For those new to message boards please try to follow a few simple rules when posting your question.- Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
- Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
- Keep the subject line brief, but descriptive. eg "File Serialization problem"
- Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
- Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
- Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
- If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode "<" (and other HTML) characters when pasting" checkbox before pasting anything inside the PRE block, and make sure "Use HTML in this post" check box is checked.
- Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
- Please do not post links to your question into an unrelated forum such as the lounge. It will be deleted. Likewise, do not post the same question in more than one forum.
- Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
- If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
- No advertising or soliciting.
- We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
cheers,

I have the following setup:
Client: AngularJS Web App
Server: ASP.NET Web API
In the server I use the IdentityFramework3 to authenticate users on my AngularJS Client that has the (oidc-token-manager) configured.
Currently I'm setting the AbsoluteRefreshTokenLifetime to 48 hours for my Client MyAngularJsApp like so:new Client
{
Enabled = true,
ClientId = MyAngularJsApp.Id,
ClientUri = MyAngularJsApp.Uri,
ClientName = MyAngularJsApp.Name,
Flow = Flows.Implicit,
AllowAccessToAllScopes = true,
IdentityTokenLifetime = 300,
AccessTokenLifetime = 3600,
RefreshTokenExpiration = TokenExpiration.Absolute,
RefreshTokenUsage = TokenUsage.ReUse,
AbsoluteRefreshTokenLifetime = TimeSpan.FromDays(2).Seconds,
RequireConsent = false,
RedirectUris = new List<string>
{
MyAngularJsApp.Uri + "/assets/idSrv/callback.html",
MyAngularJsApp.Uri + "/assets/idSrv/silentrefreshframe.html"
},
PostLogoutRedirectUris = new List<string>
{
MyAngularJsApp.Uri + "/index.html"
}
}There is one specific user that will log into my client that I want to set his Refresh Token to last 100 days so that the user does not have to Authenticate in 100 days, the reason I need this specific user to have 100 days without needing to log in is because this user will be used to display a specific part of the app on a big monitor, it'll remain static for 100 daysAbsoluteRefreshTokenLifetime = TimeSpan.FromDays(100).Seconds How do I make it so that only this user has this refresh token lifetime?
[Edit]Reformatted the question so that it wasn't all inside one pre block.

Hi!! I've made an application with WinForm C#. How can I change it to application Sercvice. Thanks
|
|
|
|
|
Depends.
Services and Apps are very different beasties: services do not have a UI, WinForms apps do.
What is your app doing, and why do you want it as a service?

Please, stop trying to type the absolute bare minimum, or we will be here all day!
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with. And the better the information you give us, the better help we can give you.
So what does this app do with the info?
What should the service do with it?
What problems are you having in converting it?
What help do you need?

So, the "all day" option it is then ...
Just saying the same thing over again in bigger letters doesn't make it more informative - it makes it more annoying, but does not increase the overall level of information. And annoying the people you want help from probably isn't the best way to go in life.
Read what I said again:

1) Store it in a database?
2) Etch it on stone tablets and pass it down the mountain?
3) Strap it to the legs of pigeons and send it to your auntie?
4) Display it to the user in a neat and tidy way so he can understand what is going on in his computer?
5) Something else entirely?

wrote: How to convert windows application to windows service c#
I will answer the narrowest part of your question. Unless you're running on an old version of Windows, you cannot convert a UI based application into a windows service. A service is expected to have no user interface.
What you can do is extract the core logic that relates to the none UI part and host that as a DLL inside a service. If you need to communicate with a forms or WPF application you need to set up some form of communications protocol between the two. TCP is a popular choice.

