Re: Unable to change default color of Progress Bar control in winforms

8-Sep-13 22:28

You cannot set the color unless you remove the line Application.EnableVisualStyles(); from the main file.
This line enables the default windows color on your application.

Note that removing this line will have an impact on the entire form.

C# code making prolem when calling secure conection.

Why

From the documentation[^];

ForeColor and BackColor changes for the ProgressBar will not be honored when visual styles are enabled on Windows XP Home Edition, Windows XP Professional, Windows Server 2003 and above.

You'd could paint your own progressbar, or try one the articles here on CodeProject.

Make sure you are connecting to the url as https and not http.

C# vs Delphi. any ideas?

I am looking for few ideas & comments using the above technologies in,
- web based application,
- Large(which is good for future development)
- Faster(I guess Delphi)
- The development environment

Re: C# vs Delphi. any ideas?

8-Sep-13 22:22

There are even more facets to this.

For e.g.
It depends not only on your skill set but of the team you are planning to deploy.
I guess finding C# resources are better than Delhpi.

I would assume C# has a better development environment.

Current Row Select in DataGridView ...

That's like meat vs. cheese on a sandwich.

ASP.NET would be the most widely used; meaning it's easy to get devs that are familiar with it and that there's quite some documentation.

Swinkaran wrote:

What is "large" in your opinion? Does it generate a huge executable? Consist of multiple projects?

Swinkaran wrote:

In converting ints and adding them to a list, yes; Delphi would be faster. C# has a better overall performance, due to things like thread-pooling.

Swinkaran wrote:

I enjoy the VS2012 IDE; haven't seen the Delphi IDE since v6.

FWIW; it's allowed to mix both languages - I'd recommend using .NET, and to plug in your Delphi-code when you find that you "need more speed" or want to juggle with pointers.

Hi All !
The Event of btnNext_Click in DataGridView here is my Code :

int numOfRows = dgv.Rows.Count - 1;
int index = dgv.CurrentRow.Index;
if (index < numOfRows)
   dgv.CurrentCell = dgv[0, index + 1];
else
   dgv.CurrentCell = dgv[0, index];

the problem is I want to use :

dgv.CurrentRow=...

to Select Current Row .the property of CurrentCell active One Cell of Current Row.
Thanks

I'm not sure you'll get much help on this until you write in complete sentences and explain what the problem is more clearly.

The difficult we do right away...
...the impossible takes slightly longer.

That's indeed a problem; that property is readonly, meaning you cannot set it. You can set the current row by selecting it using the CurrentCel property, like shown below;

using System;
using System.Collections.Generic;
using System.Windows.Forms;

class Program
{
    static void Main(string[] args)
    {
        using (var f = new Form())                                  
        {                                                           
            var dgv = new DataGridView() { Dock = DockStyle.Fill }; 
            var lst = new List<Object[]>();                         // a list to hold values
            lst.Add(new object[] { 1, "One", DateTime.Now });       // add a record
            lst.Add(new object[] { 2, "Two", DateTime.Now });       // and another
            lst.Add(new object[] { 3, "Tee", DateTime.Now });       // ..
            dgv.DataSource = lst;                                   // assign the list as datasource
            f.Controls.Add(dgv);                                    // add dgv to form
            var btn = new Button() { Dock = DockStyle.Top };        // create button
            btn.Click += delegate                                   // when clicked

Probably by writing some code. But you need to give a much clearer explanation of your problem if you want some help.

Avoid space at the Start of the textbox

For which purpose? If you're looking for something that generates passwords, try a "normal" dictionary and specific character-replacements.

mory_260 wrote:

A key on the keyboard is usually responsible for more than one type of character. One can even type characters that aren't present on the keyboard, using an alt-numeric combination or an application like Windows' charmap.

With strings containing UTF16 characters, there's quite some more characters than keys Smile | :)

Well, you never specified where this code was, so I'll assume it's in the code for the form. That;s the wrong place to put it. Normally you would put code like this in a class that inherits from TextBox and create your own version of the TextBox to use. Then this code would go into the KeyPressed event handler of this new class.

Let the KeyPress event execute - just trim the textbox e.g.
(sender as TextBox).Trim()

Almost, it would have to be:

(sender as TextBox).Text = (sender as TextBox).Text.Trim();

But you would also have to check that .Text is not empty or null first.
