You cannot modify a variable name at runtime to point to a different value.
Perhaps a List or a Dictionary would be a better choice.
|
|
|
|
|
So you have variables called tb_Shift_1_Count_NG, tb_Shift_2_Count_NG etc? Surely you could call them tb_Shift[1].Count_NG ... and have a list of Shift objects instead of a whole bunch of variables.
|
|
|
|
|
I'd love to implement it that way, except tb_Shift_A_Coung_NG and tb_Shift_B_Count_NG are the names for the textbox. I don't think I can use an array for those, can I?

You can have an array (or list) of textboxes. That's not a problem.

I've implemented a tabbed browser that inherits from IWebBrowser2 and takes advantage of the BeforeNavigate2 and NewWindow3 events. When navigating to a new window, the event is trapped and the new window is sent to a new tab.
using System;
using System.Windows.Forms;
namespace BrowserTests
{
public partial class CustomBrowser : Form
{
public CustomBrowser()
{
InitializeComponent();
}
private void CustomBrowser_Load(object sender, EventArgs e)
{
this.CreateTabBrowser();
}
private void button1_Click(object sender, EventArgs e)
{
(this.tabControl1.SelectedTab.Tag as WebBrowser).Navigate(this.textBox1.Text);
}
private WebBrowser CreateTabBrowser()
{
TabPage tab = new TabPage();
this.tabControl1.TabPages.Add(tab);
this.tabControl1.SelectedTab = tab;
WebBrowser web = new WebBrowser()
{
Parent = tab,
Dock = DockStyle.Fill,
Tag = tab
};
tab.Tag = web;
SHDocVw.WebBrowser axWeb = (SHDocVw.WebBrowser)web.ActiveXInstance;
axWeb.BeforeNavigate2 += new SHDocVw.DWebBrowserEvents2_BeforeNavigate2EventHandler(axWeb_BeforeNavigate2);
axWeb.NewWindow3 += new SHDocVw.DWebBrowserEvents2_NewWindow3EventHandler(axWeb_NewWindow3);
return web;
}
void axWeb_BeforeNavigate2(object pDisp, ref object URL, ref object Flags, ref object TargetFrameName, ref object PostData, ref object Headers, ref bool Cancel)
{
}
void axWeb_NewWindow3(ref object ppDisp, ref bool Cancel, uint dwFlags, string bstrUrlContext, string bstrUrl)
{
WebBrowser web = this.CreateTabBrowser();
SHDocVw.WebBrowser axWeb = (SHDocVw.WebBrowser)web.ActiveXInstance;
ppDisp = axWeb.Application;
}
}
}
Some pages are trying to navigate to a new window marked as a frame: Site With Example Behavior
(second link is what I'm trying to replicate). Click the link, it opens a new window/tab... switch windows/tabs, click the same link, it should now navigate to the other window/tab that was just created. However, since each tab window is a new browser, the pages cannot find the frame to navigate to and it results in a new window every time, not just the first time.
I've tried the following modification but I don't have a reference to the new window's frame name...
void axWeb_NewWindow3(ref object ppDisp, ref bool Cancel, uint dwFlags, string bstrUrlContext, string bstrUrl)
{
foreach (TabPage tabPage in this.tabControl1.TabPages)
{
WebBrowser web = (WebBrowser)tabPage.Tag;
SHDocVw.WebBrowser axWeb = (SHDocVw.WebBrowser)web.ActiveXInstance;
if (web.Document.Window.Name == "targetFrameName")
{
ppDisp = axWeb.Application;
this.tabControl1.SelectedTab = tabPage;
return;
}
}
WebBrowser web = this.CreateTabBrowser();
SHDocVw.WebBrowser axWeb = (SHDocVw.WebBrowser)web.ActiveXInstance;
ppDisp = axWeb.Application;
}
If I hard code the name of the target frame on various sites that I know of, the navigation gets sent to the existing frame like it should and does not create a new window.
Anyone know how I can get the target frame name of a new window?
Thanks!

Hello there!
I have a third party web service that was written in PHP. I've added the web reference to visual studio and the methods take an object[] as the parameter.
Now according to their documentation if I were to create this client in php it would look something like this for the object[]:
$params = array(
‘username’ => $user,
‘password’ => $pass,
‘param1’ => $param1_value,
);
How do I create this in C#? I can't do Dictionary<string, string=""> because I can't convert that to an object[].
|

I tried your suggestions:
Custom Class:
class MCInfo
{
public string username { get; set; }
public string password { get; set; }
public string supportname { get; set; }
}
Linq:
List<MCInfo> info = new List<MCInfo>();
info.Add(
new MCInfo()
{
username = "administrator",
password = "testing",
supportname = "BLAH BLAH"
});
var results = (from n in info
select new
{
username = n.username,
password = n.password,
supportname = n.supportname
}).ToArray();
Invoke:
object[] blah = soap.domainEdit("blah.com", results);
Unfortunately it doesn't look like the other end is able to process it:

I haven't worked with XML or soap calls much.

