If that's true,I just need events:Paint,MouseMove,MouseDown for controls.
Finally,I want to move the drawing object and export lines,circles,...into the vector file formats.
How to do it?

giatuan2011 29-Dec-11 3:24am View

great answer.
I just know say thanks very much.
I changed the class SockPack:
byte [] data = new byte [3] to byte [] data = new byte [1024];
and "UTF8" to Unicode.
I'm just a silly problem is how to scroll textbox to the last line

Thanks,your answer. I have access to Microsoft.DirectX and Microsoft.DirectX.Direct3D.C# has Matrix,not D3DXMATRIXA16,D3DXVECTOR3.I suspect my C# version too old.Google has some D3D code C++6.After converting C + +8. I got a lot of errors.I can not use other versions because my college uses 2005.