I need help with breaking my algorithm into modules. The reason why is because the following code at the moment is essentially duplicated three times for each calculate button on my GUI Windows Forms Application. I was wondering if I break it down in to sub-routines this can be done? Can anyone help me with this?
public void park1()
{
string allotedTime = txtTimeLimit1.Text;
string startTime = txtEntryTime1.Text;
string endTime = txtExitTime1.Text;
if (String.IsNullOrEmpty(allotedTime) || String.IsNullOrEmpty(startTime) || String.IsNullOrEmpty(endTime))
{
MessageBox.Show("Enter all time values");
}
else
{
TimeSpan alloted = TimeSpan.Parse(allotedTime);
DateTime start = DateTime.Parse(startTime);
DateTime end = DateTime.Parse(endTime);
if (start > end)
end = end.AddDays(1);
TimeSpan duration = end.Subtract(start);
//If the start time is greater than end that means the diff is above 12 hours
//So subtracting the hours from a day to get the number of hours used if (TimeSpan.Compare(alloted, duration) == -1)
if (TimeSpan.Compare(alloted, duration) == -1)
{
overTime1++;
}
completeTime1++;
lblOverTime1.Text = "" + overTime1;
int percentage = (overTime1 * 100) / completeTime1;
lblOverTimePercentage1.Text = "" + percentage;
if (percentage > 50)
{
warnWarden();
}
}
}

Start by creating a seperate class (seperate from your GUI class) and pass the necessary data for the algortihm via or the constructor or via properties (or both).
The GUI should handle data validation input. Perhaps make the calculation buttons only available if the data is valid.
When the algorithm is finished it returns the result to the GUI who can display it.
Small pseudocode example.
function calculate(){
int n1, n2;
bool parse1 = int.TryParse(txt1.Text, out n1);
bool parse2 = int.TryParse(txt2.Text, out n2);
if(parse1 && parse2){
Calculator calc = new Calculator();
txt_sum.Text = calc.Add(n1, n2);
txt_substract.Text = calc.Substract(n1, n2);
}
}
function Add(int n1, int n2){
return n1 + n2;
}
function Substract(int n1, int n2){
return n1 - n2;
}
Of course this is a very quick and dirty pseudo code example, you'll need to work the rest out from there.
PS: If you want to do it properly move the calculations to some form of a business layer instead of just a seperate class.
Hope this helps.

When i have a Tabpage with Imagelist:
Generated by this code:
ListView lstView = new ListView();
lstView.LargeImageList = ListaImagenes[indice];
lstView.Dock = DockStyle.Fill;
for (int j = 0; j < this.ListaImagenes[indice].Images.Count; j++)
{
ListViewItem item = new ListViewItem();
item.ImageIndex = j;
lstView.Items.Add(item);
}
TabPage tab = new TabPage(Procedimiento);
tab.Controls.Add(lstView);
this.ImagesTabControl.TabPages.Add(tab);
What is the code to obtain a list of images selected?
Thanks

Hi All,
I am new to C#,I have built a scanning application using C# in visual studio which scans images in black and white but I would like to add a comobox fpr colormode which has options such as Grayscale and color
Basically I am wanting to scan images in color How do I Implement it?
Thanks in Advance
I have used the following code
namespace WindowsApplication
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
ListScanners();
// Set start output folder TMP
textBox1.Text = Path.GetTempPath();
// Set JPEG as default
comboBox1.SelectedIndex = 1;
}
private void ListScanners()
{
// Clear the ListBox.
listBox1.Items.Clear();
// Create a DeviceManager instance
var deviceManager = new DeviceManager();
// Loop through the list of devices and add the name to the listbox
for (int i = 1; i <= deviceManager.DeviceInfos.Count; i++)
{
// Add the device only if it's a scanner
if (deviceManager.DeviceInfos[i].Type != WiaDeviceType.ScannerDeviceType)
{
continue;
}
// Add the Scanner device to the listbox (the entire DeviceInfos object)
// Important: we store an object of type scanner (which ToString method returns the name of the scanner)
listBox1.Items.Add(
new Scanner(deviceManager.DeviceInfos[i])
);
}
}
private void button1_Click(object sender, EventArgs e)
{
Task.Factory.StartNew(StartScanning).ContinueWith(result => TriggerScan());
}
private void TriggerScan()
{
Console.WriteLine("Image succesfully scanned");
}
public void StartScanning()
{
Scanner device = null;
this.Invoke(new MethodInvoker(delegate()
{
device = listBox1.SelectedItem as Scanner;
}));
if (device == null)
{
MessageBox.Show("You need to select first an scanner device from the list",
"Warning",
MessageBoxButtons.OK, MessageBoxIcon.Warning);
return;
}
else if (String.IsNullOrEmpty(textBox2.Text))
{
MessageBox.Show("Provide a filename",
"Warning",
MessageBoxButtons.OK, MessageBoxIcon.Warning);
return;
}
ImageFile image = new ImageFile();
string imageExtension = "";
this.Invoke(new MethodInvoker(delegate()
{
switch (comboBox1.SelectedIndex)
{
case 0:
image = device.ScanPNG();
imageExtension = ".png";
break;
case 1:
image = device.ScanJPEG();
imageExtension = ".jpeg";
break;
case 2:
image = device.ScanTIFF();
imageExtension = ".tiff";
break;
}
}));
var path = Path.Combine(textBox1.Text, string.Format(@"{0}", Guid.NewGuid()).Replace("-", "").ToUpper() + imageExtension);
if (File.Exists(path))
{
File.Delete(path);
}
image.SaveFile(path);
}
}

