Could you either post or send that code so that we can see? It's hard to pinpoint your problem when its like this without seeing it.

I have tried to dispose all datasets both in the windows version and the web version. No luck with the windows application though, still eats CPU.
When I test this I only use one page so the code is quite simple. We have one Main form that handles what page to show etc and one subform that displays the data.
Here is the code that is executed every 10 seconds from the main form:
private void timer2_Tick(object sender, System.EventArgs e)<br />
{<br />
YO.WindowState = FormWindowState.Maximized;<br />
TS.WindowState = FormWindowState.Maximized;<br />
MG.WindowState = FormWindowState.Maximized;<br />
DG.WindowState = FormWindowState.Maximized;<br />
<br />
string sTime = dataContainer.getTime().ToString();<br />
string sLimit = dataContainer.getLimit().ToString();<br />
string sVolume = dataContainer.getVolume().ToString();<br />
string sPages = dataContainer.getPages();<br />
string sProducts = dataContainer.getProducts();<br />
string sUnits = dataContainer.getUnits();<br />
<br />
ArrayList arrPages = YieldMonitorEngine.ExtractPages(dataContainer.getPages());<br />
ArrayList arrProducts = YieldMonitorEngine.ExtractProducts(dataContainer.getProducts());<br />
<br />
switch (int.Parse(sPageToView))<br />
{<br />
case AppConstants.MONITOR_YIELD_OVERVIEW: <br />
<br />
YO.InitializePage (int.Parse(sPageToView), int.Parse(sProductToView), int.Parse(sTime), <br />
double.Parse(sLimit), int.Parse(sVolume), sPages, sProducts, sUnits);<br />
MG.Hide();<br />
DG.Hide();<br />
TS.Hide();<br />
YO.Show();<br />
YO.Refresh();<br />
YO.Update();<br />
break;<br />
case AppConstants.MONITOR_YIELD_DETAILS_MONTHLY_GRAPH:<br />
MG.InitializePage (int.Parse(sPageToView), int.Parse(sProductToView), int.Parse(sTime), <br />
double.Parse(sLimit), int.Parse(sVolume), sPages, sProducts, sUnits);<br />
MG.Show();<br />
MG.Refresh();<br />
MG.Update();<br />
YO.Hide();<br />
DG.Hide();<br />
TS.Hide();<br />
break;<br />
case AppConstants.MONITOR_YIELD_DETAILS_DAILY_GRAPH:<br />
DG.InitializePage (int.Parse(sPageToView), int.Parse(sProductToView), int.Parse(sTime), <br />
double.Parse(sLimit), int.Parse(sVolume), sPages, sProducts, sUnits);<br />

TS.Refresh();<br />
TS.Update();<br />
YO.Hide();<br />
MG.Hide();<br />
DG.Hide();<br />
break;<br />
}<br />
<br />
<br />
string sLastViewedProduct = sProductToView;<br />
string sLastViewedPage = sPageToView;<br />
<br />
int iIndexOfLastViewedProduct = arrProducts.IndexOf(sLastViewedProduct.ToString());<br />
<br />
if (iIndexOfLastViewedProduct + 1 < arrProducts.Count) <br />
{<br />
sProductToView = arrProducts[iIndexOfLastViewedProduct + 1].ToString();<br />
sPageToView = sLastViewedPage;<br />
}<br />
else <br />
{<br />
sProductToView = arrProducts[0].ToString();<br />
<br />
int iIndexOfLastViewedPage = arrPages.IndexOf(sLastViewedPage.ToString());<br />
<br />
if (iIndexOfLastViewedPage + 1 < arrPages.Count) <br />
{<br />
sPageToView = arrPages[iIndexOfLastViewedPage + 1].ToString();<br />
}<br />

{<br />
sPageToView = arrPages[0].ToString();<br />
}<br />
}<br />
<br />
arrPages.Clear();<br />
arrProducts.Clear();<br />
}
When I test the application I only test with the case AppConstants.MONITOR_TOP_SYMPTOMS, so that's the code that is executed. The TS.InitializePage code looks like this:
public void InitializePage (int iPageToView, int iProductToView, int iTime, double dLimit, int iVolume,<br />

ArrayList arrUnitGroups = YieldMonitorEngine.ExtractUnitGroups(sUnits);<br />
<br />
ArrayList arrUnitsForProduct = YieldMonitorEngine.ExtractUnitsForProduct(iProductToView, arrProducts, arrUnitGroups);<br />
<br />
DataSet dsProduct = YieldMonitorEngine.GetProductInfo(iProductToView);<br />
<br />
if (dsProduct != null && dsProduct.Tables[0].Rows.Count > 0) <br />
{<br />
string sModelName = dsProduct.Tables[0].Rows[0][DBConstants.PRODUCT_MODEL].ToString();<br />
<br />

Can it be that I for some reason have some objects that I havn't disposed that I should? I thought .NET handled this automatically but seems like it wasn't that easy?

Dear CPians,
I have a problem within my ASP.NET application. The reason I am posting it on this Forum is that the problem is not Web related, its 100% C#.
I upload an image and I create an Image object from it. I do some Image manipulation like rescaling, rotating etc. and I create a Bitmap object from it.
Then I create another Bitmap object which is the Thumbnail of the first one.
I end up with two Bitmap objects. The original one and the thumnail. Now I need to save the two into the DataBase, (SQL Server 2000).
How can I convert the two Bitmap objects into byte arrays (byte[])? Any ideas?
Thanking you in advance!

