Hi All,
I have one sample sql query and in where condition i need to put one value which is coming from dictonary object.
sample sql query: select * from XYZ where column1= {0}
so, i used string.Format(sql,searchvalue),
sql: query with where condition
searchvalue: Dictonaryobject(holds key and value)
but while debugging it is not replacing dictionary value and it is replacing text like
'System.Collections.Generic.Dictionary`2[System.String,System.String]'
i am a bit confused why it is not replacing with dictionary value.
can anybody help on this?

You need to use searchvalue["..."] where ... will be your key value. If you directly use searchvalue you will only get System.Collections.Generic.Dictionary`2.

To add to Abinhavs' answer: Don't do it that way anyway! When you do, you leave your database open to an SQL injection attack[^]
Do it this way
SqlCommand cmd = new SqlCommand("SELECT * FROM xyz WHERE column1=@SV");
cmd.Parameters.AddWithValue("@SV", searchvalue);Note that the convention is SQL keywords in uppercase, tablenames and fields lowercase.

Dear all,
I am new to C# programming and I need some guide on this problem. I am using MicroSoft Visual Studios 2005 C#.
I am given a task where i have to use the detections(in byte) received by the serial port, to
store them into points and appear on the interface form.
I need to:
1) use ReadByte Method to receive a single byte at a time from the serial port and to give a unique initial to the received byte detections by the HS0038B receiver. The detections must be categorised as X1 and Y1.
2)Create an ArrayList to store the bytes when the function ReadByte receive single byte.
Can anyone provide me with a small workable codes?
Thank you very much

I want to move a file with the following function but i get UnathorizedAccessException thrown. What could be the problem. When i try to move it to My Documents, it works just fine, only when i move it to the C Drive it throws the Exception mentioned. I'm really stuck.
private void MoveFile()
{
string fileName = "myFile.txt";
FileInfo fInfo = new FileInfo(fileName);
fInfo.MoveTo(@"C:\"+fileName);
MessageBox.Show("Done");
}

Have you got Admin rights on the box? Sounds pretty much to me like you don't have access to c:\
Can you manually move a file there in explorer?

When i move a file in C, i get a pop up saying Destination Folder Access Denied, then asks me to provide administrators permission. I click on Continue to get permission. Then i get permission and the file is moved. Is there a way my program can make such permission requests? What is the best way to go about this?

Well, security isn't really my thing, but your problem is clear enough.
First off, can you move the file somewhere other than root?
If not, you can fiddle around with the folder security on it and make sure the account you're using has full access to it.
And, if its that stupid UAC vista thing, I'd consider turning it off completely if you can. It's most annoying.
Regards,
Rob Philpott.

You can't copy anything to the C drive unless it's to the application data folder.

Its all because of UAC, google to run application as Administrator, vista will ask for the permission.
Actually, you are supposed to use the personal folder(My documents/App folder), in that case you will not face such problem.

I said that, but in a lot fewer words.

Hi, when uploading a image to a server, I get error saying directory not found. I am guessing its because its trying to find a path of users computer path in server and failing. in my localhost this works fine. how can i modify below code so that below line
System.Drawing.Image.FromFile(System.IO.Path.GetFullPath(flUpload.PostedFile.FileName))
maps to server. is there anyway i can get it working before actually uploading the original image to the server? thank you
using (System.Drawing.Image Img = System.Drawing.Image.FromFile(System.IO.Path.GetFullPath(flUpload.PostedFile.FileName)))
{
Size ThumbNailSize = NewImageSize(Img.Height, Img.Width, 100);
Size ImageSize = NewImageSize(Img.Height, Img.Width, 500);
using (System.Drawing.Image ImgThnail = new Bitmap(Img, ThumbNailSize.Width, ThumbNailSize.Height))
{
ImgThnail.Save(ImageThumbPath, Img.RawFormat);
ImgThnail.Dispose();
}
using (System.Drawing.Image Img1 = new Bitmap(Img, ImageSize.Width, ImageSize.Height))
{
Img1.Save(ImagePath, Img.RawFormat);
Img1.Dispose();
}
Img.Dispose();
}

Is code specifically for Windows 7 (through the win7 SDK) ignored if executed on a pre-windows 7 OS? or do you have to do OS version checks before calling any of it? or will it just not run at all?
|
|

You don't have to do anything unless you start using functions that are specific to Windows 7. The Windows SDK is cumulative, meaning that each revision builds on the last one to add support for features in the new O/S. It does NOT mean that the SDK is specific to that version of Windows.
If you're going to use functions that only work on Windows 7, then you've going to have to include code that checks to see if it is running on Windows 7 before it uses those functions.