That absolutely is a dictionary. I'm surprised a dictionary doesn't generate the correct service XML ... have you tried passing the dictionary as the only argument to the service method?
|
|
|
|
|
The problem with that is the only parameter it wants is an object array (object[]).
So how do I convert a dictionary into an object[]? They are completely different types of arrays.
These methods were generated when I added the service to visual studio. Maybe I should try calling the service manually?
|
|
|
|
|
You can try new object[]{ dict } which will create a one element array for parameters.
I don't really trust VS's automagical code generation but you can check the WSDL that the service exposes to see what the SOAP type of the parameter it expects is, and then try searching for that plus C# to see what .Net type will resolve to that.
|
|
|
|
|
I'll try to find that information. Browsing to the wsdl service this is what I see:
<message name="domainEditIn">
<part name="domain_name" type="xsd:string"/>
<part name="params" type="soap-enc:Array"/>
</message>
|
|
|
|
|
Hm, so that is just an array. Do you have a working PHP client? Try request-spying what it sends to the service and see what it's sending there. I had a very quick search and I didn't find a page explaining how PHP maps an associative array to a soap-enc:Array.
|
|
|
|
|
I don't have a working PHP client.
The API is here: http://www.mailcleaner.net/downloads/MailCleanerAPI.pdf[^]
They gave an example of this to call with PHP:
$client = new SoapClient(‘https:
$params = array(
‘spam_tag’ => ‘{This is a spam}’,
‘summary_frequency’ => ‘weekly,
…
);
$result = $client->domainEdit(‘domain_name’, $params);
if ($result[‘code’] == 200) {
echo ‘domain edited’ ;
}
So you can see that PHP is doing a multidimensional array.. but there isn't a way to create this array with C# and convert it to object[].
I haven't done it before but maybe calling the soap manually instead of using the web reference?

I did some cleanup in my code, and now I'm getting the above error message, but I'm having trouble seeing the reason. I searched the internet and found this article, but I don't see that I'm having that issue.
http://www.softwareandfinance.com/forums/index.php?topic=314.0[^]
In my Program.cs class, I have the following lines of code.
Control control = new Control();
Assembly _assembly = Assembly.LoadFrom(programDll);
Type _type = _assembly.GetType("CWriter.ProgramControl");
Object _objectInstance = Activator.CreateInstance(_type);
I tried adding a breakpoint in the ProgramControl constructor, but it doesn't get hit. The constructor doesn't have any arguments to it.
|
|
|
|
|
Wrap the Activator.CreateInstance in a try/catch block and then take a look at the full exception. Is there an InnerException that provides more details (there should be)?
|
|
|
|
|
That helped a lot. Thanks! It looks like it can't find a file that the class it's trying to invoke is trying to use. I had pulled some code into it's own SerialNumber class. That's the problem. Thank you!

Hello again! Another problem needs to be solved, when users click button1 it creates new row in table with text from textbox1. I need it before adding created row to table to check if record already exists in column "iestade_nosaukums". Here is button1 code for adding new row.
private void button1_Click(object sender, EventArgs e)
{
datori_database.iestadesRow newiestadesRow;
newiestadesRow = datori_database.iestades.NewiestadesRow();
newiestadesRow.iestade_nosaukums = textBox1.Text;
this.datori_database.iestades.Rows.Add(newiestadesRow);
this.iestadesTableAdapter.Update(this.datori_database.iestades);
this.Validate();
this.iestadesBindingSource.EndEdit();
this.tableAdapterManager.UpdateAll(this.datori_database);
}

In the time between "checking" and "doing your thing", changes could occur. It's no fun to hunt for race-conditions in code.
The best way is to skip that check altogether, and deal with an exception if it occurs.

yeah, you are right, it is easier this way, everything works now as it should. Thanks!

Rather than determining whether or not the record already exists, I would tend to use the following SQL:
INSERT INTO MyTable(SomeColumn)
SELECT @MyData
WHERE NOT EXISTS (SELECT SomeColumn FROM MyTable WHERE SomeColumn = @MyData) If you do a simple check, and then you do an insert and you are running this in a multi-user environment, you run the risk of adding a duplicate simply because you have two users doing the same checks at the same time.
As an alternative, put a unique constraint on the value you are trying to keep unique, and then just trap the resulting exception (this is not an ideal solution, but it is pretty much foolproof).

Thanks. I will try it later

Hello. So i have a filter that filters rows in datagridview:
private void button3_Click(object sender, EventArgs e)
{
iestadesBindingSource.Filter = string.Format("iestade_nosaukums like '%{0}%'", textBox1.Text.Trim().Replace("'", "''"));
}
When it doesn't find any records with criteria from textBox1.Text i need it to make visible label1.

Where's the question? Simply check if your bindingsource contains records, and if it doesn't, hide the label.

How to check if bindingsource contains records?
