I have a problem with this code. I am reading a value from a SQL Server and try to check it.
<br />
while(rdr.Read())<br />
{<br />
if(rdr.GetSqlValue(4)==1)<br />
{<br />
ArrayMandant.Add(rdr.GetString(0) + "#" + rdr.GetString(1) + "#" +<br />
rdr.GetString(2) + "#" + rdr.GetString(3) + "#" +<br />
rdr.GetValue(4).ToString() + "#" + rdr.GetString(5));<br />
}<br />
}<br />
I get a build error. Operator "==" cannot be used on objects and int. How I am able to check this value ?

You could either use a method of the SqlDataReader class that already returns an integer:
if (rdr.GetInt32(4) == 1)
or cast the return value of GetSqlValue .
if (((int) rdr.GetSqlValue(4)) == 1)

Hi,
You are getting that error because GetSqlValue is returning an object and you are trying to compare it with an int. Trying using GetSqlInt32 to get the column value instead of GetSqlValue.
Thanks

Hi
When i open a .tif file in picture box, i should be able to see or open all the pages. A .tif file can have any number of pages. I should be able to display all the pages in the picture box one by one. How can i do this?
I also need to zoom in and zoom out the image. Also scrolling of the image.
Can anyone help me? If possible please send me the code to open multiples pages of .tif files, zoom in and zoom out of image and scrolling of image.
|
|

|

you need to iterate through the tif file to get each individual image -
<br />
System.Drawing.Image i = System.Drawing.Image.FromStream(mem);<br />
int count = i.GetFrameCount(System.Drawing.Imaging.FrameDimension.Page);<br />
for (int x = 0 ; x < count ; x++)<br />
{<br />
i.SelectActiveFrame(System.Drawing.Imaging.FrameDimension.Page,x);<br />
Bitmap bmp = new Bitmap(i, i.Width / 2 * 140 / 100, i.Height * 140 / 100);<br />
}<br />
Then if you want to zoom the easiest way is probably just to change the width and height of your image.

Thanks a lot for this help.
can you tell me how can i display the corresponding frames in the picturebox?
right now the first page gets displayed. when i press the "next" button, i need the second page to be displayed in the picture box.
|
|
|
|
|
<br />
System.Drawing.Image i = null;<br />
int imageIndex = 0;<br />
<br />
public myForm()<br />
{<br />
System.Drawing.Image i = System.Drawing.Image.FromStream(mem);<br />
i.SelectActiveFrame(System.Drawing.Imaging.FrameDimension.Page,imageIndex);<br />
myPictureBox.Image = i;<br />
}<br />
<br />
private void button_Click(object sender, System.EventArgs e)<br />
{<br />
if(imageIndex >= i.GetFrameCount(System.Drawing.Imaging.FrameDimension.Page))<br />
{<br />
MessageBox.show("Reached end of images in tif");<br />
return;<br />
}<br />
imageIndex++;<br />
i.SelectActiveFrame(System.Drawing.Imaging.FrameDimension.Page,imageIndex);<br />
myPictureBox.Image = i;<br />
}<br />
You may have to update or refresh the pictureBox (but i dont think so)

Hi ronin,
You can access the database from the webservice in the same way you access from the other applications. The following lines of code connect to the database and return the results in the form of a dataset.
[WebMethod]
public DataSet GetData()
{
SqlConnection conn = new SqlConnection();
string connstring = "Persist Security Info=false; Integrated Security =false; database=DATABASENAME; server=DATABASESERVERNAME; User ID=USERID; Password=PASSWORD";
conn.ConnectionString = connstring;
DataSet ds = new DataSet("Employee Data Set");
SqlDataAdapter adptr = new SqlDataAdapter("select * from TABLE NAME", connstring);
adptr.Fill(ds);
return ds;
}
Hope this will help you.
Regards
SGS

i have created a server and client application.
i have ran the server but after a few days of running, it seems to utilize almost 100% of the processor, is this a problem of memory allocation (memory leaks)? if so, what should i do to address this problem? what are the tools which can be used to check if there exists any memory leaks?
|
|
|
|
|
100% utilitization of the processor probably means that there are a lot of threads running around. If you're looking to measure memory consumption, look for Memory Usage and related columns in Task Manager.

Senthil
