textbox63 stays empty - C# Discussion Boards

Message Removed

I don't know what you mean when you say "... EF does not want the whole object but the ID only have the objects.".

EF will generate a primary key for a property that is or ends in "ID".

A relation is simply a statement such as:

public IList<Order> Orders { get; set; }

EF will create (entity model) relationships using the above "ID's" and "relation" statements.

I haven't used "xsd2Code" but when I paste "layered XML" in Visual Studio using Edit | Paste Special | Paste XML as classes, all the "layers" are converted to classes and a corresponding "relation" statement.

I've used the above to generate classes into which XML from 3rd-party web services was de-serialized; with no refactoring needed.

Hi there. I'm having a problem to create a program to get information from a website. First thing that I did was to put the login information with a HtmlElement, first I get the element with GetElementById and then I set the attribute, for click on login I get the element by button name and then I invokeMember("click"). It works fine but the problem is after this, the buttons are all in this way:

<img src="_imagens/sistemas/fig_PROJETOS_large.gif" onclick="sistema('PROJETOS','Acompanhamento de Projetos')" alt="Acompanhamento de Projetos" border="0">

So it does not have an ID, it is just calling the javascript function sistema that has some arguments. My question is, how I can run this button from a c# program since I can't found it by ID and then do a InvokeMember to click in this button? I tried to use webBrowser.Document.InvokeScript and others way but nothing worked to me.

Thanks for now. Thumbs Up | :thumbsup:

How can I manage printers on network, getting their status, ink level, if any printer have any problem then getting problem description,enable/disable printing on specific printer,etc.

All these I need to manage programmatically.

If my post helps you kindly save my time by voting my post.

I would think that would be determined by the api the printer publishes.

Never underestimate the power of human stupidity

Check out the System.Printing.PrintQueue and PrintSystemJobInfo classes.

The actual status information you get back for a given printer will depend on how well a given printer (driver) integrates with Windows.

(If a particular printer has "poor" Windows support, you will need to have access to the printer driver API; usually via a custom .NET dll supplied by the vendor, when available).

if your printer is connected directly to the network and support SNMP you can talk to your network printer and get what you want from him! i recommend you check SNMP feature of your printer ( if they have it !)

hii i was wundering. why my textbox keeps staying empty? i hope someone could tel me how ti fix it, my code stays below:

C#

private void Form1_Load(object sender, EventArgs e)

        cn.Open();
        dr = cmd.ExecuteReader();
        if (dr.HasRows)
        {
            DataTable dt = new DataTable();
            dt.Load(dr);
            dataGridView18.DataSource = dt;

        }
    }
    catch (Exception e)
    {
        cn.Close();
        MessageBox.Show(e.Message.ToString());
    }
    cn.Close();
}

C#

private void dataGridView18_SelectionChanged(object sender, EventArgs e)
{
    if (dataGridView18.SelectedRows.Count > 0)
    {
        DataGridViewRow dr = dataGridView18.SelectedRows[0];
        textBox63.Text = dr.Cells[0].Value.ToString(); // pad

    }
}

HOWEVER pictureBox1.Location=textbox63.text gives an empty result because textbox63.Text is emply but when i run my application textbox63.text isn't empy so why is this not working ???

dataGridView18
textBox63

Oh dear, oh dear, oh dear...
That implies that your one form as at least 18 data grids, and 63 text boxes. Tell me, would you like to sit down in front of that and use it every day? Why not? Because you can't find anything you are looking for? I certainly couldn't... Break it up, show a limited number of controls, and don't flood the user with info: it just confuses people.

Secondly, please stop using VS default names for controls. You may remember today what textBox47 contains, but will you in 3 months time when you have to maintain this? Use sensible names that describe the purpose of the control: it makes your code more self documenting, easier to read, and more reliable.

And third, what makes you think you have put a value in the textbox? The only code you show that refers to it will only do anything at all when the selection of the right datagridview changes. Did you use the debugger to check that the code was executed?

Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

the code is running because when i run the program with f5 textbox63 shows C:\Users\Master of Disaster\Pictures\wendy\beeldschoon.png. the point is i putted the location of an image into a database so that when i canged the picturebox and closed the application the settings are still saved when i re-open the application

Then you need to show us any code that actually does that, because the code you show certainly doesn't!

THNXX!! it works now !! the problem seems to be that the tabpage wasn't vissible.

No, that would be a very odd way to do things.

Just because you have found a solution on the internet, doesn't mean it's the right solution: and HTML / Javascript code for a website (especially as poor as that is) does not translate well into a WinForms or WPF application. That's like assuming that the first car door you find when you walk into a car breakers will do to replace the front door of your house!

Stop, sit down, look at your task, and try to work out what to do for yourself instead of hunting for a "quick fix" for your homework on the internet. It really will be a lot easier!

Are you writing a Windows Forms or a WPF application? What you are looking at writing is normally called a Login dialog, so you need to search for a Login dialog using the appropriate technology (e.g., google for wpf login dialog).

Hi friends,
i need to know if any possibilities to get controls like drag and drop and form creation and fields must be created regarding the controls created by user.
and storing retrieving values from database is that possible if any other ideas about this project link reference pls guide me

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
Edit your question and provide better information - don't try to be terse and save words: the better your question, the better the help we can give.

Hello to everyone,

Maybe anyone can help me...
The szenario looks like this...

There is a Mobile Device with Windows CE, a WCF Service hosted in IIS on Desktop PC and a Sybase Database hosted on a different Server.

I have to connect the WCF form the Mobile Device and get the Data from the Database.

If i test it from localhost (ASP.NET Development Server) everythink works fine, and i recive the data from the Database. If i connect remotely i can also connect the WCF Service but if i try to connect the Database the client app throws a systemerror and i don't know why

Maybe a problem in the web.config I am greatful for any hint

Hello again!

I have an issue regarding a search function for a datagridview to my MySQL DB.

The code is the following:

C#

DataView DV = new DataView(dbDataSet);
DV.RowFilter = string.Format("Name LIKE '%{0}'", textBox1.Text);
dataGridView1.DataSource = DV;

Now the search kind-of works, but it only displays the data if the name I search for is completely written out.
For example, if I want to search for "John", I need to write "John", or else it will not show anything.

What am I doing wrong?

modified 19-Feb-15 10:54am.

I don't know about MySQL, it has been a while since I used it. MSSQL would require the Like statement Like this:

Select * From SomeTable Where Name Like '%John%'

This would return anything where John is in the middle of the string. Your example would return data where John is at the end of the string.

HTH

Jack of all trades, master of none, though often times better than master of one.

Thank you very much! Appears I needed another % symbol at the end of the {0}.
Works flawlessly now. Big Grin | :-D

SVP aidez moi Cry | :((

En Anglais SVP.

I'm pulling in images from a camera at around 300 frames a second and i'm stitching them together. I'm not even close to being able to keep up with the camera currently. I was hoping I could get some of the experts here at CodeProject to review my code and point out anyways to make the process faster.

Thanks

C#