Without knowing anything about what you're using to do the black and white scan, and it's capabilities, it's pretty much impossible to tell you what is going on.

Can anybody help me uploading images (also other files) like Profile Photo (as in Skype, WhatsApp-Web, TeamViewer) through a Windows application written in C#.NET.
Note that, user want to upload photographs from his Desktop application to his own web-hosting and the files should be saved in a special folder inside the hosting. Later, these photographs should be accessed through his web application

You seem to have the wrong idea as to what this site is all about, it is a developer site, for the betterment of developers not a supply code site. If you are building the application then we can help with specific coding problems.
As for uploading files there are many articles here that will show you how it is done. You question on free SMS, how do you expect to get the data onto the mobile network, magic!

I am trying to develop a solution for small business house. I am want to integrate something such that the user of the application software can send SMS to any number for absolutely free without using any API or SMS Gateway.
If any solution available to send SMS to WhatsApp or Telegram or to any Android App is also ok. Can anybody please help me on this.

SMS messages use the mobile telephone networks and all of them charge for it.

Well then, I guess you're not going to be sending any SMS messages to anyone.

|
|
|

All options have some cost associated with them.
Even if you tethered a cell phone, you would still need to pay for the phone line and SMS service.

I have a program that does color tracking from webcam, my question is it possible to do this tracking also in a previously recorded video.
the code uses a combo box to tell which webcam to use the image:
VideoCaptureDevices videosource = new VideoCaptureDevices (videoDevices [cameraCombobox.selectedIndex] .MonikerSting);
the webcam image is played in the VideoSourcePlayer and a "newframe" event has the color tracking code.
but I wanted to play a video saved on the computer in VideoSourcePlayer, so yes activate the event "newframe", so I tried to put a url
VideoCaptureDevices videosource = new VideoCaptureDevices (@ "url");
the program did not raise an exception, however, nothing is played in VideoSourcePlayer and therefore, nothing happens.
Is there any way to play a video from the computer in VideoSourcePlayer? What can I do?
OBS: I'm sorry for the English of google translator.
CODE:
videoSourcePlayer1.SignalToStop();
videoSourcePlayer1.WaitForStop();
videoSourcePlayer2.SignalToStop();
videoSourcePlayer2.WaitForStop();
videoSourcePlayer3.SignalToStop();
videoSourcePlayer3.WaitForStop();
VideoCaptureDevice videoSource = new VideoCaptureDevice(videoDevices(videoDevices[camerasCombo.SelectedIndex].MonikerString));
videoSource.DesiredFrameSize = new Size(400, 300);
videoSource.DesiredFrameRate = 12;
videoSourcePlayer1.VideoSource = videoSource;
videoSourcePlayer1.Start();
videoSourcePlayer2.VideoSource = videoSource;
videoSourcePlayer2.Start();
videoSourcePlayer3.VideoSource = videoSource;
videoSourcePlayer3.Start();