How can i get system information, such as ip adresses,hdd properties, directories...etc of a local computer?
Can u give some examples?
Please help me
Tahnks everybody

For example:System.Windows.Forms.MessageBox.Show(Environment.CurrentDirectory);

You would have to get most, if not all, of this information using the System.Management namespace and WMI (Windows Manangement Instrumentation).
You can find examples of this on CP if you just search the Articles for 'WMI'. One example is right here[^].

I made an addin by using the Addin-Wizard of Visual .NET.
I should like to install this addin on the next configuration:
- A PC with Windows XP
- there can be several users, but they haven't administrator rights.
- The installation of the addin must work in the administrator mode, but users should use it in restricted mode (not admin mode in Windows XP).
So, I have problems, because the addin fail when it is launched in restricted mode.
Visual .Net print the addin failed during the loading.
Do you know a solution for this problem ?

i have problem with these topics:
why we r put signing key for the assebly.
ok i have created a class library called empobject.it's locating F:\KeyTest\EmpObject
then i have assign a key:
D:\WINDOWS\System32>sn -k F:\KeyTest\EmpObject\mykey.snk and the key is generated.then i have create a folder called SpecialLib in
D:\Program Files\Microsoft Visual Studio .NET\FrameworkSDK\SpecialLib cas
i want to copy all the non standard component here.
then i promt D:\Program Files\Microsoft Visual Studio .NET\FrameworkSDK\SpecialLib>gacutil -i empobject.dll.
but thr was a error called
Microsoft (R) .NET Global Assembly Cache Utility. Version 1.0.3705.0
Copyright (C) Microsoft Corporation 1998-2001. All rights reserved.
Failure adding assembly to the cache: Attempt to install an assembly without a strong name

hi,
Did you mention the strongkey name and location in AssemblyInfo.cs file of your .dll project.
Eg. please mention the vales for the below mentioned assembly attributes.
[assembly: AssemblyKeyFile("")]
[assembly: AssemblyKeyName("")]
After mentioning this. Try to compile your .dll file once again and then use Gacutil to install this .dll into GAC.

ya i don't have idea about the
[assembly: AssemblyKeyFile("")]
[assembly: AssemblyKeyName("")]
|
|
|
|
|
hi,
You will get this attibute on your AssemblyInfo.cs file which is located in your .dll project directory.
Before compiling your .dll you need to mention your strongkey file name and location. Just mention these information here and compile your assembly.
After your successful compilation you can go for Gacutil.
Eg.
[assembly: AssemblyDelaySign(false)]
[assembly: AssemblyKeyFile("C:\\Sreejit.snk")]
[assembly: AssemblyKeyName("Sreejit.snk")]
Here
AssemblyKeyFile - > the location where my Strongkey file is locating.
AssemblyKeyName - > is the name of strong file.
Try to compile your .dll after mentioning these two attribute. After this you can gacutil to install your .dll into GAC.

Nevar a problem. I won't encourage personal mails.
You can submit your doubt here in discussion. Sometimes this may help others.
I can't properly figurout what you mean by "non standard asemblies".
Tell me what is your real requirement.

but my empobject.dll is not display in the component list under the .net tab.
but other standard dll's(Crystalreportplugindil) list thr.so wht was the problem.

hi,
According me ,after completing your this requirement you need to study something about C# assemblies. Especially private and public assemblies.
The assemlies which are installed in GAC will show in the component list. But here you kept your assembly in your own location ( NOT IN GAC ). So it is upto you to locate the location of the .dll file.
Here what you can do is , Right click the reference folder and try to select add reference. Here you need to browse the location of your .dll file ( C:\yourDir\aaa.dll) and open.
So click on browse button and try to locate, open the .dll file.
After this you will came to know that your .dll is there in reference folder of your application.
Finally don't forget to study about Private and Shared Assemblies.

I validate all input data using a Validation class with functions like:
IsAlpha, IsAlphaNumeric, IsEmail, Lenght, IsNumber
Normally I make the validation in the Click Event of a form, and then I show the errors using an error control.
Is there a better way to validate input data? And for what are the events "Validated" and "Validating"?
Thanks.
|
|
|
|

hi,
If you are talking about windows application then you have to write custom functions like what you mentioned.
And you can provide ErrorProvider control for interactive error notification.
You can encapsulate your custom error checking here in Validated event of your textbox controls.
eg.
private void TextBox1_Validated(object sender, System.EventArgs e)
{
if(IsValid())
{
nameErrorProvider.SetError(this.TextBox1, "");
}
else
{
// Set the error if the name is not valid.
nameErrorProvider.SetError(this.TextBox1, "Name is required.");
}
}

Hello,
Is there any way to prevent a tool like Reflector (http://www.aisto.com/roeder/dotnet/) from reading and disassembling private members using reflection?
I am aware of a suggestion posted by Microsoft, stating that using [StrongNameIdentityPermission...] may help, but I can't find any example for a successful usage of it. Using
[assembly: ReflectionPermission(SecurityAction.RequestRefuse, TypeInformation=true)] (or any other flag)
also proved futile.
Can it be that an assembly created using C# and .NET has no secrets when challenged by a freeware tool? And say I have secrets, does it mean I have to stick with C++ (knowing that you need a capable disassembler and a more capable person to squeeze the data out of my modules)?
Best
