From Windows Vista onwards, a non-administrative user must not write into C:\Program Files or C:\Windows folders; and even an admin needs to run the program in elevated mode when he wants to do so.
Write your files into a folder which is appropriate, e.g. %temp%.

Yes. I am writing my out dll files in a subdirectory of my project, which is placed on desktop. I hope that is fine.

ComboBox.SelectedItem returns you an object. Without guidance, ADO has no idea what to do with one of these. You could stick .ToString() on the end of the SelectItem maybe.
The code makes me feel uneasy, there's no validation anywhere and no domain object to represent a table row - I hope this is a quick and dirty application!

Rob Philpott.

Dear Member,
As per your code analysis , it is clear that you are using three comboboxes & one datetime picker control.
Since combobox control also returns object type instance, you have to mentioned here:
cmd.Parameters.AddWithValue("@itm", comboBox1.SelectedItem.Text); // if <a href="/Members/item">@item</a> is varchar.
cmd.Parameters.AddWithValue("@make", comboBox2.SelectedItem.Text); // if <a href="/Members/make">@make</a> is varchar
cmd.Parameters.AddWithValue("@dop", dateTimePicker1.SelectedDate); // if you are using RadDateTimePicker
cmd.Parameters.AddWithValue("@year", comboBox3.SelectedItem.Text); // if <a href="/Members/Year">@year</a> is varchar
Hope it help.
Thanks

Is it possible to execute few lines of code on installing a windows Store App? The lines of code that needs to be executed will be part of the store app itself.
So far, I am unable to find any information on this, but if any one has any info on this, please let me know. As of now I am trying to evaluate the feasibility.

The installation process is locked down to prevent tampering. Apps installed from the App Store are heavily federated so you aren't allowed to mess about with the installation. If you need to do something as a one off, do it when your application first starts up and mark that the task has been done.

Hi all,
I have created a MSI installer file which installs a desktop application. This setup contains many dlls which will be deployed to user's machine. Whenever I made changes to any one of the dll, I am again creating MSI installer and running the installation/setup. Or copying of dll also works. But my requirement is to publish these modified dlls and then this installed version of software takes the updated dll by itself. I do not want to do this activity again and again on user's machine to deploy the dll. Please suggest possible ways. All users are in LAN only.
Regards.

Create an updater application (as a Windows Service). It will be started automatically, looks into a folder somewhere on the network (make it configurable, e.g. a key-value-pair in its .exe.config file), compares the files there with local files, and replaces/adds them if necessary. Because Windows services use to run "elevated" with an administrative account, they can write into C:\Program Files and replace the files there.
Alternatively, your new setup packages can be installed automatically by Group Policies.

I am building an application based on MVVM approach shown in an article by josh smith. One of my user control has many controls (3 data grids and other controls) due to which its size has gone past the size of normal window. I tried adding a scrollviewer to the user control so that the user can scroll to see the hidden controls but the scrollviewer is not working. it is shown as disabled and during runtime the usercontrol only shows the controls visible in normal window size. The other controls are truncated. Can anyone please let me know how to add scrollviewer to workaspaces so that it can work effectively.
I am loading the workspaces suggested by Josh Smith in his article.

Whenever you have problem with sample from an article, the best approach is to ask the author...
Scroll down to the end of the article and there is a place to comment/ask...
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

how to search data from database between two dates using datetimepicker control in window form application asp.net C#
|
|
|
|
|
By executing a query, like SELECT [...] FROM [..] WHERE [..] BETWEEN @DatePicker1.Value AND @DatePicker1.Value).
That is assuming you know how to execute a query using C# and what SQL is. Documentation on the BETWEEN keyword can be found here[^].

Try:
using (SqlConnection con = new SqlConnection(strConnect))
{
con.Open();
using (SqlCommand cmd = new SqlCommand("SELECT * FROM myTable WHERE MyDateColumn BETWEEN @ST AND @END", con))
{
cmd.Parameters.AddWithValue("@ST", dtpStart.Value);
cmd.Parameters.AddWithValue("@EN", dtpEnd.Value);
using (SqlDataReader reader = cmd.ExecuteReader())
{
while (reader.Read())
{
int id = (int) reader["iD"];
string desc = (string) reader["description"];
Console.WriteLine("ID: {0}\n {1}", iD, desc);
}
}
}
}

yo.....
Curious.... Is C#f based Winforms better than MFC for GUI?
Which is faster to develop in?
|
|
|
|
|
Whichever you know better.
I mostly do console apps, but WinForms when I must.
You'll never get very far if all you do is follow instructions.

They're different, like a spoon, a knife and a fork. Which of those three is better?

The one that you're familiar with.

As the other have said, "It depends"
What it primarily depends on is if you know C# or C++.
If you don't know C++, then MFC development will be a real PITA in C#...
